How to prune begonia 'senator white'

Throughout the growing season (spring through autumn); cut back hard in early spring if overwintered indoors. Pinch or snip spent flower clusters back to the nearest leaf node. If plants become leggy, cut stems back by up to one-third just above a node to promote compact, bushy regrowth.

Deadhead every 1–2 weeks during bloom; hard cut-back once annually if overwintering. Begonia 'Senator White' benefits from regular deadheading and light pinching to stay bushy and flower-filled. Remove spent blooms at the base of their stem to prevent rot and extend flowering. Pinch back leggy stems by a third to encourage branching. This wax begonia blooms almost continuously, so grooming every couple of weeks keeps it tidy.
