We live right off 281 south and west of the Guadalupe River bridge, We've had right at 4 inches of rain in the last 6 days. Woke Sunday morning and one of the persimmons in the back had dropped 90% of it's leaves. The fruit is still hanging on. Other's are OK. WTH? On a side note I don't know if I should be happy or sad.....

I would not get too worried about that yet. I have several and I have seen them drop leaves at odd times that I swore they were dead but every time they sprout new leaves and seem to come back more robust than ever. I just had one go through this again about 3 weeks ago.
