Dil seeds

Successful cultivation requires warm to hot summers with high sunshine levels; even partial shade will reduce the yield substantially. It also prefers rich, well-drained soil. The seeds are viable for three to ten years. The plants are somewhat monocarpic and quickly die after “bolting” (producing seeds). Hot temperatures may quicken bolting.

The seed is harvested by cutting the flower heads off the stalks when the seed is beginning to ripen. The seed heads are placed upside down in a paper bag and left in a warm, dry place for a week. The seeds then separate from the stems easily for storage in an airtight container.
