Had a brutal heatwave in SoCal yesterday. Reached at least 111F yesterday. Some folks reached 117F.
Was extremely lucky... didn't appear to have any immediate serious tree damage because I soaked trees the night before and sprayed intermittently on leaves throughout the day. Younger leaves shriveled up like prunes and small fruit fell off. Pushed mango grafts made in May and early June seem to have miraculously survived (although some were in a shaded greenhouse). Last week's mango grafts may be a different story. Hopefully the vented shade paper bags over the recent grafts helped. Will know more in a week or less. Crossing my fingers.

Brutal it is. I was expecting 110, it was 119 max and 114 all day. My trees were getting roasted. Moved what I could into the misted greenhouse which stayed in the 90s.

116 at my house 2 miles away at my moms 119. All the new growth fried loss hundreds of anona fruitlets that were setting quiet well. It’s 10am and it’s 99

I only got a little over 100 at my place but new growth from recent Mango grafts got fried. New leaves on Lychees got fried as well. I’m expecting to find sunburn on some mango, Dragonfruit and some Cherimoya fruit. Most my Cherimoya are under the canopy so most of them are protected. Good luck with the heat everyone.

Looks like someone ran through my yard with a torch. Terrible day. 113 degrees and less than 10% humidity, plus wind.
-
Yesterday reached 119 here as well by 4pm
I sprayed a couple of days before and watered early morning and during the day. Most new growth shriveled. Most trees did ok. I’m surprised that the trees hat I forgot to spray did just fine and showed minimal sunburn. I found some trees with significant trunk damage today though.

Lost a few young grafted mangos that is west facing in full sun. It hit 112 at my place in cerritos. My anemic lychees young leaf all got burnt. Not sure if it will make it. My yang mai leaves also got burnt but its a more establish tree.

First it was a fire breaking out. Ok, this one is 10 or more miles away. No big deal.
(https://c2.staticflickr.com/2/1786/43243068191_39656585f0_b.jpg)
Then things started to get a little more real when this one flared up just a mile or 2 away. I think this one was out on miramars land. Luckily it moved the opposite direction and got put out.

Was only supposed to get to 118 here. Thermo said 122 at 5pm. Even some of the guavas got crispy tips. New growth on the Sapodillas drooped until sun passed over to the west. Ice cream beans look a little distressed except ones underneath castor bean plants which I swear cool down the trees around it. Bananas got a little beat up too. Sugar apples are ok but lots of foliage on the cherimoyas is fried, even ones in almost full shade. Young white sapotes have looked miserable since yesterday around 11AM, they still look bad, even the ones in the shade. Surprisingly new growth on my lemon zest took it like a champ. Passion fruit, young star fruit seedlings and young newly transplanted figs weren't phased at all.

Well looking at the lemon zest, it did take more damage to the new growth than I thought. But it still seems like it takes the heat much better than my sweet tart, and definitely Coconut Cream. Maybe about the same as Keitt and "manilla" mango. The Coconut Cream may be delicious but it isn't particularly tough. Doesn't seem to deal with the cold or extreme heat well.

Sydney is about 34 latitude south and LA is about 34 latitude north although east coast and west coast climates are different. Sydney had a warm spell in January that adversely impacted on fruit trees. Air temps at the Sydney Cricket Ground Stadium during a cricket test were recorded at 135.7f and the nearest official meteorological station recorded over 117f.
By all reports the trees sprung back very well after being singed a few times in Summer so it doesn't have to be fatal for fruit trees.
-
Lol - I do love sunshine - mid 90's with full FL humidity is no problem. But over 100 starts to be too hot for me!
-
High humidity closer to the equator stops temps getting too high with 25 to 40 latitude and low humidity having highest max summer temps.
-
What a brutal heatwave we had in socal this last few days. I was off at work and didn't realize it could get this hot. Now that the temp has come down to within summer heat what is the best way to help those fruit trees and seedling pull thru without dying. I am concern for some of my cherimoya seedlings and grafted cherimoya seedling.
I brought all seedlings and grafted seedlings into as much shade as possible. I'm hoping those in the know have a plan.
Thanks,
Vincent.

Water and shade.

