I planted six Oakleaf Holly bushes in November 2020. They were container grown and unfortunately very pot-bound. I performed some serious root pruning before planting into the earth. (This was before I'd done some research into the issues present in container-grown trees and shrubs.)
Fast forward to June 2021. The bushes are alive and showing some new green growth, some more than others.
I'm curious — does the fact that the bushes are growing above ground imply that they're also setting new roots? Also to note, when I tug on the trunk upwards, they feel strongly anchored in.
