My Flowering Avocado Turned Yellowish And Leaves Dropped

Question

I have 5 avo trees. One dead after it was flowering and have small fruitlets. The leaves turned yellow n dropped, after sometime the tree was dead. Now another one is bearing lots of flowers and fruitlets, and it is dying like the first one. The rest of the trees are very healthy with dark green leaves. But with no flowers. What could be the problem? Is it root rot(its on a slope) or fungal attack? Please help! Thank you.

Answer 1

It looks like they are planted too close together, which can affect sunlight and air flow. Light pruning will help. Anthracnose is a fungal problem that is a possibility. Here are cultural tips you can compare with your growing conditions, such as fertilization and watering, as well as pest and disease issues:
