How to grow peas in Maryland, step by step
- Prepare the bed. They need at least six to eight hours of direct sun a day and loose soil at least 18 inches deep, with a pH between 6.0 and 7.5. Dig in compost before planting.
- Sow outdoors (Mar 5 – Mar 24). Space plants about 2 inches apart in rows 18 inches apart, sowing seed 1 inch deep. It handles frost well, so it can go out before the last frost date. As a cool-season crop it does best before summer heat arrives in Maryland.
- Water and feed. Give it steady, even moisture, about an inch of water a week from rain or the hose.
- Watch for pests and problems. Pests: aphids, pea weevil, armyworm. Diseases and disorders: powdery mildew, fusarium wilt, root rot.
- Harvest (from about May 4 – May 19). Pea takes 55-70 days to reach harvest. Sow as soon as the soil can be worked - 4 to 6 weeks before the last frost. Production stops once daytime highs stay above ~80 F.
