I’m getting 30 trident maples about 20” tall and I’m wanting to plant them in the ground. Some I want to make multi trunk trees and some separate to get 2-3” trunks. Is this a bad time to mess with roots to plant them over a tile in raised beds. They aren’t separate they are 3 to a pot. I live in central Illinois zone 5 some say I’m in zone 6. Advice needed. Thanks
