I have a hebe that is overgrowing the other plants near it and I would like to remove it to another part of the garden. When is it possible to do this and what precautions should I take as I’d like to keep the plant just in a different spot! It is quite large . Also, I have a lavender bush that is going the same way and need similar advice .
Start new plants and remove the overgrown ones in time.
The hebe might recover from a hard pruning, but can die off, and lavender usually does not recover from hard pruning into old stems.
