How to grow beets in Rhode Island, step by step
- Prepare the bed. They need six or more hours of sun for the best growth, though four to six hours in partial shade is enough and loose soil at least 12 inches deep, with a pH between 6.0 and 7.5. Dig in compost before planting.
- Sow outdoors (Mar 23 – Apr 11). Space plants about 4 inches apart in rows 12 inches apart, sowing seed 0.75 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 Rhode Island.
- 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: leaf miner, flea beetle, aphids. Diseases and disorders: cercospora leaf spot, scab, damping off.
- Harvest (from about May 17 – Jun 6). Beet takes 50-70 days to reach harvest. Each wrinkled 'seed' is a cluster of 2-4 seedlings - thin to one or transplant the extras while tiny. Thinnings are edible greens.
