Climate

The ideal temperature to grow lemon grass is 10-33C, sowing temperature of 20-27 degree.  The average rainfall is 250-280cm and harvesting temperature is 30-34 degree.

Soil

The grass is hardy and grows in variety of soil composition. It grows easily in loamy soil, alluvial soil and sandy soil. Avoid growing on waterlogged soil or soil with poor drainage.

Production

The production is through rain-fed grass or irrigation. Ideal soil condition is marginal soil and alkaline soils. The soil PH level is from 9.6, grow in medium fertile soil and requires moderate irrigation.

The grass grow in tropical and sub-tropical regions, well-drained sandy loam soil conditions. Ideal weather condition is warm humid 300cm rainfall per year and adequate sun. Waterlogged soil would kill the grass and the crop is susceptible to certain pest and diseases.

Propagation

Lemon grass can be vegetable propagated or raised via seeds. Propagation through seeding is encouraged and a plant can produce 150 g seeds. They flower November and seeds mature in 2 months.

Nursery operators cut the inflorescence and dry in sun for 3 days then thresh. Seeds dried still attached to mass and removed by beating the seed bag.

The dry seeds are durable in storage and last eight months. Vegetable propagation is by splitting the clumps then spaced 60 x 70cm.

Nursery Planting

The seeds are a sown by hand in beds 1m x 1.5m width. 2.5 kg seeds can produce enough seedlings for 1ha land or at a rate of 4kg/ha.

The seeds are sown and covered with top soil then watered immediately. It is important to maintain soil moisture in nursery. The seeds germinate in 6 days and are ready for transplanting in 2 months.

Transplanting

Plant on ridges in area with high rainfall and adequate sun. Space the seedlings 40 x 40 cm apart and water immediately or establish an irrigation schedule.

Introduce nitrogen, zinc sulphate to soil with low fertility. Hand hoe, weed to remove competing plants and apply herbicide as specified.

Pests and Diseases

Lemon grass are susceptible to different pests and diseases.  Common pests are nematodes and stem boring caterpillar. Diseases include leaf blight, grassy shoot and leaf blight.

  • Nematodes
  • Stem boring caterpillar
  • Leaf blight
  • Grassy shoot
  • Leaf blight

Harvesting and Post-Harvest

Harvesting is done 6 months from planting the seedlings. The post-harvest management involves drying, distilling and oil purification. Other post activities are storage and packaging of oil.
