Germination & Emergence
7-10 daysSeeds sprout and seedlings emerge with cotyledons visible. Young shoots grow upward.
Keep soil consistently moist but not waterlogged. Provide support structures early so vines can climb. Protect from birds and slugs.
Vegetative Growth
3-4 weeksTall vines develop with compound leaves and tendrils. Plant reaches 4-6 feet in height, becoming bushy with multiple stems.
Ensure sturdy trellises or stakes are in place. Monitor for aphids and mites. Provide consistent watering. Thin if overcrowded.
Flowering
2-3 weeksWhite, pink, or purple flowers appear along the vine at leaf axils. Flowers are delicate and abundant.
Do not apply nitrogen fertilizer as it promotes foliage over flowers. Maintain steady watering to support flower and pod set. Pollinated by bees and other insects.
Pod Development & Maturation
3-4 weeksPods swell and elongate behind spent flowers. Pods progress from light green to darker green as seeds mature inside.
Increase watering during this critical stage to ensure tender, full pods. Harvest regularly to encourage continued production. Look for pods that feel full but are still bright green.
Harvest-Ready
Variable (ongoing until frost or vine decline)Pods are plump, firm, and glossy; seeds inside are fully sized. Harvest window is relatively narrow before peas become starchy.
Harvest every 2-3 days to prevent pods from becoming tough and overripe. Grasp vine gently with one hand while picking with the other to avoid plant damage.

Uses
Fresh Snap & Snow Peas
CulinaryAlvesta peas can be eaten fresh in pods as crisp snap peas when harvested young, or the tender pods can be blanched and frozen. The sweet flavor makes them ideal for fresh salads, stir-fries, and side dishes. [source]
Shelled Garden Peas
CulinaryWhen allowed to mature fully, the sweet seeds can be shelled and eaten fresh, frozen, or dried for winter storage. Alvesta's heirloom sweetness is ideal for pea soup, purees, and traditional dishes. [source]
Nitrogen Fixation & Soil Improvement
HouseholdLike all legumes, Alvesta peas form symbiotic relationships with nitrogen-fixing bacteria, naturally enriching the soil. After harvest, leave roots in place or incorporate vines into compost to improve soil fertility for next year's crops. [source]
Nutritional Value
MedicinalFresh peas are rich in vitamins C, K, and B vitamins, as well as fiber and plant-based protein. They contain polyphenol antioxidants that support overall health and immune function. [source]
Pollinator & Beneficial Insect Support
WildlifeAlvesta's abundant flowers attract honeybees, native bees, and other pollinators while supporting beneficial insects in the garden. The tall vines also provide shelter for ground beetles and other predatory insects. [source]

Harvest Tips
Begin harvesting 60-75 days after planting when pods are full but still bright green and tender. Alvesta can be harvested as snap peas (pods and all) when young, or as shelling peas when mature. Harvest every 2-3 days to encourage continued blooming and pod production. Pick early in the morning when peas are crisp. Hold the vine gently with one hand while picking with the other to avoid damaging the plant. Pods become tough and peas become starchy if left too long on the vine.