I agree. My lemon zest flushed through the heat with no negative effects. You can see the flush with no spray on it. Thee are even new flushes today. Still going.

Khaled, is that sunscreen?
I use a sunscreen from IV organics specifically made for trees. Also repels pest
-
There is spray can protection from sun scorching available.
-
The white stuff is surround wp. It’s a sun protectant l. Has worked well for me in past and safe to spray on leaves. I wanted some latex for the bark but timing didn’t work out for me.

Looks like he cares for it so well though. ;D My LZ wish I treated it like he does. I have lots of mulch but there's grass coming up all around it. I'm also done with protecting it from the sun anymore. It's getting too big to cover anymore and earlier this year I did cover it on our first 110+ day which did more harm than good, the shade cloth roughed up all the new delicate growth when the wind rustled it up against them. Mangoes are much tougher than I give them credit for. I need to stop babying them so much.
-
The Egyptian agriculture department advises to spray potassium Silicate and Amino Acids to reduce the heat damage. Unfortunately i did not find potassium Silicate in here but, I have a silicone based surfactant which should be good source of silica too.
-
I have lost 90% of all mango fruits. last year we had bad heat wave that took out over 75% of all cherimoyas. Hope its over for the year.

Sadly, similar reports amongst all our friends. The damage took 3 days to fully assess/realize.

It’s been in a pot for over a year and came through 1-2 minor frosts this year and is on turpentine rootstock. The fact that it’s got some new growth is encouraging to me now that it’s been in the ground for almost 2 months. No flowers in it though. Fruit punch has some fruit on it not affected by heat wave. Ambrosia growing well and has several flowers some have set fruit. I have a 20222 that has several mangoes but minimal vegetative growth or leaves after a large branch died off 3 months ago. I’m not sure if it’s worth keeping that tree around or replacing it. Mallika lost some frutlets but is flowering again. Kesar holding onto small fruit but has very few leaves on it. It’s not a vigorous grower for me over here 2 seasons in a row now.

I was out of town for the heat wave so I couldn't adjust my watering or protect any plants. I was told it reached almost 110 in Long Beach. Amazingly only a couple plants got sun burned. A couple of my blackberry plants wilted. My Grumichama has burned leaves all over it and dropped a lot of fruit. My two foot Sharwil Avocado also got burned badly. A couple of my mangos got burned but nothing too bad. And my Lemon Zest keeps dropping almost all its fruit. They split and then drop off the tree but I guess that is for another post.

We recently replaced our "dumb" sprinkler controller with a Rachio 3. It's pretty awesome being able to adjust the watering schedule or do manual runs from anywhere. It also uses local weather data to automatically adjust the schedule as well. I would highly recommend looking into one, if you travel often.

My LZ on Florida Turpentine rootstock did that for the first several years. After spraying it with a systemic Fungicide, it appears to be producing what appears to be normal Mangos without the cracking.
The temperatures have been very warm ever since the heat wave began and my plants are growing like crazy.

I have rachio and yes it is awesome. by the time I realized we hit 117 it was too late. now I have on demand heat wave schedule turned on,.

Just checked on some small guava trees I had planted in a spot that hit 116 F two days in a row -- not only was there no damage, but they were green and happy. (Meanwhile argan trees, which supposedly can handle desert heat, were scorched.)
-
The worst sun damage ive seen on guava is to the fruit on the exposed side and some minor damage to leaves. The seem to be be very resilient trees.
-
Guava is drought tolerant. Any drought tolerant tree fare better in heat waves.
-
We hit about 110 here in norcal. I lost some seedlings that were too close to my window :( Also had some leave damage on my 4 in 1 cherry, and avocados trees and mangos. poor avocados are just trying to recover from too much water, now they're getting fried!
-
lost all my mangos.
i had a wax apple tree that was bursting with flowers this year...all burnt to a crisp. i see a few survivors hidden below though.
persimmon dropped a bunch of fruits
some avocado shriveled up
some avocado trees in pots lost all the leaves.
longan leaves got fried and lost some fruits
and i had a champaca tree that just got fried too.
figs took it like a champ though.
i don't quite ever remembering a heatwave like this before? but then i really started to pay attention to this 5-6 years ago. man..just brutal.
-
The heatwave sucked! It killed back several of my new grafts and did this to my Dragonfruit.

