Soil and climate
Well drained Sandy loamy/black soil pH of 6.5 to 7.5 is preferred. It grows well as tropical and sub tropical rainfed crop.

Sowing:Plough the land twice/thrice and level the top soil. About 1 kg of seeds is required for raising seedlings to plant in one ha. The seeds germinate in about a week and are maintained upto 20 days. Soaking the seeds in fresh water for 20-30 minutes before sowing would help in increased germination. Also seed treatment with GA3 200 ppm for 6 hours increased germination percentage.

Spacing and Transplantation
3 to 4 week old plantlets can be transplantedat a spacing of  10x15 cm, accommodating 8 lakhs seedlings/ha

Manuring
To encourage good vegetative growth, apply 10-20 tonnes of FYM, 50 kg N, 25 kg each of P2O5 and K2O are applied per hectare. Half the dose of N, entire dose of P and K is applied as basal and the remaining N is applied in two split doses, the first at 30th day and the second at 60th day.

Plant protection
Normally in this herb the pest and disease management efforts required are not high.

Harvest
If cultivated in June to July, the plant is ready for cultivation in September to October.
September harvesting is ideal for high Phyllanthin. From the date of the planting, in 80 to 100 days the plants grow to the maximum.  

Yield    
An average yield of 17.5 tonnes of fresh herbage or 1750 kg/ha of  dry herb is obtained.
