Answer: Although 'Wine and Roses' is usually a low-maintenance plant, and attracts hummingbirds and butterflies, it does require pruning to maintain an attractive, dense shape. Weigela is a spring bloomer, and blooms on old wood, so it should be pruned immediately after blooming (late spring). You can choose to lightly or heavily prune, and the weigela will recover nicely in either case, although heavy pruning will, of course, result in a smaller shrub for the following growing season.
Some points to remember in pruning are:
- Be sure to use clean pruning shears, so as not to spread disease.
- Remove dead, diseased, damaged, or dangerous branches at any time of year.
- Pruning cuts should angle outwards--slightly, just above an outward growing bud.
- If you want to renew an older shrub, prune the oldest branches down to the ground, but don't remove more that about one-third of the shrub each year.
- Follow the natural shape of the shrub; in this case, a fountain shape.
