Germination & Seedling
10-14 daysSeeds sprout and emerge as delicate seedlings with cotyledons visible. First true leaves appear within 7-10 days.
Ensure consistent soil moisture. Protect from birds and heavy rain. No fertilizer needed at this stage.
Vegetative Growth
3-4 weeksPlants develop multiple stems, leaflets, and tendrils. Bushy growth with characteristic compound leaves and climbing or bushy habit depending on variety support.
Provide sturdy trellises, stakes, or netting for climbing varieties. Water regularly and mulch to retain moisture. Side-dress with balanced fertilizer if growth appears slow.
Flowering
2-3 weeksPlants produce delicate white or pale pink flowers in leaf axils. Flowers are self-pollinating and typically set fruit readily.
Maintain consistent watering during flowering. Avoid high-nitrogen fertilizer to prevent excessive leaf growth at the expense of flowers. Ensure adequate support structures are in place.
Pod Development & Filling
3-4 weeksFlowers fade and pods rapidly enlarge, filling with developing peas. Pods turn bright green and become firm. Peas inside develop the characteristic large, round marrowfat appearance.
Continue regular, deep watering—critical for full, sweet peas. Monitor for pests. Harvest regularly to encourage continued pod production.
Maturity & Harvest
1-2 weeks peak harvest windowPods fully fill and firm up. Peas reach maximum sweetness at this stage. Pods may be harvested fresh or left to mature for drying.
Harvest pods when they feel full and heavy but still snap crisply. For dried marrowfat, allow pods to dry on the plant until papery. Cool harvested peas immediately if eating fresh.

Harvest Tips
Harvest pods when they feel plump and heavy but still snap crisply, typically 2-3 weeks after flowering begins. Pick in the morning when peas are cool and sweetest. Twist pods gently from the vine to avoid damaging stems. For fresh eating, chill immediately and use within a few days. For drying, allow pods to brown and papery on the plant (60+ days), then shell and store in cool, dry conditions.