Simon - ouch - so sorry for that loss.
Can they be salvaged at all - maybe into smoothies even?
-
I don’t waste fruit so I will just cut off the exposed pieces and eat the rest. It sucks that the Fruit cracked so early because they haven’t sugared up yet. This first fruit only had a Brix between 14-15% depending on which side I tested.
Simon
-
Simon, sorry to see that. Did the cracking happen like 10 days after the heatwave? I hope your loss is only limited to those in the pic
-
My Lemon Zest seemed to love the heat wave. And we are the 2nd hottest area in the nation next to Death Valley. The town I live in is literally called "Thermal". My LZ was only holding on to one fruit but looks like it will keep it til maturity. Picture is taken a top a step ladder about 10 days after heat wave. It burst out with growth right after it hit at least 122 degrees.

Out here in Riverside I have my trees covered with 30% shade cloth (younger trees) and I thought they held up well to that heat wave. But over a couple days they started showing the damage black sun burns on stems, roasted new growth, shriveled and dropped all fruit and now my little Mallika looks like it may be dead.
That said it looks like the best may have kicked my lancetilla that has sat around and done nothing for almost a year into growth.
Should I leave the shade cloth up the rest of the summer or just let it best down on them?
My manilla in the ground with no protection got roasted too.... But not much worse than the others

The HD/LA Verne "manilla" mangos seems really tough up against the heat. I have 2 at my renters home, and they accidentally shut off the water while trying to adjust the irrigation timer during the summer last year. Trees had no water for almost 2 weeks during our typical 110 deg days. Killed a 7 foot Morena Sapodilla, an avocado, and a guava. The 2 manilla mangoes survived, and they are full sun all day long, no shade. This year they are holding onto 40+ fruits ea even though they are probably 8 feet tall max
-
The lack of humidity is perhaps as important as the temperature for species from summer rainfall peak climates. Some politicians say future summers wont be any hotter than current ones so it shouldn't get worse for the trees in the future.

I also wasn’t here to water during the heatwave... there is a lot of damage, I’m hoping most will survive. But there are a few trees that I’m not sure will make it.

Waterfowler: with no damages at 122F, I wonder if it was high humidity at yours? My area was 115F but dry and all of my mangoes had burned leaves and fruits. Just a month ago I said the LZ that Simon gave me the cuttings finally held about 5 larger fruits -- about 2 to 3" long -- and I thought I would have LZ to eat this year, but the heat dropped them all; even Glenn couldn't hold any fruits. I think if I had covered the trees with bed sheets then perhaps some fruits could survive.

It’s sounding like we AZ growers need to pass along a few tricks to our so. Cal brothers. In no particular order....50% ( min) shade cloth on the west side for at least the first summer ( maybe two depending on growth rate). Larger root mass= better survival rate, so I mostly plant 7 gal trees, minimum. IF you have good drainage, mangos can handle a lot of water. If not, they rot out during heatwaves when you water every two days. I do DEEP watering three or four times in the spring to encourage deep rooting.
I grow a variety of silica accumulating plants to use as mulch, Vetiver grass topping that list. I also spray a few times in the spring to make sure the plant accumulated enough silica to withstand the heat. I also have worked to develop a microclimate that provides shade and humidity. Fast growing trees that can be chopped down in a few years are a great way of accomplishing this (morniga, tipu, ash,jacaranda, etc).
Plants have to be in good shape by the time June hits. I will gladly sacrifice a little growth in the spring by not pushing fruiting too young in order to have a healthier tree with better caliper growth.
I dig planting holes a year in advance and provide a lot of drainage via gravel, stones, pumice, etc. mixed with my planting mix. This allows compensation for settling, as well as establishment of fungal populations which can help augment roots. I will also will plant in Fall and baby plants thru winter if they are slower growing varieties. That gives a bit more root mass by the time June hits the next year. I can more easily compensate for our cool temps than I can for our brutal, dry summers....Fast growers like LZ and Peach Cobbler always do better in our heat than slower varieties. Dig BIG planting holes so roots can spread as fast as possible.
As long as the trees are in good shape during heat, I continue to fertilize lightly with fish emulsion (50% of recommended rate). This seems to allow for rapid recovery once our temps cool a bit and humidity rises again. If not in good shape, focus on moisture management and just getting the tree to survive. Danger zone is >105 and/or winds. I ignore crispy leaves and any crisped new growth and focus on keeping soil moist, not soggy, and do a quick hand misting in the AM and evenings to provide some relief to the younger plants.
Finally, I find a bit of amino acids and maybe a little superthrive seems to help avoid the worst damage. Absolutely avoid strong fertilization during heat. Trying to help by adding too much ‘stuff’ to your regimen is counter productive.
I hope this helps people. We in AZ are in uncharted territory when it comes to growing mango, so I hope my observations can help others avoid the 10 years of mistakes I have made.

