Lavender is a spring and summer favourite for many UK gardeners because of its fragrant flowers and calming scent. But if your lavender plant has ever looked leggy, wilted, or failed to flower, the problem might be underfoot.
According to the Royal Horticultural Society (RHS), lavender’s success comes down to one crucial factor: the right soil. “Lavender is a Mediterranean plant and needs lots of sun and fast-draining soil,” the RHS explained. “It will not survive long in shady, damp or extremely cold conditions.” That means soil that holds too much water, particularly in winter, can quickly spell trouble for this otherwise low-maintenance shrub.
Most specifically, lavender prefers “chalky” and alkaline soils; refrain from planting in clay soil that is likely to become waterlogged over winter.
Chalky soil is common in southern parts of the UK and naturally drain well, but growing lavender in raised beds or containers where you can control the soil is a good idea.
Container-grown lavender thrives in a mix of potting compost and sand or grit, placed in a sunny spot.
Lavender loves full sun and open spaces – avoid shady corners or low-lying areas where water collects.
Good drainage paired with six to eight hours of direct sunlight is the perfect mixture for strong growth and rich blooms.
During the plant’s first summer, you will need to water the lavender plant on a regular basis.
Once established, lavender is drought-tolerant and relatively hands-off, apart from some occasional pruning to keep it tidy.
They’re not too fussy, so you won’t need to add fertiliser to the soil as these plants “don’t generally need feeding”.
Choose chalky, sandy, or alkaline soil and a sunny spot – and your lavender will thank you with a summer full of fragrant blooms.
If, however, if the lavender plant is rooted in wet or heavy soil, the roots can suffer and the plant will wilt.
Also note that by the winter, some lavender plants aren’t hardy and won’t survive the winter outside.
This is why it’s best to check the lavender plant label before purchasing and bringing it home to your garden.
