Fruit drop can be from several reasons.
Weather, pollination, pests, disease or overbearing.

This sounds like it could be a few different possibilities. A photo will help me to see the issue, and better help me to recommend a solution.

The first thing to check will be nutrient levels. Deficiencies in magnesium, calcium, potassium, and phosphorus can all show these symptoms.

Next, will be fungal issues. Do leaves, or branches also have spots that are black or brown, or maybe rusty looking stuff on the leaves? This could indicate a fungal infection.

Applying dolomitic lime and wettable sulfur together can help kill off an infection, as well as supplement sulfur, calcium and magnesium for fruit formation.

Applying a fruit tree fertilizer once or twice per year will help keep the tree healthy, and ensure that there are plenty of nutrients in the soil.

Q. I have a 2 year old with 7 months Soursop tree. I live in Houston Texas. Iโ€™m a little sad cause temperature drop to 43 degrees F

for 3 days and all the leaves had fallen. After the third day it warmed up to 75 degrees and I built a 10 foot tall greenhouse f or future frost. Can someone please tell me if my soursop will survive or die ? I grew this soursop tree from seed in a 55 gallon plastic barrel and itโ€™s about 4 feet tall.

The 55 gallon barrel does has good drainage and I fertilizes every 3 months. So it was probably the 3 day rain that made my soursop leaves fall plus the wind at 43 degrees F. So maybe there is a chance that my soursop might survive ?

43 degrees in not a frost, so freezing can be ruled out. Soursop is evergreen, so a cold snap should not cause leaf drop.

I suspect a water management issue, too much or too little. Does the 55 gal drum have a solid bottom, or does it have ample drainage holes in the bottom? If not, root rot could be to blame.

Is the soil porous and drains fast? If so then water deficit/drought stress could be the cause of leaf drop.

Do you fertilize? If not, then nutrient deficiency could cause susceptibility to environmental stress.

Q. Leaf concern

Why are my soursop tree leaves brown? Should I be fertilizing my soursop with a particular fertilizer?

That is a rather serious fungal/bacterial infection. Apply wettable sulfur to the area. This will kill the infection from the soil. The old affected growth will not recover, but you will know that the treatment is working when the new growth come in clean.

Q. SOURSOP

We grow soursop in Grenada. We have been transporting it from Grenada to Los Angeles,CA via air. The transit in total is about 3 days. The problem were having is that days later the fruit becomes black and hard as a rock. Any suggestion as why this occurs?

Plane Storage can bring about some rather extreme conditions. It may be that the fruit is freezing while on the plane, which would cause it to shrivel. This would have to be my guess. If you can send pictures, maybe I can see something that might tell me what's going on.

Soursop is a tropical tree and normally would not be suitable for the London temperate climate. If you have a garden that is somehow protected from the coldest temperatures, then maybe there could be an exception.

I'm providing links to 2 articles on soursop. I hope they answer your questions. Soursop is unlikely to produce fruit the first 3-5 years. It appears to be solidly tropical. It will not survive frost. You might lug it inside every winter and provide artificial lighting. Here's how.

Q. How to harvest leaves

How old should a soursop tree be before harvesting the leaves?

Answered by

You can do this as young as 2 years. If you are pruning or shaping the tree anyways, then what you cut off can be used. It is best not to take more than 1/3 of the tree or its leaves at one time, though.
