Soil Type

Water: Lemon grass thrives in tropical climates, favoring high humidity and frequent rain. It requires consistent moisture, ideally watered twice a week. Regular watering during the growing season promotes lush foliage and aromatic qualities, mimicking its natural environment effectively.

Fertilize: For lemon grass, use organic mulch or compost for slow-release nutrients and fertilize bi-monthly in growing seasons, reducing in winter. Apply a thin layer, avoiding stem contact. Water post-application and use gloves for safety to enhance vigor and resilience while adjusting for seasonal growth variations.

Pruning: Lemon grass is a perennial grass that thrives with early spring pruning, removing about a third of its foliage. This practice improves air circulation, minimizes pests, and stimulates new growth. Care should be taken to avoid over-pruning to maintain the plant’s strength and vigor.

Propagation: Lemon grass propagates best through division in Spring and Autumn. Successful propagation is indicated by new shoot growth. Ensure divisions possess sufficient root structures to enhance success rates.

Repotting: For lemon grass, repot every 2-3 years during early spring to support rapid growth. Use a large container to accommodate dense roots. After repotting, place in a sunny location and maintain regular watering, ensuring good drainage to avoid root rot.
