First off, I'm not quite sure what kind of avocado tree it is. The tree is tall and slender (maybe 15 feet now). The avocados are kind of long shaped and some are turning black, but I haven't seen the skin wrinkle yet.

Two months or so ago, the tree was shedding a lot of leaves and the branches were turning yellow. Then the branches started drooping and some turned black and dried up. I went to Home Depot and grabbed some avocado and citrus feed. This seemed to have stopped the shedding a bit, but the yellow branches are still droopy.

The rest of the tree on the higher parts looked good though. The leaves are very green. The problem that I am seeing is that there's lots of avocados that are green and maybe two to three inches long that are dropping on the ground. Some of them have scars on them. I looked on the tree and there are some avocados that turned black and seem to be ripening, but I see that they are cracking, revealing the green flesh inside.

I'm not sure what this means, but it doesn't seem good. Can someone please help!?

Could you post some pictures? That usually will speed up the solution process. If not get ahold of your local Extension office and talk with a Master Gardener. They will probably need to come out and look at your issue. Identify where you are from in case your problem is regional and problematic for avocados where you live.

It sounds as if you have an Anthracnose problem. This is a fungus that is only treatable with a fungicide. You appear to be past the prime application period which is usually when the tree starts to get fruit in early summer late spring. Again contact your local Extension office for fungicides that work in you area.

Your leaves indicate salt burn or fertilizer burn (commercial fertilizers are salts) from not watering deep/thorough enough. This incorrect watering in combination of hot dry winds could cause your fruit cracking.

Nice Pics. Just like I suspected it looks like Anthracnose. Being from LA you have a lot of resources through the Ag Extensions at local Universities. Check it out. Here a good starting point.

crap...thanks for looking into this for me. I was kind of busy the past few weeks. Last week I forgot to water and all my avocados fell...I am so bad at this.

I generally water twice a week and hose it until the soil is drenched. Probably have the hose on (pretty good water flow) for 5 minutes or so. Should that be enough?

I'll probably get some pesticide at the end of the season and spray it on. Hopefully it'll look better next year. Just to make sure, should I be spraying it all over the tree as in the trunk, the roots, the branches and leaves?

Thanks for all the advice!
