Miscellaneous 

Soil

Any well drained soil.

Position

Full sun.

Frost tolerant

Lemongrass is a tropical plant that freezes to death where winter temperatures drop below -9C (15F). In all areas, potted plants are easy to keep through winter indoors.

Feeding

None generally needed.

Companions

Coriander, Echinacea and Basil.

Spacing

Single Plants: 70cm (2' 3") each way (minimum)
Rows: 60cm (1' 11") with 90cm (2' 11") row gap (minimum)

Sow and Plant

Start with a purchased plant in spring, and grow it in a pot until the soil warms in early summer. You can also root a stalk from the produce market in water. Plant lemongrass in a warm, sunny spot that is convenient to water.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

In late summer, dig away an outer stalk, cut back the leaves to 3 inches (8 cm), and plant it in a small container. Grow it through winter in a sunny windowsill, providing only small amounts of water, and replant outdoors the following spring.

Harvesting

Leave the plant to develop some thick stems before starting to harvest. The most tender leaves are found close to the stems.

Troubleshooting

Plants may rot in poorly drained clay soil. When lemongrass is grown in containers, shift the plants to larger pots as needed. When the roots become crowded, they can cause clay pots to crack.
