Q.Smoke tree shape
I just bought a smoke tree that has been trained more like a shrub. Can I stake it to try to get it retrained?
Don't do much trimming this first year. The plant needs to establish good roots. It needs energy for that and energy comes from the leaves. Here is another article for you. https://www.gardeningknowhow.com/ornamental/trees/smoke-tree/pruning-smoke-trees.htm
The plant is actually displaying its natural growth pattern.
