Citrus General Discussion / tanglefoot direct application experiment
« on: February 25, 2021, 01:43:38 PM »
I finally got around to doing this.  I just applied tanglefoot directly to the bark of a healthy 6ft-tall tree.  I applied it to a major limb (>1in diameter) and a small twig nearby.  I will see if there is any deterioration over time.   

If there is none... tanglefoot becomes much more useful to me.  It is a pain to put tape or some other backing for it to prevent it from touching the bark.  If it is harmless I can slap it all over.

Citrus General Discussion / best Pummelo?
« on: February 16, 2021, 10:34:18 PM »
Any opinions on the best pummelo available?  In the USA, I guess.  I really like Chandler, but I haven't tried much else.

Since the recent hosting migration I don't seem to be getting email notices when I receive a direct messages.  Is this just me or are others seeing same issue?

I just confirmed my Personal Message settings are set to notify via email as they always have

Citrus General Discussion / issue with Citrus forum?
« on: January 12, 2021, 06:09:07 PM »
The other day I was getting errors being redirected to when clicking on the Citrus section.  That problem has since gone away, but it seems we lost a few days of postings.

I didn't see anything unusual on the Tropical fruit sections.

After trying a new chinese restaurant I had some really good dishes that were full of these szechuan peppercorns.  They have a tingling effect that is described as another taste - in addition to salty, spicy, sour, umami, sweet, bitter, etc. 

Recently I've realized that some citrus has the same tingling effect.  Nagami kumquats are the most prominent, but even mandarins do this if they are still at least slightly sour. 

Wikipedia says szechuan pepper plant is in the rutacae family, same as citrus.  I wonder if the same chemical (Hydroxy alpha sanshool) is responsible?  Or if this is a property of anything sour.  I don't really remmeber this happening from sour candy or other non-citrus sour food.

Tropical Fruit Discussion / container black sapote seedling is flowing
« on: October 11, 2020, 11:10:58 AM »
I went out to my greenhouse to pick some oranges and noticed that my black sapote seedling has flower buds!  I bought this seedling just 16 months ago as a 4in starter plant and it is now 6ft tall.  Is it normal to flower in the fall?  What are the odds of having both male & female flowers?

Citrus General Discussion / first Sudachi fruit
« on: October 10, 2020, 02:29:08 PM »
The Sudachi tree that I got from Fourwinds this year is loaded with fruit, which are starting to turn a bit yellow now.  I just picked the first one and cut it open.  Tried the juice, flesh, rind, tried eating half of it whole.  I don't detect the unique flavor that is attributed to this (and yuzu) - it tastes like another lime to me.  Not very exciting.  I'll keep trying them over time as they ripen further to see if there's any change.

Citrus General Discussion / first grapefruit crop
« on: August 28, 2020, 08:55:01 PM »
My Flame grapefruit is producing its first crop this year, and it is huge.   There are so many grapefruits the bottom half of the tree is like a fruit igloo from all the branches being pulled down to the ground.  The outsides have a bit of color but still mostly green.  I cut one open last week and it looks like nearly full color inside.   Definitely edible but needs more time.  I know these are supposed to ripen in mid to late winter, but I think mine of off schedule.  They aren't ripe yet but they seem fairly close.  Hard to imagine they need another 4-5months.  I'm going to pick one every week or two until they seem right.

Citrus General Discussion / Trifoliate graft incompatibilities?
« on: August 24, 2020, 10:22:31 PM »
Are there any noteworthy incompatibilities with trifoliate orange/FD other than Eureka lemon?  I am trying to clone all of my trees onto these for dwarfing and clay soil reasons.  I donít know the rootstock for the vast majority of my trees and some are very vigorous when planted in ground-in greenhouse

Tropical Fruit Discussion / cattley guavas are great!
« on: August 15, 2020, 05:53:35 PM »
I just got to try cattley guavas for the first time, both red and yellow.  They grew and fruited quickly from seed.  I like them much better than any of the true guavas I've had so far (large crunchy white, pink, "regular" green/yellow).  I like the yellow ones a little more than the red, slightly sour while red is all sweet.

This yellow one isn't fully ripe, forgot to take a picture of the ripe ones I ate.

Citrus General Discussion / fruit split
« on: August 13, 2020, 01:18:24 PM »
I keep finding split mandarins on my in-ground greenhouse trees.  Only a small percentage of the crop, but enough I think it is a sign something needs correction.  Am I right that this is caused by drought stress followed by watering?  My trees are on drip irrigation that turns on for an hour every 3-4 days.  I just guessed, maybe it isn't quite enough.  The trees have never showed any sign of wilting so I figured it was good.

Citrus General Discussion / getting rid of excess trees
« on: August 04, 2020, 10:14:48 PM »
This week I sold a half dozen of my excess trees on craigslist.  I looked at shipping costs and realized it isn't realistic to ship trees once they reach a certain size.  I'm happy they went quickly to interested locals, but it is hard to see them go when they were producing fruit just fine.  I know at some point I will have to pick favorites and get rid of the *majority* of my trees, tough decisions ahead.  This time it was easy... meyer lemon, key lime, giant key lime, rangpur, and a calomondin are out. 

