My fuyu still has green leaves in zone 7 no color change yet, but the weather is still unusually warm for autumn. It's true that persimmons will drop leaves and leave the fruit hanging on the tree so don't worry. It reminds me of Charlie Brown's christmas tree when you have just branches and fruit hanging on them lol.
yeah i am not worried about them hanging, but just wondering how long should i let them hang on. I know usually people let them hang ,but i have seen it in the warmer parts of the country where they may not get hard early frosts, i am living in a somewhat mountainous area (830m above sea level) and the fruit may not manage to turn colour all arround in time.
You should move your potted persimmon in the dirt so the roots will not dry on the bottom so quickly. Also if you move the pot so it is sitting on the dirt instead on concrete it will allow some small roots to escape and it will help keep the plant healthier.
Actually the problematic part of the pots soil level were both the top and the bottom, the top probably being on the drier side,the bottom was the opposite, being too wet, especially on the plant that shed its leaves green. I had read that any water stres when the plants are holding fruit may result in the fruit falling, so i technically overcared them in a way, i will fix the water rejimen next year, the last week being rain every day surely didnt help with the condition also.
I had planted them in spring in the ground ,but after a few nights with hard frosts most of the buds beggining from the middle of the plant going up were damaged and dead ,so i decided to move them back in the pots since i thought atm that this will be happening every year.
