Lavender plants are generally easy to care for. Learn how to create a fragrant and beautiful lavender hedge, and maintain it for years to come.
The perfume from a lavender hedge is without equal, while the beautiful purple flowers attract scores of bees and butterflies in summer. The strongest scent is released when the flowers are brushed, so plant your hedge where you can run your fingers through the stems as you pass.
When to Plant: Spring
At Its Best: Summer
Time to Complete: 2 hours
A month or two before planting your hedge, dig plenty of organic matter into the soil to improve drainage.
In spring, buy small plants and make holes at 12-inch intervals, or dig out a long trench. The plants won't require additional fertilizer at this stage. Plant so they are at the same level as they were in their pots.
In heavier, clay-rich soil, plant the lavenders slightly above the soil surface, and draw up soil around the root ball to encourage water to drain away from the base of the plant. Firm in around the plants with your fingers.
Water the plants well. Although lavenders are very drought-tolerant, they will need to be watered for the first growing season until they are fully established. In spring, apply an all-purpose liquid fertilizer to the plants.
Although lavenders are generally easy plants, requiring little or no additional watering once established, they do need annual care. Leave small, young plants unpruned for the first 12 months after planting to allow them to put on some growth, but in subsequent years cut your hedge twice a year to prevent it becoming leggy.
When to Start: Late summer, after flowering, and early spring
Time to Complete: 1 hour or longer depending on hedge size

To keep your lavender plants young, bushy and healthy, cut them back in late winter or early spring. Clean your tools thoroughly and spray them with a household disinfectant before you begin work. Then, using sharp shears, cut the stems back as close as possible to the old wood.
Take care not to cut into old brown wood, since the plants will not produce new shoots from this. Shear to a few healthy leaves above the brown stems, and work systematically along the hedge, keeping it as level as possible.
In late spring or early summer, the sheared plants will grow an abundance of side shoots to create a compact, bushy hedge. To keep it neat, cut it back again after flowering in late summer — remove all the old flowerheads to prevent the plants from putting their energy into making unwanted seed.
