Pruning persicaria orientalis — FAQ
When should I prune persicaria orientalis?
End of season, after seed set if self-sowing is wanted. No in-season pruning is necessary for this vigorous annual. Deadhead individual racemes if you want a tidier appearance, or leave them to self-seed. At the end of autumn, cut plants to the ground and compost the stems.
How often does persicaria orientalis need pruning?
As needed (deadheading optional); remove at season's end. Persicaria orientalis (kiss-me-over-the-garden-gate) is a tall annual, so there is no overwintering pruning. Deadheading is optional — removing spent flower racemes slightly tidies the plant but reduces self-seeding if you rely on it to self-sow. Simply cut the whole plant back and compost it at the end of the season after collecting seed if desired.
