Hi. I used to prune my spirea, potentilla, etc (summer flowering shrubs) in late Feb. The past couple years, tho, they've been buried in snow. So I pruned them late last year (March), and they put up all kinds of sucker growth and were just leggy and weird all season. Coincidence? Or was that from all the water we got?
I wonder if I should dig them out of the snow to prune them! Or prune in November next time maybe? Thanks.
