Shaping Your Outdoors. Surpassing Expectations.
Post-bloom renewal pruning of forsythia to remove old canes, control size, and protect next spring’s golden flowers.
Forsythia delivers a burst of golden color in early spring, and it blooms on old wood, so pruning must happen right after the flowers fade to protect the following year's display. We renew the shrub by removing about a third of the oldest, thickest canes at ground level, which keeps the plant vigorous and prevents the tangled, overgrown mass forsythia becomes when neglected. We also cut back long, arching stems to shape the plant and thin crowded growth for better airflow. This renewal approach maintains a graceful fountain form rather than the sheared blob that sacrifices both flowers and natural beauty.
Protects next spring's golden blooms by pruning right after flowering; Renews the shrub by removing the oldest canes at the base; Prevents the tangled, overgrown habit of neglected plants; Maintains a graceful arching form instead of a sheared blob; Improves airflow and overall plant vigor
1) Prune immediately after the early-spring bloom fades; 2) Remove about a third of the oldest, thickest canes at ground level; 3) Cut back long, arching stems to shape the plant; 4) Thin crowded interior growth for airflow; 5) Preserve the natural fountain form and clear debris
Size and age of the forsythia and number of old canes; Degree of overgrowth and neglect; Whether staged renewal over several years is planned; Number of shrubs or hedge length; Debris disposal
In the PNW, prune forsythia right after its early-spring bloom fades so the plant has the full season to set buds for next year's flowers.
