Root Pruning Dogwoods and Sambucus
I recently met with a local master gardener who suggested moving two variegated red twig dogwoods, a weigelia, and a large Sambucus. She suggested root pruning first but I failed to ask about the timing on this. I have read that root pruning should take place months before moving the bush, but it doesn't seem like a good idea to do that during the hottest month of the year. If I root prune in Sept, that only gives me a month until I have to actually move the bushes. Any advice on this issue would be appreciated.
