Forsythia is a true spring favorite and never disappoints with its shocking yellow blooms atop a mass of unruly branches. This early-flowering shrub can thrive for decades on neglect but there will come a time, whether out of want or necessity, that your forsythia will require pruning. But how can you do so without dampening the ferocious spring flame these spring shrubs produce?
Why Prune Forsythia?
When this shrub does so well without detailed care, why is it necessary to prune it at all? In many landscapes, if the shrub is properly sited, it may not need pruning. Unfortunately, many people underestimate the vigorous growth of these beauties, and in just a few years it may seem crowded and overgrown in a corner, narrow bed or border. A large, unruly forsythia may also seem overwhelming in a smaller space or when paired with less vigorous plants. Damage or illness may also create a misshapen or unbalanced plant that is no longer so pleasing to the eye. In these cases, judicious pruning can rejuvenate and refresh the shrub and give new life to its part of the landscape.
Rejuvenating an old, out of shape and poorly flowering forsythia is simple. After the shrub has finished flowering in late spring, cut all the branches back to within one foot of the ground. When branches put on new growth, reaching two feet from the ground, prune all branch tips to the first set of side shoots. This will help develop a fuller, thicker shrub for a more lush look. Be aware, however, that it will take until the second bloom season for a severely pruned forsythia to return to its former splendor.
A newer forsythia that is just a few years old can be kept in tip-top shape a bit more easily. Each spring, after it flowers, cut up to one-third of the branches back to the ground. Choose dead branches, branches thicker than your thumb and all crossed or inward facing branches. This will help create a good form with healthy air circulation and pleasing growth for years of beauty and enjoyment.
