Tropical Fruit Discussion / Re: Mango Pests, Diseases, and Nutritional Problems
« on: August 16, 2022, 03:28:52 PM »
Thank you Mangoba and Jakefruit for your replies.
@ Mangoba: No i didn't shade the tree.
I hope it will get back to normal or at least that the curves decrease. I tried to stake them to small chopsticks but it was difficult to keep them in place and i was affraid to break them, so i left them as they are.
Edit : I couldn't keep myself from figuring out how to realign those branches, and i found the idea of rolling small rectangles of relatiely hard paper on them , i could thus adjust each "tube" to the height desired. I hope they will not bake inside in the heat of the morning (white paper + openings in the bottom and the top, i hope this will reduce the baking).

Dear all,
My mango seedling (unknown variety) has suddenly this strange flush (the previous flushes in the season were normal), but the current one, the shoots seem to get curved since the past three days. Could it be the extreme heat wave in my city of the past 3 days (over 100F) that makes them curve like this? I am watering it each 3 days. The soil is clay and still moist under the top layer between the waterings








Here is a picture of the whole tree 5 days ago before the flushes started curving):

No decomposable ammendment is likely to improve planting holes for mangos--- way likelier to sicken.

What about the compost for mango trees, can we use it as a mulch? if not is it beneficial for 3 feet seedlings to till it around the tree?
Thank you in advance for the answer

Hey guys, I'm curious if Valencia Pride is usually this late in the season for SoCal. My tree didn't set fruit the first two flowerings this year due to what seems like bad water management on my part. A little cold snap later in the season cause a little bit of flowering and it hung on to one fruit with my revised watering schedule.

But this fruit is on the tree and no hint of yellow to it this far. I'm not complaining just wondering if it is typical.




Hi Victoria Ave,
Can you elaborate a little bit on the bad water management that led the tree not setting fruit and the revised watering schedule that resolved the problem? Thanks

Tropical Fruit Discussion / Spraying copper after pruning mango : Immediately?
« on: July 09, 2020, 11:22:47 AM »
Dear all,
I am going to remove the end of a mango branch that i suspect has a fungal disease, and i read that spraying copper on the cut can help preventthe spread.
My question is : do we spray immediately after cutting or do we wait till the wound dries a little bit ?
Thanks in advance

Hi guys, this year i decided to bag my guava fruits to protect them from fruit flies.
I am wondering at which development stage should i bag them (currently the tree is flowering and some flowers are setting fruits).
Thank you

You don't have to translate paragraphe by paragraphe, you Can simply copy the link of the original website in the left case of Google translator (as if you want to translate thé link), then click on "translated" link that appears in the right case. Thé website should appears in the translated language.

That infection is all the way to the cambium layer, so it is not just superficial.  You did well to prune.  I hope you sanitized your clippers after cutting into the infected area.
Ah ok, thank you for the clarification and for your initial advice.
I cut the whole branch from the base as the first cut in order to avoid spreading any infection. then i started to explore the cut branch and take the pics away from the tree. And yes i sanitized the clippers afterwards as well for future utilizations.
Best regards

Hi all, today i cut the branch and i share here more detailed pics of the inside of the branch (a cut at the injured portion), may be it will be useful to future readers.
Apparently the black spot was limited to the bark. It also did not extend to an area out of the visible black spot. I cut the branch at the base and it was clean.
@ Oolie: I hope that the infection that killed your tree was more extended than my case (sorry for the loss by the way)

Hi all, i noticed a black spot on a branch of my mango seedling (unknown cultivar). The spot is exactly on the same area where there was a contact with a leaf from a second branch (the leaf was stuck against the nearby branch at a leaf node so when i displaced the leaf i found the spot and the leaf node fell, as if the prolonged contact and humidity enduced the black spot, but i am not sure if it is the case or juste a coincidence).

Should i worry about this spot? in that case should i cut the whole branch to avoid spreading to the whole tree (it is the smaller one of the 2 future main scaffold branches,the one oriented to the right).
If there is no worry about it i will leave the branch.

Here are some pics with a closeup on the spot :

We like to vet the seedlings through one winter whenever possible. Some seedlings are just inherently weaker or more prone to disease and by grafting seedlings that have gone through a SoCal Winter, we are able to weed out the weaker stock.

