Water newly planted Topped Lavender regularly until established, typically for the first growing season. Once established, it is highly drought-tolerant and prefers infrequent, deep watering.

Allow the soil to dry out completely between waterings to prevent root rot, especially in humid climates. Reduce watering significantly in winter.

Prune Topped Lavender after its main flush of flowers, typically in late spring or early summer, to encourage a second bloom and maintain a compact shape.

Remove spent flower stalks and trim back about one-third of the current year's growth. Avoid cutting into old, woody stems, as this can inhibit new growth.

Topped Lavender can be propagated from semi-hardwood cuttings taken in late summer or early autumn. Select healthy, non-flowering stems about 10-15 cm long, remove lower leaves, and dip the cut end in rooting hormone.

Plant in a well-draining potting mix and keep moist until roots develop.

Repot container-grown Topped Lavender every 2-3 years, or when it becomes root-bound. Choose a pot only slightly larger than the previous one, ensuring it has excellent drainage. Use a well-draining, gritty potting mix.

Repot in early spring before new growth begins, being careful not to disturb the roots excessively.