We've had terrible humidity the last few days but during the heatwave it was very dry I believe. You can see the shade cloth right behind the tree which I've used in years past and up to this spring but I did not use it this time. It seems like the cloth just damages the new tender growth. Like DesertDreamer said above, I deep water my trees with a hose, not 3 or 4 times during spring, but every Sunday once temp start climbing above 110 degrees and stay there. Ranging from a couple of minutes to 20 minutes depending on the size of the tree. Also like DesertDreamer suggested I use accompanying trees/plants next to a lot of my subtropicals to protect them. Namely moringa and castor bean plants. You can see in the photo from my previous post a castor bean leaf off to the right. Their leaves are literally cold to the touch during the heat. Seems like young trees thrive around them.
The LZ and the "manilla" trees at my renter's house are the only mangoes of mine that see full sun most of the day. The other ones are still young and are semi protected underneath shade cloth or underneath larger trees/plants. My Coconut Cream and a CC seedling seems like they fared the worst under the heat wave but nothing major. It was brutal though. When I saw numerous guavas, which are normally tough as nails, with dangling limp leaves it concerned me greatly.

It’s sounding like we AZ growers need to pass along a few tricks to our so. Cal brothers. In no particular order....50% ( min) shade cloth on the west side for at least the first summer ( maybe two depending on growth rate). Larger root mass= better survival rate, so I mostly plant 7 gal trees, minimum. IF you have good drainage, mangos can handle a lot of water. If not, they rot out during heatwaves when you water every two days. I do DEEP watering three or four times in the spring to encourage deep rooting.
I grow a variety of silica accumulating plants to use as mulch, Vetiver grass topping that list. I also spray a few times in the spring to make sure the plant accumulated enough silica to withstand the heat. I also have worked to develop a microclimate that provides shade and humidity. Fast growing trees that can be chopped down in a few years are a great way of accomplishing this (morniga, tipu, ash,jacaranda, etc).
Plants have to be in good shape by the time June hits. I will gladly sacrifice a little growth in the spring by not pushing fruiting too young in order to have a healthier tree with better caliper growth.
I dig planting holes a year in advance and provide a lot of drainage via gravel, stones, pumice, etc. mixed with my planting mix. This allows compensation for settling, as well as establishment of fungal populations which can help augment roots. I will also will plant in Fall and baby plants thru winter if they are slower growing varieties. That gives a bit more root mass by the time June hits the next year. I can more easily compensate for our cool temps than I can for our brutal, dry summers....Fast growers like LZ and Peach Cobbler always do better in our heat than slower varieties. Dig BIG planting holes so roots can spread as fast as possible.
As long as the trees are in good shape during heat, I continue to fertilize lightly with fish emulsion (50% of recommended rate). This seems to allow for rapid recovery once our temps cool a bit and humidity rises again. If not in good shape, focus on moisture management and just getting the tree to survive. Danger zone is >105 and/or winds. I ignore crispy leaves and any crisped new growth and focus on keeping soil moist, not soggy, and do a quick hand misting in the AM and evenings to provide some relief to the younger plants.
Finally, I find a bit of amino acids and maybe a little superthrive seems to help avoid the worst damage. Absolutely avoid strong fertilization during heat. Trying to help by adding too much ‘stuff’ to your regimen is counter productive.
I hope this helps people. We in AZ are in uncharted territory when it comes to growing mango, so I hope my observations can help others avoid the 10 years of mistakes I have made.
Thanks for the great info Dessert Dreamer!

