I live in LaBelle, Fl and have been trying to grow peaches for a few years. I have a tropic beauty, Fl glow, Fl snow, grande, prince and Fl one. Some I had for 5 years and a couple are under 2 years old.
Ideally the days are getting shorter and they should have lost their leaves and should be getting chill hours. So far this year we got down to 67F one night and some of my trees are flushing new growth while a few are flowering but none have loss a leaf let alone had a chill hour. UF is in Gainesville and their peaches and blueberries are always going to perform better in North Florida. My trees flowered throughout the summer and some even set fruit. I believe this is due to heat stress not proper chill hours. The fruit fell off prematurely if I didn't yank it off first. Last year I had good fruit set and we had a 30F night in the end of February and some of the trees dropped their half developed fruit. One year a squirrel picked the immature fruit and took one bite out of each one before he dropped it on the ground. He got 30 fruits in one day. RIP squirrel!
But not all bad. One day my son and I walked out in my yard in March and their was a perfect looking Prince peach on a tree. I bit into that peach and I have never tasted a peach that good in my life. I handed to my son to try and he didn't give it back. He still talks about that damn peach!
My tropic beauty had about 50 good peaches the past 2 years and it had a real growth spurt this past summer. I don't have any squirrels left in my yard and I walk out every morning without my son. Now my only problem is the bugs. The peaches taste the best if they ripen on the tree. The stink bugs like to poke the peaches and the ants and beetles can destroy a peach in one day. I tell you once you eat them you are hooked. Georgia peaches are so inferior!
The trees love fertilizer and grow fast. I think they only live around 12 years. Pump them and if you have room try a couple varieties. So far Tropic Beauty has been my best producer but the Fl glow and Fl snow and prince taste better. I don't think they will ever lose their leaves and get enough chill hours by December 21st like they were designed. The further up north you go the more consistant the results.
I got a Grande this year, I think they only need 50 chill hours. I have never tasted one though. I got a
Fl snow 2 years ago and it was a small tree from Hopkins nursury. It had 50 fruits the first year and man they were good! This past year it didn't produce any. Depending on who you listen to they require 200 +
hours? Hopkins is south of Immokalee and warmer then me. I would guess they hit their trees with blooms plus to induce fruiting to help sell them but I haven't tried it yet?
