Growth Stages

1

Germination & Seedling

1-2 weeks

Seeds sprout in 7-10 days. Seedlings emerge with two cotyledons and develop their first true leaves.

Keep soil consistently moist but not waterlogged. Ensure good air circulation. No fertilizer needed yet.

2

Vegetative Growth

2-3 weeks

Plant develops compound leaves and climbing tendrils. Stems grow 12-18 inches tall.

Provide sturdy trellis or support structure early. Water regularly. Light feeding with balanced fertilizer if soil is poor.

3

Flowering

1-2 weeks

Delicate white flowers appear in clusters along the vine. Flowers are self-pollinating but benefit from bee activity.

Maintain consistent watering. Avoid high-nitrogen fertilizer which promotes foliage over flowers. Flowers indicate pod set is beginning.

4

Pod Development & Maturation

3-4 weeks

Flat, tender pods develop behind fading flowers. Pods reach 3-4 inches long and turn from green to full maturity.

Water consistently to prevent pod toughness. Monitor for pests. Pick pods regularly to encourage continued production.

5

Harvest Ready

2-3 weeks active harvest

Pods are full-sized, flat, and tender with sweet flavor. Peas inside are small and immature (this is characteristic of snow peas).

Pick pods every 2-3 days for tender texture. Morning harvest is best. Handle vines gently to avoid breaking them.

Fun Facts

  • 🌱 Snow peas are eaten with the entire pod, unlike snap peas and shell peas, making them unique among pea varieties.
  • 🌱 The white flowers of Cascadia White are not only beautiful but also indicate high sugar content in the developing pods compared to other pea varieties.
  • 🌱 Peas are nitrogen-fixing legumes that actually improve soil fertility by converting atmospheric nitrogen into usable form, reducing the need for synthetic fertilizers.
