Our zone is 8a/8b. We have 2 south facing patios that become ovenlike and basically useless in summer. Removing the patios or constructing shade structures is not possible for the foreseeable future.
Wondering if there are any shade trees that can be grown in very large pots that would reach decent size (15-20 feet) enough to cast some shade on the patio and house. They would need to be:
Hardy in Zone 8a outdoors in large pots (rarely get sustained temperatures below 25 degrees)
Tolerate a lot of rain in winter and a high number of chilling hours
Tolerate high heat in summer (90s-100s)
Good canopy spread and shade quality
Able to reach 15-18 feet tall in a pot with room to walk under
Yield of fruit or nuts would be nice but not at all a requirement
Preferably fast growing
I don’t ask for much do I??
I guess an air pruning pot would be my best bet for healthy roots and height of the tree, something like this:
Off the top of my head my ideas are jujube, chestnut, heartnut, pecan, I don’t know how big these larger trees would get in a large air pruning pot
I searched the forum and saw @GreenFist has trees in 40 gallon fabric smart pots, if you see this I would love to know which trees you’ve got, do you get sustained high temperatures in your climate in summer and is it dry or humid, and how big your trees have gotten.