Thanks for the advice DesertDreamer,
We have some triple digit weather forecasted for our area of So.Cal starting this coming Monday the 23rd lasting thru Thursday the 26. Hottest days being Tues and Wed. @ 104.
Your advice came at the perfect time.

Out here in Riverside I have my trees covered with 30% shade cloth (younger trees) and I thought they held up well to that heat wave. But over a couple days they started showing the damage black sun burns on stems, roasted new growth, shriveled and dropped all fruit and now my little Mallika looks like it may be dead.
That said it looks like the best may have kicked my lancetilla that has sat around and done nothing for almost a year into growth.
Should I leave the shade cloth up the rest of the summer or just let it best down on them?
My manilla in the ground with no protection got roasted too.... But not much worse than the others
I wasnt here when the brutal heatwave occured & i lost the mangoes i have on sweetart and some minor leaf damage.
(https://s15.postimg.cc/req1zao9z/20180710_133806.jpg) (https://postimg.cc/image/req1zao9z/)
However, my 3 gals mango i received a month ago from florida took the brutal heatwave like a champ considering they get more sun than of the sweetart.

I noticed one thing in my yard post heat wave:
1. Mango plants that were holding fruit or blooms/fruit took a beating. I am talking about grafts and branches drying and dying 6-8 inches.
2. Mango plants that were young OR not holding any fruits/blooms, were unscratched or very little leaf tip burn. More importantly, plants that withheld without damage were in the hottest west side that also gets radiant heat reflected from west wall of my house.
I ask others to review and confirm this. I confirmed this with another fellow Gardner and it was exactly his case too.

So 2 weeks after the heatwave here's what some of my plants look like(well since it's been 103-114 every day since, pretty much every day is a heatwave here lol).
Banana chose to flower at wrong time. All the bottom fruitlets turned black shriveled up and died. Damage to top of plants too.

Best of all. My little Cotton Candy mango in container I bought from TT, which had done nothing in the 2 months since I received it in the mail, finally started to put on growth after the heat wave.

Hi, Behl,
I have about 5 small mango trees, none holding fruit and I dont see any damage due to heatwave.
Thanks,
FruitFool
-
Glad to hear fruitfool.
Let's see if other people can also confirm this
-
My Lemon Zest on Florida Turpentine rootstock is holding fruit and begging out and suffered no damage on its leaves or Fruit. A few recent grafts on this same tree has fried to a crisp but grafts that were put on several weeks before the heatwave actually pushed out vigorously.
I have a small double rootstock Sweet Tart tree that was holding three Fruit and all three Fruit cracked in half but there was no damage to the tree or leaves. All three Fruit are still hanging and I can see that there is no embryo in these three Fruit. I have noticed that the Fruit with atrophied seeds/embryos are more easily damaged.
The heatwave damaged my recently grafted scions the most.
Seedling trees that are not grafted are pushing vigorously.

I just heard on the radio that there is another heatwave expected next week.

Wednesday 7/25 will be the hottest, but temps won't go higher than 105F for those in Los Angeles area zones 10a and 10b.
So it's definitely not as bad as 7/06 for most.

I think it only got to 118 once last summer. That will be 5 days 118 or over before the end of July. Sigh.

I think this heat wave will be worse for us at least. It might be a degree or 2 under the peak of the heatwave 2 weeks ago, but the extreme heat will last much longer.

wow, and i was complaining about 97 yesterday, and 95 today.
ive been out spraying water on the leaves and mulch layer.
watch out for black containers !!!
they suck up that heat and fry the roots.
OK if its an edible root and your hungry i guess... :)
someone said humidity keeps the temps down ?
its 61% today, and often is over 80%. (90% in the morning)
i was out yesterday for 40 mins at 8:30am, before 9am i was soaked in sweat.
full clothing change including socks.

Hit 106 already and it's only 1 pm. New growth will get fried.

My sensors r currently reading 114f in the front with 25% humidity.

I have 6 sensors all around my yard and a Pro weather station. It gives me very accurate localized temps. At 106 it's 29% humidity. Which is unique as when we get to 100 our humidity dips to single digits.

97F 45% humidity and it's not even September the hottest month of the year. Wednesday's forecast 105F second heatwave this month.

