I anticipated a bumper crop of pineapple guavas this year, as my 4-year old trees had dozens of big blossoms. Similarly, my cherimoya trees of similar age had dozens of blossoms that I had hand-pollinated with a small paint brush. And my 5-year old avocado tree had a number of flowers. Yet the guava produced NO fruit this summer, the cherimoyas less than a handful of fruit, and the avocado NO fruit. I water and fertilize regularly and the trees all seem healthy. I live near the beach in So. Cal, by the way. What's going on? Thank you!
The Guava and the Cherimoya will, most likely, be a problem with soil fertility! They are heavy feeders, and this means that they will require quite a bit of fertilization. These articles will help:

As for your avocado- This is going to require two trees. One for each flowering type. Here is an article that will help:

Thank you very much, Bush Doctor. Those links were relevant and quite helpful!
n the lower parts of branches. I have another feijoa that's growing in a similar sized pot and it is doing fine (no leaf-drop). O ne of the branches has lost nearly all of its leaves (except for one). Sometimes just touching the leaves cause them to drop. Stro ng winds have also damaged only a few leaves, but I don't think that's the actual problem. Is it some soil/watering issue or som ething? Would appreciate some help. Thanks There are adequate drainage holes on the bottom of the pot. Will the feijoa recover and grow back in those places where it has lost leaves? Quite worried about its health - looking a bit bare. I'm hoping it will make a nice bushy shrub. Also there seems to be some sort of insect pest that nibbles on the new young leaves, but I haven't seen the pest itself yet. Any suggestions on what it may be?
Here are some articles that should help with its care. Check the soil pH. If it's too high, it can cause yellowing leaves. It also needs light fertilization every other month. They don't need a lot of water, so you might be overwatering.
I've also included information about pest control. I would spray it with Bt and see if that helps deter the pests, which may be caterpillars.

I had 3 trees and my other 2 died the same way as the last one is turning. This one grew big within 6 month and it started drying out. Nothing changed with watering. It just starts drying and the dirt is not too wet and not too dry. I live in Central Florida, not much heat recently.
It sounds like an infection has taken over the soil! This can cause many trees and plants to fail when planted in this area.
I would recommend using a fungicide to help kill off the infection. You may even consider solarizing the soil.

I purchased 2 trees this year and they both had lots of blossoms, one was full excited to see so many flowers. It has been doing great we went on vacation and now it seems like they are falling off? Hardly any fruit. the other tree seems to be doing fine we did lose a few but not like the other tree, the fruit is growing its about 1/4 of inch. What I'm I doing wrong?
Unfortunately, these trees need regular watering. If you experienced any dry period at all, then this can be the cause. This one is self fertile, so it will not be the issue, here.
