How to prune agastache 'kudos coral'

Deadhead throughout summer; cut back hard in early spring before new growth emerges. Deadhead spent flower spikes by cutting back to the next lateral bud or leaf node during the season. In early spring, cut all stems down to 5–10 cm (2–4 in) above the base to stimulate fresh growth.

Deadhead regularly through the flowering season; hard prune once annually in early spring. Agastache 'Kudos Coral' benefits from regular deadheading to extend its long summer bloom season and a hard cut-back in early spring to encourage vigorous new growth. Cutting back stems after flowering also prevents excessive self-seeding and keeps the plant tidy through winter.