A lot of the new growth on big LZ is looking bad and it's only day one of the 4 day heatwave. I might as well pull over the shade cloth or it will all get fried by Thursday. Guavas doing OK so far. Sapodillas all look rough, bananas too but I I can't do anything for them.
Plus it seems there's a fire every other day within sight for the last month or so.

I doubt it will be anything close to July 6. We are forecast at 105 on Wednesday yet it has been the hottest July of all times. The valley and riverside are hotter than north Orange County but we have the coastal influence which keeps our humidity in the 40’s.

Frank, there are pockets that get much hotter like Corona. it holds heat and cold much more than open areas. I hit 111 today, I am sure it could be repeat of July 6th in my area. I checked 3 other weather stations in my area and they were all within 1 degree +/- of my sensors.

I moved my potted mangos under my patio today and will keep them there till Thursday. Don't want to risk all that new growth. My Valencia pride after dropping it's fruit from last heat wave started pushing a lot of new growth. It's in the ground and covered by 30% shade cloth. It seems to have held up for today... But last time the damge started showing overa couple of days. I hope I can retaining the new growth... Because this canopy really needs to fill out

if water hits leaves, those leaves will get fried due to sun beaming onto the leaf via drop of water that acts like a lens. I wait until I get some shade around 5-6 PM.

Hi temps should make those grapefruits sweeter, I would think!
-
July 6th was brutal but so far this week my mangoes love it, and the big difference between damage and growth is the higher humidity of this week and dry on the 6th.
-
humidity plays a big role no doubt. I have been watering a lot to ensure there is local humidity as well.
-
This heat wave hasn’t been bad for me except for the fact that almost all my American Beauty Dragonfruit are cracked. Simon’s Purple is not cracking and Halley’s Comet is just setting fruit so no cracks on them.
My Mangos are starting to grow like crazy. The last heatwave was much more brutal.
Simin
-
for me, I lost a lot of anona flowers. when temps hit 100, I dont get pollen nor does the pollination work for me. females stay females and dry out OR there is no pollen to be had, extreme dry heat kills it. I dont bother pollinating when its over 100 degrees in heat wave.
do others have same issue?
-
Another 100F + day. I've loss many multigrafted branche, tress nearly all avocados and mangos..... chikos have been torched and loss fruits, lemons are dropping like flies and nearly all citrus fruitlets have dropped.
-
only thing thriving is freaking san augestine grass, guava, and palo verge trees. this heat wave was not as brutal although we hit 112 on Monday and 111 yesterday. But affects are not known until few days after.
-
This heat wave is much worse for me. The last one only lasted a day and most trees recovered fine, then put on new growth like crazy. We are on day 3, and the passion fruit which did fine last heat wave is all torn up, all the young annonas are in bad shape, bananas of course beat up. All new growth on my big Lemon Zest looks like crap. The tree that got hit the worst is my Alano sapodilla, which wasn't affected seriously last heat wave, this time I partially covered it and it still got toasted. The Hasyas and my Morena still look good but it probably doesn't make a difference, I will probably never get fruit from any of the sapodillas.

Freeze all your ugly dragon fruits for the season then use them to make dragon fruit wine at the end of the season. That's what I do

They still taste pretty good even though they didn’t fully sweeten up. I love the fiber they bring into my diet. The DF wine sounds pretty interesting.

You should make agua fresca from the pitaya
Very popular drink in Yucatán

That sounds refreshing, especially in this heatwave Frank. I’ve been juicing a lot of watermelon with a bit of cucumber and lemon/lime juice squeezed in and it’s been my go to drink I make for my daughters. I bet an addition of DF will add some extra nutrients and a tiny bit of flavor.

Do you soak the trees each time or just light watering?
-
One thing to consider in a heatwave is how you water. If you have your orchard set up on a drip system, it may be better to hand water to saturate the entire root zone including the mulch layer. By saturating the entire root zone, you will provide water to all the feeder roots and also increase the humidity around the tree. I’ve found that this type of watering prior to extreme heat prevents some sunburn that may have otherwise occurred. This is especially noticeable on Cherimoya and Lychees.
I normally water my plants with my drip system but prior to a heatwave, I will handwater deeply.

