About a year ago I planted a few Gold star Potentilla. They looked fine over the summer months but now many of the stems appear brown and look like they're dying. Should they be trimmed? Any help would be appreciated. |
Potentilla tends to get leggy with age so the best approach is to prune out some of the oldest stems in late winter or early spring before new growth appears. It's too late in the season to do any pruning now - pruning encourages new growth and that new growth won't have a chance to harden off before your first frost. Wait until early spring to prune it back. Enjoy your garden! |
