How to grow arugula in Mississippi, step by step
- Prepare the bed. It needs 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 8 inches deep, with a pH between 6.0 and 7.0. Dig in compost before planting.
- Sow outdoors (Feb 15 – Mar 6). Space plants about 4 inches apart in rows 10 inches apart, sowing seed ¼ 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 Mississippi.
- 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: flea beetle, aphids, cabbage worm. Diseases and disorders: downy mildew, white rust.
- Harvest (from about Mar 22 – Apr 1). Arugula takes 30-40 days to reach harvest. One of the fastest crops - baby leaves in about 3 weeks. Turns sharp and bitter and bolts in heat, so it is a spring/fall green. Flea beetles love it; grow under mesh.
