Germination & Seedling
2-3 weeksSeeds sprout within 7-10 days. Seedlings emerge with cotyledons followed by true leaves. Growth is initially slow.
Ensure consistent soil moisture. Provide support structure early if using trellising. Thin seedlings if sown densely.
Vegetative Growth
3-4 weeksVines develop with compound leaves and tendrils. Plants grow to 24-28 inches tall. Root system establishes deeply.
Install sturdy supports or trellises early. Water regularly. Apply mulch to retain moisture and regulate soil temperature. Monitor for weeds.
Flowering
2-3 weeksWhite or pale pink flowers appear in clusters along the vine. Flowering indicates upcoming pod set.
Maintain consistent watering; stress during flowering reduces pod set. Do not over-fertilize with nitrogen. Check for pests like aphids.
Pod Development & Filling
2-3 weeksPods form and elongate, gradually filling with developing peas. Pods transition from light green to medium green.
Water deeply and consistently. Provide shade cloth if temperatures exceed 75°F to prevent heat stress. Feed with balanced fertilizer if needed.
Harvest-Ready
1-2 weeks of continuous harvestPods reach 2.5-3 inches long and feel plump and firm with visible pea shapes inside. Peas are sweet and tender.
Harvest regularly to encourage continued pod production. Handle vines gently to avoid damaging future flowers. Morning harvest yields sweetest peas.
