Lavender

Overview

English lavender is a Mediterranean subshrub with aromatic gray-green foliage and summer flower spikes. It needs a different watering rhythm from moisture-loving mint.

Humidity, heavy clay and mulch piled against the crown are common reasons plants decline. A raised mound or gritty container mix is often safer than amending a wet hole.

Growing conditions at a glance

Life cycle

Short-lived evergreen perennial shrub

USDA zones

Typically USDA zones 5–9, depending on cultivar and winter moisture

Sun

Full sun, ideally 6–8 hours

Soil

Lean, gritty, very well-drained soil; avoid heavy wet clay

Soil pH

Neutral to alkaline, roughly 6.5–8.0

Water

Water deeply, then allow the mix to dry substantially; established plants dislike frequent shallow watering

Spacing

18–30 inches, allowing air around the mature mound

Germination

Often 14–28 days after a moist cold period; germination can be uneven

How to plant lavender

1. Choose the sunniest, fastest-draining site available.
2. Plant the crown slightly high rather than in a basin.
3. Keep organic mulch away from the woody base; use gravel where appropriate.

Growing from seed

• Cold-stratify seed according to the supplier's directions.
• Sow shallowly in a sterile mix and provide bright light after emergence.
• Expect slower, less uniform growth than with cuttings or nursery starts.

Growing in containers

Use a pot only slightly larger than the root ball, a fast-draining mix and unrestricted drainage holes. Terracotta can help the mix dry between waterings.

Harvest, dry and store

Harvest

Cut flower stems when several buds have opened but before the spike is fully spent. Leave green foliage below the cut.

Drying

Tie small bundles and hang in a dark, dry, ventilated room. Large bunches trap moisture.

Storage

Keep dried flower buds in an airtight container away from light. Label culinary and craft material separately.
