Germination
7-14 daysSeeds sprout and tiny seedlings emerge with two cotyledons. Root system begins developing.
Keep soil warm (70-80°F) and consistently moist. Thin seedlings to proper spacing once they have true leaves.
Vegetative Growth
4-6 weeksPlant develops true leaves and stems thicken. Height increases rapidly to 1-2 feet. Foliage is abundant and green.
Water regularly, provide full sun, and apply balanced fertilizer every 3-4 weeks. Remove weeds to reduce competition.
Flowering
4-8 weeksTubular flowers appear in leaf axils, typically white, pink, purple, or red. Flowering progresses from bottom to top.
Maintain consistent watering and full sun. Avoid excess nitrogen, which promotes foliage over flowers. Hand-pollinate if bee activity is low.
Pod Development & Maturation
3-6 weeksFlowers fade and elongated seed pods form along the stem. Pods gradually fill with seeds and change color from green to brown or tan.
Reduce watering frequency as pods mature. Watch for pest activity and monitor for disease. Do not overwater to avoid pod rot.
Harvest Ready
1-2 weeks before harvestPods dry and turn brown or golden. Lower pod leaves may yellow and drop. Stems become woody. Seeds inside pods are firm and mature.
Stop watering 1-2 weeks before harvest. Plant can be cut and hung to dry. Harvest when lower pods shatter easily when pressed.
Common Pests
-
Hand-pick affected leaves; use neem oil spray; encourage natural predators like parasitic wasps; rotate crops annually.
-
Increase humidity by regular misting; spray neem oil or insecticidal soap; remove heavily infested leaves.
-
Remove and destroy affected stems; use pheromone traps; apply insecticidal dust in early morning; practice crop rotation.
-

Harvest Tips
Harvest when lower pods turn brown and dry, and seeds rattle inside when shaken—typically 90-150 days after planting. Cut the entire plant at soil level and hang upside down in a warm, dry location for 2-3 weeks. Once fully dry, thresh pods by hand or gently beating them to release seeds. Winnow to remove chaff and debris. Store seeds in airtight containers in a cool, dry place.
