I wrote about some trees I have that have done very well in a large pot in the yard. And they continue to do well but the pot has limits. My pomegranate trees always seem to get so heat stressed in their large pot. I drove past a good size pomegranate tree today that was full of leaves and fruit. So for them I think I will plant them this fall. Fall is the best time to plant trees.
My dwarf citrus do fair but they tend to get colder in the pots during the winter and I have lost several. My two grapefruits are still struggling to come back after a good freeze two winters ago.
