Lavender care essentials
Plenty of Sunlight
Lavender thrives in at least six hours of direct sunlight daily.
Well-Drained Soil
Provides free-draining, sandy or chalky soil to prevent root rot. Avoid heavy, clay soils unless improved with grit.
Shelter from the Wind
Choose a spot protected from harsh winds to protect flower spikes and prevent drying out.
Annual Pruning
Trim spent flowers and tidy up after flowering to keep plants compact and healthy.
Lavender FAQs
Harvest lavender just as the buds begin to open, usually in early to mid-summer. For the best fragrance and oil, pick in the morning after the dew has dried. Cut flower stems regularly to encourage more blooms and prevent sprawling.
Choose a pot at least 30cm wide with drainage holes and fill it with gritty, free-draining compost such as a mix of John Innes No. 2 and coarse sand. Place the container in a sunny, sheltered spot and avoid waterlogging the roots.
Lavender prefers poor, low-nitrogen soils, so feeding is rarely necessary. In spring, you may apply a light handful of balanced slow-release fertiliser if growth seems weak, but avoid high-nitrogen feeds, which encourage soft, floppy growth.
Water well after planting, but once established, lavender is drought tolerant and only needs watering during extended dry spells. Overwatering can cause root rot. For container plants, water when the compost is dry to the touch.
