Growing Lavender: A Care Guide for a Fragrant, Low-Maintenance Plant

Lavender is one of the most forgiving perennials you can grow, provided it has the one thing it truly demands: sharp drainage. Get that right, and it will reward you with years of fragrant flowers and very little fuss.

Choosing the Right Spot

Lavender needs full sun — at least six hours a day — and, above all, soil that drains quickly. It evolved in the rocky, sun-baked soils of the Mediterranean, and it struggles in heavy clay or anywhere water sits after rain.

If your soil is heavy clay

• Plant on a slight mound or raised bed rather than in a dip
• Work coarse grit or horticultural sand into the planting hole
• Consider growing in a pot with a very free-draining mix instead

Watering: Less Is More

Once established, lavender is drought-tolerant and prefers to dry out between waterings. Overwatering — not cold — is the most common way gardeners lose lavender plants, especially in the first year while roots are establishing.

Feeding

Lavender actually performs best in lean soil. Skip regular fertilizer; too much nitrogen produces soft, leafy growth at the expense of flowers and makes plants more prone to flopping and disease.

Pruning to Prevent Woodiness

The main long-term challenge with lavender is that it turns woody and sparse at the base after a few years if left unpruned. The fix is a firm annual prune.

How to prune

• Prune right after flowering, in late summer
• Cut back about one-third of the plant’s growth, shaping it into a rounded mound
• Never cut back hard into old, leafless wood — lavender rarely reshoots from bare stems

Winter Care

In most temperate climates, established lavender needs no winter protection. In very wet winters, good drainage matters even more than usual — waterlogged roots in cold, wet soil is the main risk, not the cold itself.
