How to grow potatoes in Texas, 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 4.8 and 6.5. Dig in compost before planting.
- Sow outdoors (Feb 24 – Mar 15). Space plants about 12 inches apart in rows 32 inches apart, sowing seed 4 inches deep. It tolerates a light frost but not a hard freeze. As a cool-season crop it does best before summer heat arrives in Texas.
- 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: Colorado potato beetle, flea beetle, wireworm, aphids. Diseases and disorders: late blight, early blight, common scab, blackleg.
- Harvest (from about May 10 – Jun 29). Potato takes 70-120 days to reach harvest. Plant certified seed potatoes, not grocery-store ones. Hill soil or mulch over the stems as they grow to stop greening. New potatoes ~10 weeks in; storage potatoes after the tops die back.
