Water French Lavender thoroughly when the top 5 cm of soil feels dry. Allow the soil to dry out between waterings, as overwatering can lead to root rot.

Reduce watering significantly during cooler months to prevent waterlogged conditions. Ensure good drainage to avoid moisture buildup.

Prune French Lavender in spring after the last frost or in early autumn after flowering. Cut back about one-third of the plant's growth to maintain a compact shape and encourage bushier growth.

Remove dead or damaged stems and spent flower spikes to promote new blooms and a tidy appearance.

French Lavender can be propagated from semi-hardwood cuttings taken in late spring or early summer. Select healthy stems, cut them to about 10-15 cm, remove lower leaves, and dip in rooting hormone.

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

Repot young plants annually or every two years in spring. Choose a pot that is only slightly larger than the current one and ensure it has excellent drainage holes. Use a sandy, well-draining potting mix.

Overpotting can lead to waterlogged soil and root issues.
