Germination
7-14 daysSeeds sprout and initial leaflets emerge from soil
Soil temperature should be at least 60°F, ideally 70°F+. Keep soil consistently moist but not waterlogged. Germination occurs in 7-14 days.
Vegetative Growth
3-4 weeksPlant develops compound leaves and establishes bushy growth habit, typically 12-18 inches tall
Thin seedlings to proper spacing. Water moderately. Apply mulch to retain soil moisture and regulate temperature. No fertilizer needed due to nitrogen fixation.
Flowering
2-3 weeksSmall purple or pink flowers appear along stem nodes
Maintain consistent moisture during flowering to support pod set. Avoid excessive nitrogen which promotes foliage over flowers. Light feeding with balanced fertilizer if soil is very poor.
Pod Development
3-4 weeksPurple-hulled pods develop and elongate, reaching 6-8 inches long
Continue regular watering to support pod fill. Monitor for pests. Pods mature from green to purple as they age.
Harvest Maturity
Ongoing from 70-90 days onwardHulls turn dark purple to black, seeds inside mature and rattle when shaken
Begin harvesting when pods are full but still tender for fresh consumption, or wait until fully mature for shelling dried peas. Pick regularly to encourage continued production.

Harvest Tips
For fresh snaps, harvest when pods are full but still tender and bright purple, about 3-4 days after flowering. For shelling fresh, wait until pods are fully developed but still green/purple. For dried peas, allow pods to mature completely on the plant until hulls turn dark purple-black, seeds rattle, and pods begin to dry. Pick pods regularly to encourage continuous flowering and production. Cut pods from the plant rather than pulling to avoid damaging the plant.
