Start indoors 6 to 8 weeks before last frost, and transplant out or direct so in late March to mid-April.
Barely cover the tiny seeds. Use a sterilized potting soil, and keep watering to an absolute minimum – just enough to keep the medium from drying out. Germination takes 10-14 days. Once seedlings are large enough to handle, transplant at a spacing of 45cm (18″) into the garden.
Choose a shady spot or a location where plants can be protected from midday sun. Lemon balm prefers a fertile, moist soil in a cooler part of the garden. Plants grown in partial shade will be larger and more succulent than those exposed to full sun.
