What causes oranges to be dry?
I have several orange trees and all of them produced some fruit that is dry. Some trees had all of their fruit dry inside. This is only my second fruit season in this house, having moved in last fall. Last fall the fruit was fine.
We did not have a drought this summer and I water regularly. Additional consideration is:
My "soil" is pretty much non existant. I live in SW Florida and all I have is sand.
My well water is very alkaline. Sometimes tree branches that get hit directly by a sprinkler die.
I fertilize regularly. I wonder if this is the problem. Someone once told me not to fertilize in the fall because it would dry the fruit out. This same person gave me other bad advice, so I don't know what all to believe.
So the questions are: What causes orange and tangerine trees to produce dry fruit?
If it is fertilizer, when should I fertilize?
Thanks for any help.
