How to grow garlic in Mississippi, step by step
- Prepare the bed. It needs at least six to eight hours of direct sun a day and loose soil at least 12 inches deep, with a pH between 5.5 and 7.5. Dig in compost before planting.
- 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: onion maggot, onion thrips, stem nematode. Diseases and disorders: white rot, rust, basal rot.
- Harvest. Garlic takes 240-270 days to reach harvest. Plant cloves 2-4 weeks after the first fall frost, pointy end up, and mulch. Hardneck types need this cold period; softneck types suit mild-winter regions and braid well. Harvest the following summer when the lower leaves brown.
