Prefers full sun and well drained soil. Sandy to loam-sandy soils. Needs lots of organic matter. Keep moist. Fertilize soil 2-3 days before planting. Sow the seeds 0.5cm deep, making sure they are totally covered by soil (they require darkness to germinate). Thin out the seedlings to a distance of 15-30cm apart when they reach a height of 5cm. Keep the soil moist and feed fortnightly with 2:3:2.