I’ve also had great luck with direct seeding mango seeds into the ground. These are usually very vigorous because there is not transplant shock. I sometimes go against my own advice and graft them when they are too small because i have scions available and don’t want to toss the scions.

The good thing about starting them in pots is that you can move them into your garage or greenhouse in Winter and you can also root prune your trees to create a more dense root system.

Simon

Interesting thread and detailed explanations, even though i am in a different country, but a mediterranean one (Tunisia) so i guess the climate is similar to yours.
When you seed directly in the ground, do you protect / shade the young seedling during the first week when it emerges in order to prevent hot sun damage on the young leaves?

Tropical Fruit Discussion / Re: dechlorinated water for jaboticaba
« on: May 17, 2020, 03:40:32 PM »
Thanks for the addditional information.
I am wondering, which has the most damaging effect on the plants in tap water : Chlorine or excessive TDS (or salts)
Let's say if the total damage of the tap water is 100 %, how much each factor has , 50/50? 25/75?
I know the answer cannot be accurate, but i am wondering if removing the chlorine from tap water can be an acceptable alternative to collected rain water.

You don't need any lemon. Left outside, sun or no sun the chlorine dissipates into the air. Though sunshine and heat will accelerate the process. One day's exposure will do the trick.
Do you need to stir the water during the day (especially if it is in a deep barrel) or it will dissipate even without beeing stirred ?

Thank you very much for your replies. I have a seedling planted last year from a seed (unknown variety) and it is starting pushing growth right now, that is why i wanted to know the good practices. If i get 1/4 of your results i would be glad.

Impressive growth in two years Vernmented. Congratulations
Does it need frequent watering to have such result?
Do you have pictures of its evolution? (first 6 months, after one year...) to understand how was the path to reach this impressive result.

You should also  mulch around it with organic matter i think. Your soil doesn't seem to retain water. Mulch will help improve it.

Thank you for the answers.  I ll look for this kind of bags. The appropriate size for guavas is 6x9 inches?

Thank you for your comments.
@Garden_Harley_FL : By problems i mean my guava fruits are infested by fruit fly larvae. That is why i was hoping that frogs can eat the first generations of fruits flies before the fruit set.

Tropical Fruit Discussion / Frogs and toads : Are they efficient to control fruit flies in a garden?
« on: April 21, 2020, 01:32:11 PM »
Hi all. I noticed two frogs in my garden the other day, and i was wondering whether frogs can be a solution to combat fruit flies (i saw in the net that frog breeders feed fruit flies to their frogs but i don't know if it is relevant in case of combating a fruit fly at the scale of a garden). I have 3 guava trees and i had problems of fruit flies in my guavas the past two years. If this can be a solution, i will try to attract more frogs in the garden.
Apperently a frog can eat 100 insects / night, 10000 / season. I t can be intersting if the fruit flies are reachable to it in the ground.

Tropical Fruit Discussion / Re: Tipping Cacao seedling - same as mangoes?
« on: April 18, 2020, 08:56:39 PM »
Thank you Peter and TomekK for your answers.
I forgot to mention that the two seedling are in a pot, and i plan to keep them potted inside. Actually they grew in the same pot and i didn't separate them.
Currently , the top 4 or 5 inches are new growth (still green) and below is woody, is it better to cut just the tip to induce branching from green part or to at the woody level?

Hi all. I have 2 cacao seedlings which are 3 feet tall but didn't branch out. I am wondering if i should remove the tips to induce branching like it is the case for mangoes.

My (now) 7-year-old Pickering bore 35 fruit last year. It starts out with many more, but most drop off. It's under 5 feet tall. It's in the ground, though, and not in a pot.
Do you have a picture of the tree? the saffold branches must be very low if your tree is 5 feet tall.

I am a professional plant propagator in the central Florida area, and have rooted over 250k guava cuttings since 2016.  From a personal standpoint, I have tried a bunch of cultivars, and will never have a guava tree in my yard.  Total waste of planting space.

Why do you consider a guava tree as total waste of planting space? for the difficulty of fighting fruit fly infestation? or are there other points you are thinking of?
