what zone for lemon grass
WHEN TO GROW. Lemongrass is a perennial in growing zones 10 and warmer but can be grown as an annual in cooler climates, though it may be difficult to grow outside in zones 8 and colder. In general, youâll plant lemongrass after the danger of frost has passed, in late spring for a late summer harvest. Lemongrass takes at least 100 days and sometimes up to 4-8 months to be ready for harvest. WHERE TO GROW. Lemongrass prefers warm, moist and humid conditions. Grow lemongrass outdoors only in hardiness zones 9 and warmer. Grow lemongrass indoors year round in a very sunny window. If growing in containers, youâll likely want at least 5 gallons of space to have a worthwhile lemongrass plant.