I run my rachio cycle that splits my watering time into 3 to 4 intervals resulting in deep soaking. I also sprinkled all leaves when sun was about to set to reintroduce instant moisture back into the leaves. not sure if its good or bad.
my watering is a hybrid of surface drip sprays and actual sprinklers.

That sounds refreshing, especially in this heatwave Frank. I’ve been juicing a lot of watermelon with a bit of cucumber and lemon/lime juice squeezed in and it’s been my go to drink I make for my daughters. I bet an addition of DF will add some extra nutrients and a tiny bit of flavor.
Simon
Get a greenpower juicer. I always find good used deals on ebay. I have one used (ebay) bought in 2005 and still going strong. Previous to that I had one last ten years that was bought 1995. In addition to my current greenpower I have one bought for back up in case the primary one dies. Bought that one cheap on ebay in the winter ($125 or so) when people are not into juicing....too cold in northern states.
Don't juice watermelon! Eat the red flesh and juice the rind. As you juice the rind add in a whole lime cut into quarters. Juice some ginger chunks too. So the outcome is:
juicing w a greenpower>>>
watermelon rind
lime (lemon is ok or other citrus)
ginger root
apple is cool too
I’ve been juicing a lot of watermelon with a bit of cucumber
A watermelon is a giant cucumber more or less and a lot less expensive. I must cut up some watermelon rind sometime and add to a salad and see how it tastes. Peeling off the watermelon skin of course. Last week at Aldi's seedless watermelons going for $2.50/////Yikes I got two in my refrigerator. (no I am not a vegan)

Thanks for your the tip Zands, I’ve got an old Jack Lalanne juicer I use for speed juicing and I have an Omega NC900 slow juicer for juicing greens like wheatgrass, spinach and almost anything else that can benefit from the reduced heat and oxidation of a slow auger type juicer.

Please notice in yr YT video this is the same John who has gone around America and showing off peoples gardens and groves. I have an omega juicer as a back up to my backup greenpower. Omega is slow RPM like greenpower. It is less efficient (maybe 5-7%) to greenpower with its twin augers as far as getting the juice out
I am fairly certain (iirc) that for wheat grass the single auger Omega does it better than greenpower. Less foaming
Here is John at Bender's Grove in Davie / SW Ranches Florida
https://www.youtube.com/watch?v=pel0PJIBMfI (https://www.youtube.com/watch?v=pel0PJIBMfI)
John has a business selling every kind of juicer. http://discountjuicers.com/ (http://discountjuicers.com/) He sells the good, the bad and the ugly. He also sells the superior ones too.

One thing to consider in a heatwave is how you water. If you have your orchard set up on a drip system, it may be better to hand water to saturate the entire root zone including the mulch layer. By saturating the entire root zone, you will provide water to all the feeder roots and also increase the humidity around the tree. I’ve found that this type of watering prior to extreme heat prevents some sunburn that may have otherwise occurred. This is especially noticeable on Cherimoya and Lychees.
I normally water my plants with my drip system but prior to a heatwave, I will handwater deeply.
Simon
I don't have lychees and all my anonnas have stayed the same height (1-4') for the last 3 years because of our extreme temps, but I have noticed the same thing. I try and hose water deeply at least every other day during heatwaves and it definitely makes a difference regarding sunburn. Without lots of water, the leaves get droopy, and the sun cooks them off in short order when they are in that state. In years past I just increased the amount of irrigation time when it was hot, but with much less satisfactory results vs hose watering.
Thankfully temps return back to normal after this weekend.

The first heat wave was brutal. This one didn’t do as much damage but still did a number on my grafts that were still holding on. Like Frank, I also lost my multi branch graft as well as one mango tree with Lemon Meringue graft has bitten the dust.
On another note, my lemon zest is pushing new growth as well as my Pineapple pleasure and my new Orange Sherbet trees are liking the heat. I have kept the 2 OS trees indoors by the slider glass door for heat and ventilation. They are looking real nice.
One question I do have.... at my house, my yard gets the early sun on the west side of my property with shade on the east side where I have been keeping my potted trees. Towards the evening, the sun is beaming the east side of my yard where my trees are while the west side is now getting shade. My question is...should I move my plants to get the early sun on the west side instead of keeping them in the early shade? I feel that the later heat/sun that is hitting the trees is more intense .
Any thoughts or advice is appreciated. Am I wrong in thinking that way? Does the afternoon heat do better for the trees?

