Seedling
2-3 weeksTwo cotyledons emerge, followed by small true leaves. Plants are 2-3 inches tall.
Ensure consistent moisture and good drainage. Thin crowded seedlings to proper spacing. Keep soil temperature cool (50-65°F ideal).
Vegetative Growth
3-4 weeksBushy plants develop with multiple stems, compound leaves, and tendrils. Height reaches 18-24 inches.
Provide light support or trellis if desired, though Cascadia is more compact than tall varieties. Water consistently. Monitor for spider mites in dry conditions.
Flowering
2-3 weeksSmall white or pale pink flowers appear in leaf axils. Flowers are delicate and short-lived.
Maintain even watering to prevent flower drop. Continue light fertilizing if soil is poor. Avoid high-nitrogen fertilizers that promote foliage over flowers.
Pod Development & Early Harvest
3-4 weeksPods form and fill with peas. Early pods are tender and flat; mature pods are plump and sweeter. Plants produce continuously.
Pick pods regularly to encourage continued production. Harvest snap peas when pods are firm but tender, not fully mature. Pick in early morning for crispness.
Peak Production & Decline
2-3 weeksMaximum pod yield; plants may show signs of stress in heat. Production slows as temperatures rise above 75°F.
Continue harvesting to stimulate more flowering. Provide afternoon shade in hot climates. Plant decline is normal as season ends; remove plants after frost.

Pollinator support
WildlifePea flowers attract bees and other beneficial pollinators, supporting garden biodiversity and ensuring good pod set. [source]
Harvest Tips
Pick pods when 3-4 inches long and pods are full but still tender and bright green—harvest 2-3 times per week at peak production. Snap peas are sweetest and crispest when picked in cool early morning. Regular harvesting encourages more flowering. Plants decline in heat; pull up after frost kills them.
