I purchased a weigela florida rumba bush this past spring. I've gotten mixed responses as to when this shrub should be pruned since it blooms from June through September. Some say to prune after blooming and others say to wait until winter. What's the true story on when to prune this shrub?

This shrub produces the main bloom flush in the spring and then blooms sporadically through the summer. In my experience, it is best to remove several of the oldest stems each spring, by cutting them at the base of the plant, immediately after blooming. This promotes vigorous new growth and also allows you to enjoy the best possible spring bloom show. Alternatively, you could cut the entire plant off near the ground about every fifth year as a more drastic "renewal" type of pruning. Since yours is a new plant, you might not need to do much pruning until about three years from now when it has begun to show signs of woodiness. Each summer you may also prune lightly, removing a wayward tip her or there as needed for shape. Dead or damaged wood can of course be removed at any time.
