Growing Method Step 1: Select a sunny location with loose, well-drained soil. Remove weeds and break up large soil clods. Step 2: Sow seeds thinly on the soil surface, cover lightly with 0.3cm fine soil and mist water gently. Step 3: Keep soil evenly moist, avoid waterlogged soil that leads to seed rot. Step 4: When seedlings develop 2 to 3 true leaves, thin the seedlings, leaving 20–25cm spacing between each plant. Step 5: Water moderately during dry weather. This plant tolerates mild nutrient-poor soil, excessive fertilizer is not required. Step 6: Remove ripe berries before they drop if you want to limit self-sowing and spreading. Step 7: Collect seeds from fully black ripe berries at the end of growing season for next-year planting.
