Before Planting

Give Lemongrass a full-sun to lightly shaded site with fertile, well-drained soil that retains moderate moisture. Work compost into the bed and prepare a fine, weed-free surface for the usually small seed. Plan convenient irrigation, and use containers or barriers before planting if lemongrass may spread aggressively.

Planting

Sow lemongrass indoors several weeks before the last frost or direct sow when the crop’s preferred soil temperature is reached. Maintain even surface moisture through germination, especially for fine or slow seed. Give indoor seedlings strong light, harden them before transplanting, and thin direct-sown plants after true leaves appear. Repeat sowings where young leaves are harvested continuously.

Watering

Maintain steady root-zone moisture around lemongrass, especially during active leaf growth. Water before plants wilt, but avoid standing water and overhead irrigation late in the day.

Fertilizer

Apply light, regular nutrition to lemongrass during vigorous growth, especially in containers. Keep nitrogen moderate and stop feeding when plants become dormant or growth slows.

Harvesting

Lemongrass may be cut repeatedly once vigorous growth begins. Use clean shears, harvest before flowers fully open for best leaf quality, and collect seed heads only after they turn dry.

Tips

Keep lemongrass compact by harvesting or pinching often. Container plants may need occasional repotting, while tender perennials can be moved indoors before frost for continued growth.

Pests & Diseases

Rust, leaf blight, and root rot are the principal lemongrass diseases. Rust produces orange-brown pustules that can spread through dense clumps. Remove infected leaves before overwintering plants indoors, divide only clean sections, and avoid letting container roots stand in water during cool, low-light months.

Lemongrass may attract aphids, spider mites, caterpillars, slugs, or beetles. Inspect before harvest, use physical removal first, and avoid persistent broad-spectrum products on foliage intended for use.
