How to grow
Lemongrass is frost sensitive, so in colder microclimates it may be convenient to grow it in a pot to bring inside during winter. In early spring cut the plants back to about a foot in height. Nurseries in Santa Clara County typically carry lemongrass, but you can also root your own from supermarket purchases.
- Type: Perennial, clumping grass
- Light: Full sun, tolerates partial shade
- Soil: Well drained. Fertilize regularly with nitrogen during growing season
- Water: Moderate; do not overwater to avoid root rot
- Size: 3–4' tall, 2–3' wide
When to plant/propagate
- Transplants: Set out transplants in spring after last frost date
- Cuttings: Best propagated by division in spring
- Harvest anytime during the growing season once the stalks are 1/2" in diameter
- Harvest stalks by using a sharp knife to cut as close to the root as possible, or by bending the stalk and twisting. You may wish to wear gloves, as the leaf edges can be sharp
Indoors: Lemongrass can grow indoors with 6 hours of bright light from a sunny window, or 12–16 hours of supplemental light provided by cool white fluorescent or LED lamps.
Pets: Dogs and cats may develop an upset stomach if ingested
