July to sharp frosts
Hardy, perennial bushy herb, Lemon Balm is noted for its strong lemon aroma. Height to 50cm.
March to May, in pots or trays on the surface of barely moist seed compost and cover seeds with a sprinkling of finely sieved compost. Place in a propagator at 20-25C until germination, which takes up to 21 days.
Transplant seedlings to small pots or cells until large enough to plant outdoors. Plant 30cm apart in full sun, once frost risk has passed.
Protect plants over winter with a mulch of compost or leaf mould. Plants should survive for several years.
Infuse leaves in hot water for a herbal balm tea.
