• Leave 30–40 cm between rows for easy care.
• Water immediately after sowing to maintain moisture.

D. Germination — 7–14 days after sowing

• Seeds require 15–22°C for successful germination.
• Keep the soil moist without flooding it.
• After seedlings emerge, gradually reduce watering to prevent root rot.

E. Plant care — months 1–5
