Prune lightly in early spring by cutting out weak growth, but save as much old growth as possible. For a spectacular summer display, cut the entire plant back to 2-4 feet in the spring. You will sacrifice your spring blooms by using this method, but you'll get a striking summer show.
Here's an idea for those summer shrubs such as forsythia that are spectacular in spring but a bit boring the rest of the year: Plant clematis vines under the shrub. The clematis will add a bright burst of bright summer color to your otherwise dull spring shrub, and the clematis will thrive with a little shade on the roots during the heat of summer.
- Mulch well to keep the roots cool
