Growth Stages
Germination
7-14 daysSeeds sprout and first true leaves emerge
Ensure soil temperature is 60°F or higher; keep soil consistently moist but not waterlogged
Seedling & Climbing
2-3 weeksVines grow rapidly and begin twining around support structure; multiple leaves develop
Provide sturdy trellis or pole early; thin seedlings to proper spacing; water regularly
Flowering
2-3 weeksPurple flowers bloom along the vine; plant reaches full height and vigor
Maintain consistent watering; apply balanced fertilizer every 2-3 weeks; pollination occurs naturally
Pod Development & Production
3-4 weeksPurple pods form and elongate; plant produces continuously if harvested regularly
Pick pods every 2-3 days while young and tender (4-6 inches); regular harvesting encourages more production
Late Harvest & Senescence
2-4 weeks until frostPods continue to mature; plant growth slows as temperatures cool or frost approaches
Continue harvesting mature pods; allow final pods to dry on vine if saving seeds; frost will end season

Preservation through freezing or canning
CulinaryExcess harvest can be blanched and frozen for winter use, or canned using proper pressure-canning techniques. They retain good quality when preserved. [source]
