How to Grow Cascadia
Pisum sativum
Cascadia is a reliable heirloom garden pea offering tender pods in just sixty days. Gardeners prize this easy-to-grow variety for its ability to thrive in cool weather while providing a nutritious harvest from early spring through late summer.
📷 Wikipedia: PeaStarting Cascadia: indoors or direct sow?
🌾 Sow directly in the garden — Cascadia is not usually started indoors.
Direct sow seeds outdoors two to six weeks before the last frost date; do not transplant seedlings as peas develop best from direct seeding.
Soil, care & harvest
Prepare loose, well-drained soil with a pH between 6.0 and 7.0. As a cool-season crop, sow seeds directly outdoors two to six weeks before your last expected frost date. Bury the seed about one inch deep in the soil. Expect germination within seven to fourteen days once conditions are right.
Space plants two to three inches apart to encourage healthy growth. Because Cascadia grows relatively short at twelve to eighteen inches, sturdy trellising or netting is not strictly necessary but can support climbing varieties if selected. Provide one inch of water weekly, keeping soil consistently moist for best pod quality. Apply a light layer of mulch to retain moisture and suppress weeds.
Watch for aphids, thrips, pea weevils, and leaf miners; encourage beneficial insects or use insecticidal soap if infestations appear. Prevent root rot by ensuring good drainage, while monitoring for powdery mildew and bacterial blight. Harvest pods sixty days after sowing when they are plump but still crisp to the touch.
