Forgot to mention, I am in the Southern California area (along the beach, Santa Monica) with high in the low 70's Fahrenheit. Thanks again!

Paleo,

Too much fertilzer will cause fruits drop. I do not fertilize my persimmon trees and just mulch them.

Hi Tony!
Thanks for the input but I haven't fertilized them in recent years. I did once or twice to my older tree several years ago but after the fruit dropped (very quickly) I read somewhere that fertilizing fruit trees while fruiting will cause them to drop so in subsequent years I stopped fertilizing altogether to prevent residual ferts causing the fruit to drop at a later time. Its been several years since then however. Also, the smaller tree that's all of the sudden started dropping fruit (when years before it would only drop a few) is now dropping 10 or more a day, despite the fruit getting larger each day. I'm really stumped. Anyone else have any ideas?

I should also clarify that at about the 3rd year it started producing fruit and I got quite a large crop of fruit (I mulched it with the shells of roasted sesame seeds that year, byproduct of sesame oil production, and had the biggest crop ever). After that bumper crop year, it started dropping more and more fruit each year until this year when it decided it didn't want to hang on to fruit and is dropping it in large bunches. If anyone else has any ideas it would be greatly appreciated.

Thanks for the tip. We did have a one or two foggy days, probably a 10 degree difference between the previous days, so that could be a possibility. My mom is now telling me she fertilized in April so maybe it was the fertilizer. Oh well, I guess I'll keep my fingers crossed and see that happens next year. If anyone has any ideas on how to keep them from dropping any further I'd love to hear them. I heard something like triple phosphate or green sand (what the heck is that?? lol) would help. Anyone?

I read an article in organic gardening years ago about monks beating the evil sprits out of orchard trees , they start older trees to begin to produce fruit again. I

have seen more than one perfectly healthy persimmon tree drop its fruit, I had one that did this every year one year it had only two left on the tree and my wife decided to weed wack around the tree when she pulled the trigger the end of the machine came up and damaged the trunk of the tree i got to eat the last two persimmons. I think the trees will drop fruit in favor of growth ,when life is threadened it will hold them, after that i would wack the base of the tree of the with a pvc pipe only once or twice , you can easily over do it, it will bruse the cambibum layer cutting back and threating the life. most greatest need is to reproduce. af after that when i saw them start to drop i would wack the tree and it would hold the fruit
