I am looking to grow a tree to have some shade on my roof in the summer. I can only plant it in a pot (not in ground), it will be a 20 gallon pot.
Can you give me a suggestion which tree to grow? It gets very hot weather full sun 42c (107F) here. It should give shade at least 4 feet around it.
Would love if it is a fruit tree, but not necessary.
One idea I already have is Fig. But I already have a fig tree, and want something new.
