Abutilons have a tendency to become leggy and benefit form regular pruning to maintain compactness. Abutilons produce flowers on the current season's growth, so prune in late winter or early spring.
How do you prune leggy abutilon?
Major pruning should be done in early spring or late fall. Cut back branches selectively to shape the plant, making the cuts just above a node or on a strong, vigorous shoot near the plant's base.
When should I cut back my abutilon?
Especially when grown under glass, these vigorous plants will need a regular hard pruning in early spring to rejuvenate them and increase the amount of flower on the new growth in subsequent years.
