How to Grow Lavender: Planting, Care, and Harvesting

Nov 03, 2026by David Schulze

Lavender is a beloved perennial herb, prized for its slender purple flower spikes, silvery-green foliage, and unmistakable fragrance. It is also a long-term project: lavender grown from seed germinates slowly and unevenly, and plants can take about three years to reach full size. The reward is a tough, drought-tolerant perennial that thrives in full sun and well-drained soil for years with minimal care.

When to Plant Lavender

Start lavender seeds indoors about eight to ten weeks before your last frost date, or sow directly in the garden once frost danger has passed and the ground has warmed. Transplant young plants into the garden in spring after the last frost, setting them at the same depth they grew in their containers.

How to Plant Lavender Seeds

Sow seeds about an eighth of an inch deep; they need some light to germinate, so do not bury them deeply. Keep the seed bed moist, and be patient, since germination can take two to four weeks and may be uneven. Choose a spot in full sun with light, well-drained soil. Give plants room for good air circulation: spacing recommendations vary by variety and source, from about twelve inches up to two feet or more between plants.

Caring for Lavender Plants

Water newly planted lavender regularly during its first year to help the roots establish. Once plants are established, they are very drought tolerant and need watering only when the soil has dried out; yellowing leaves can be a sign of overwatering, which leads to root and crown rot. Use drip irrigation or water at the soil level rather than overhead. Fertilizer is generally unnecessary and can cause excessive foliage at the expense of blooms.

Pruning Lavender

Timely pruning keeps lavender compact and productive. In spring, when new growth appears, remove dead or damaged stems down to the first set of green leaves. After flowering, you can prune off one-third to one-half of the plant to keep it tidy and possibly encourage a second bloom. Never cut into the leafless, woody part of the plant, because lavender does not readily produce new growth from old wood.

Harvesting Lavender

Flower stems can be cut at any time, and pruning as you harvest helps shape the plant. If you want to dry the flower heads, cut the stems when only a few florets are open. Dried lavender can be used around the home, and the flowers and leaves work in lavender-infused recipes such as tea or baked goods.

Frequently Asked Questions

Why is growing lavender from seed slow?

Lavender seed germination is naturally low and sporadic, and seedlings take a long time to reach transplant size, often six months or more. Plants grown from seed can also vary in growth habit and color, which is part of the charm for home gardeners.

How often should I water lavender?

Water regularly the first year while roots establish. After that, lavender is drought tolerant; water only when the first few inches of soil have dried out, and avoid keeping the ground soggy.

Why did my lavender turn woody and ugly?

Lavender left unpruned becomes woody and ungainly over time. Trim it annually just after flowering and avoid cutting into old woody stems, which do not sprout new growth.

Enjoying Lavender

Lavender fits beautifully into borders, herb gardens, and rock gardens, where its silver foliage and purple spikes look at home even when not in bloom. Harvest stems for fresh arrangements or drying, and try the flowers and leaves in kitchen recipes.
