lemon grass

Propagate From An Existing PlantDepending on the source, you can purchase lemon grass seeds or potted seedlings. If you know someone who has a plant you can start your own from a bulb. Detach one or more bulbs from the host plant. Place the bulb end in a rooting hormone powder such as (Rootone) then plant in a pot filled with vermiculite, moist sand, or any seed starting material. Keep the medium moist but not soggy. Another method is to place the bulb end in a small container (such as a jar) of water and allow the bulb to root. Then transplant. If your "benefactor" is very generous you can divide a large "clump" of grass. Pot and keep moist until you seen new growth. Then move to the garden.
Germinate SeedMorgan Thompson SeedSow from late January to March on the surface of a good seed compost just covering the seed with a thin layer of compost or vermiculite. Germination takes 21-40 days at 20-25C (70-75F). Sealing in a polyethylene bag after sowing is helpful. When large enough to handle, transplant the seedlings to boxes or 7.5cm (3in) pots. When well grown gradually acclimates to outdoor conditions and plant out in late spring 30cm (12in) apart after all risk of frost, in a warm, sheltered spot in full sun and moist, well drained soil. Keep well watered and give the occasional liquid feed. To over winter, lift in early autumn, pot up and grow through the winter in a greenhouse with a minimum winter temperature of 7C (45F). Keep well watered throughout the summer, just moist through the winter.
