How to prune begonia 'barkos'

Deadhead during bloom; cut back after the first flowering flush (typically late winter to early spring). Remove spent flowers at the stem base. Once flowering declines, cut all stems back by 50% to strong outward-facing buds, reduce watering, and allow a 6–8 week rest before resuming normal care to encourage rebloom.

Deadhead throughout bloom period; cut back once or twice annually after flush. Begonia 'Barkos' is a Rieger-type (hiemalis) begonia bred for winter flowering indoors. Deadhead spent blooms promptly to prevent botrytis. After the main flush, cut stems back by half to encourage a second flush. These are often treated as seasonal plants, but with a hard cut-back and rest they can rebloom.
