Agastache nepetoides

Germination

Sow indoors. Sow onto moist well-drained seed compost. Press seeds lightly into the soil but do not cover. Light is needed for germination. Propagate 18-20°C. Germination 14-28 days, but can be irregular and take up to 90 days. Water only from the base. Once germination begins admit air to prevent damping off. Once seedlings are large enough to handle transplant to 8cm pots. Acclimatise and plant out after danger of frost has passed with 50cm spacing.

Growing

Prefers full sun in any soil type that is free draining. Needs little attention. Water every week or two. May require staking in exposed conditions.

Cultivation

Cut back spent flowers to encourage a longer flowering window. This will self-seed freely so Deadhead early if you do not wish this to occur. May benefit from winter protection in the form of a mulch.
