400 chill hours in California is a far cry from 400 chill hours in the Gulf Coast. Join the Texas Fruiting Plant group on Facebook. Growing cherries on Gulf Coast has been discussed many times. No one got any cherries and trees died in the summer heat.
" I’ve grown and fruited the bush cherries Jan, JOEL, and Joy. About 15-20 years ago.
They are hybrids were developed by Dr. Meador in New Hampshire.
Fruit quality is poor, like a bad pie cherry. I ripped mine out.
Tried all the low chill cherries over the years. None bore fruit.
Grew Katy ; Goldkist Apricot and maybe two fruits a year. Ripped them out.
Matagorda County, coastal Texas zone 9."
“Trialed Minnie Royal and Royal Lee for 4 years…they looked great every spring, suffered every summer and went dormant early every fall. The most cherries ever produced was 6. They simply can not take the heat and humidity of the Houston area. They do better with the heat if there’s little to no humidity”
