How to grow rosemary

Rosemary is best grown from plants or from rooted cuttings, taken in the summer from 7cm long shoots. It is possible to grow rosemary from seed sown in spring but it can take up to two years before you're able to harvest it.

Choose well drained soil in a sunny sheltered site.

Keep your rosemary plant watered until it has established. Remove any frost-damaged growth.

Rosemary is a perennial herb so will crop year after year.

Harvesting and using rosemary

Pick leaves for use fresh. In very cold areas you may need to protect rosemary plants with horticultural fleece over the winter or move container grown plants indoors.

Rosemary flowers are also edible and are loved by pollinating insects.