Tropical Fruit Discussion / asian grocery store fruit haul
« on: August 04, 2020, 09:25:39 PM »
I found fresh durian and purple mangosteen at a nearby asian grocery store today, along with sugar apple, jackfruit, muscadine grapes, and some asian cherry-plums?

Never had durian before, I thought I would have to travel to get a chance.

Tropical Fruit Discussion / Carombola / starfruit rootstock edible?
« on: July 12, 2020, 03:12:25 PM »
I have a Kari that I thought died, but the rootstock resumed growing from below the graft line.  Are these worth growing or should I toss it?  Scion is dead

Citrus General Discussion / splotchy yellow on leaves
« on: June 23, 2020, 10:43:53 PM »
My valentine pummelo is showing this leaf pattern I have never seen before.  In addition, the leaves are much yellower than my other trees, despite receiving mostly equal fertilizer.  This is planted in the ground in my greenhouse.  Any idea what this might be caused by?  Not all leaves show this pattern, maybe 2/3 do.  I can't tell if these are the older leaves or the newer leaves.  The unaffected leaves are have no spots and are darker green (normal looking)

Tropical Fruit Discussion / precocious pitangatuba
« on: June 19, 2020, 04:44:17 PM »
This might be expected to those familiar with them, but it was a pleasant surprise for me.  One of my pitangatuba seedlings already has a flower bud at 8" tall.

Tropical Fruit Discussion / armored scale infestation on mango
« on: June 14, 2020, 07:40:17 PM »
Is this "white scale" Aulacaspis tubercularis ?

Do systemic pesticides work for this?  I just applied imidacloprid to all my greenhouse trees (soil drench) the other day to help fight a widespread mealybug infestation.  This armored scale appeared last year... I sprayed with soap spray, but it has come back.  Only affects the mango tree, nothing else.

I am looking for a way to totally eradicate it, because in Pennsylvania I don't think this scale is endemic so I don't think it will come back.  In my experience smothering agents are only a temporary remedy

Citrus General Discussion / huge fukushu kumquats
« on: April 30, 2020, 11:13:23 AM »
As my trees grow they keep producing larger and larger fruit.  These are the biggest yet.

Unfortunately, though, the smaller ones taste better. 

Tropical Fruit Discussion / cherimoya flowering, cold requirements?
« on: April 29, 2020, 06:25:40 PM »
My greenhouse-kept grafted El Bumpo cherimoya looks to be flowering now.  At least, I think these are flowers, they are weird looking.  I believe these need to be hand-pollinated with a paintbrush?

My greenhouse never drops below 55F, I had read this is too warm to get fruit set on cherimoya.

Citrus General Discussion / all the containers come out tomorrow
« on: April 27, 2020, 07:52:39 PM »
I am excited that the weather is finally looking safe to pull all my containers out of the greenhouse and clean it up. 

Citrus General Discussion / hose burst, greenhouse flooded
« on: April 04, 2020, 10:30:33 AM »
I got a "too cold" sensor alert last night and went out to see there was over a foot of standing water!  I forgot to turn off the water to the hose in the greenhouse the other day, and it seems it had burst. 

I set up my extra garden hoses as siphons, taking 90% of the water out by the time I woke up this morning.  There doesn't seem to be any real damage so far.  I was shocked to see all the container plants had pretty much stayed put while floating because they are so tightly packed together.  A few seedling cups that were on the floor fell over.

My clay soil is very slow draining, so I am trying to dig small sumps and siphon out the remaining wet areas.  My understanding is that citrus should be able to tolerate flooding for a couple days without damage.  Hopefully no long term impact, I just have to clean up the white groundcover/tarp that is now buried in mulch that floated above it.

Tropical Fruit Discussion / flood tolerance
« on: April 04, 2020, 10:27:47 AM »
How tolerant are jackfruit, cherimoya, and green sapote to standing water?  My greenhouse flooded last night from a burst host I left on.   I siphoned 90% of the water out but there is still a couple inches around the jackfruit and cherimoya.

My quick research indicate that cherimoya and sapote are probably fine, but jackfruit is very sensitive to flood and could be damaged within 24-48hrs?   These are all in ground, in clay soil.

Tropical Fruit Discussion / black sapote seedling is taking off
« on: February 23, 2020, 06:33:11 PM »
this was only 6 inches tall when I got it this past summer, now it is nearly 6 feet tall!

My grocery store had them both.  $2.99 a pound, as expensive as it gets.  Both are huge apples.

Cosmic Crisp is really good, crisp and juicy.  Not sure if its as good as Pink Lady at its best, though.  Would definitely buy again if the price was lower or no other good options.

SugarBee was similar to Cosmic Crisp but simply not as good.  It is sweeter but doesn't taste better.  Would not buy again.

Citrus General Discussion / first Flame grapefruit
« on: February 08, 2020, 12:50:03 PM »
This is the very first fruit I've gotten from it.  It started in a container a couple years ago, took a huge hit from scale, I planted it in ground in my greenhouse last spring and it is now doing great.

Not much coloration on the outside, I was letting it hang but it came off as I was inspecting it.  Really juicy, nice color inside, not very sweet compared to grocery store ruby grapefruits.  Not sure if it needed more heat or if this type is simply less sweet.