Also lost my Lychee 😩😩

108 temps right now here.
I havent watered my trees for 3 days now unmulched. 8)

You asked for advice so here it goes from 3000 miles away.
Fruit trees are 5-10-15-20 years projects.
So do the utmost to shield your fruit trees from what is passing and temporary and just this year.
SHEILD them via extra hose watering and shading them and you will be rewarded in future years as they thrive.

Just looked at the forecast for the next 10 days and it’s not going to be cooling off anytime soon.
I will be shielding come tomorrow.
Although the forecast says it won’t be in the triple digits for the next 10 days, it will still be quite warm.
We will be cooling down to 95 on Saturday. All the other days on the forecast show 98 and 99 degrees.

Lionking, I would put them into ground once they stay in your pot for 6 weeks or so, carefully put one in ground and then next after first makes it.
Mid 90's in corona is perfect weather. What is your forecast?

93f 50% humidity very muggy here.

93f 50% humidity very muggy here.
But this is perfect weather for mango vegetative growth.
Not only an emergence of young leaves....but young grasshoppers too!

Lionking,
the sun rise on East and fall on West. The side that get morning sun is the East side.

Lionking means that he has a taller block wall on the west and east sides of his property. So his post is a correct statement. I have a similar situation as to what he described.

Hey Behl,
Thanks for the info.
The forecast for my areas next 10 days is ... 98 tomorrow, 95 Saturday, then 98 and 99 the next 8 days.

Yes Warren, you are absolutely correct.
My thought is that as the sun rises, it would shine on my trees in the early morning heating them up gradually as the day goes by. Where as in the mid to late afternoon when sun is at full heat and shining on the east side of my property, it is scorching the trees till it goes down.
The taller block wall on the west side will be providing the shade and some relief to the trees near it towards the end of the day.
So I am curious if that is a good idea or should I leave them where they are at on the east side?

Lionking....it's okay to leave them on the east side block wall. I have 7 trees on the east side wall and 3 trees on the west side wall. They all seem to be doing equally well. Of course the trees along the north side wall get the most sun...but also got scorched the most too.

Thanks Warren, that will save me from some back pain.
After having some losses, I was beginning to overthink things I guess...lol
Yes I’m willing to do anything to keep from losing my mango trees and any future grafts.

I feel lucky while reading you all's temps! My yard is about 89-90 but high humidity- yesterday it was approaching 70% at 90 degrees. I'm good with it, I just stand out there and sweat as the sun goes down, watering my trees. I did lose some trees to the first heatwave however, 2 Jamaican cherry's in pots (under a large tree) and my beloved pedali tree...poor guy made it through the winter only to bite it with one insanely hot day. Good luck to everyone. Chris
-
I moved my cherry tree (4 in 1) inside for a bit and in the last couple days it's seem tremendous recovery. New growth all over the branches. I was worried the heat had fried the ranier graft but it's making a comeback! I think the smoke from the carr fire up here is helping too... unfortunate as it is. The shade's helping alot of my plants that have been struggling with the 110 degree weather and sun.

Its been hitting 100-102 consistently in last one week or so in my area (corona, ca), got no damage from recent heat wave when I hit 112, 110, 114, 105, 104, etc. triple digits continue, high humidity has helped, mangoes are flushing like crazy.

We have similar temps highest i had was 116 the past week. Mangos too are growing crazy. I hope we get at least 3 -5 flushes more by the end of the year.

what's funny is small sprout out of seedling pushed within 2 weeks of first flush. LOL

This heat has become tiresome. 116 today. Doesn't get below 110 until Monday 8/13. I don't remember it ever being this hot for so long. Can't wait for the typical 104-108 deg days.
Most of the trees are holding up surprisingly well though

And Summer is over in the Nth Hemisphere. The southern hemisphere may experience very warm conditions soon also.Predictions for northern Australia are for very high Spring and Summer temps. Places like Katherine and in nth WA already reached over 100f before winter had finished.
