How to plant

Sweet potatoes are grown from rooted stem cuttings called slips, not seed. Suspend a supermarket tuber half-submerged in water on a warm sill; when 6-in sprouts appear, twist them off and root in water for 1 week. Plant slips into loose ridged soil after nights are warm. Dig gently before frost.

Grower's tip

Cure dug roots at 80–85°F and 85% humidity for 10 days — that converts starch to sugar and heals nicks. Then store at 55–60°F for months.

Soil preferences

Soil type

Deep, loose, stone-free sandy loam — rocks and clumps fork roots.

pH range

6.0–7.0

Amendments

Avoid fresh manure or heavy nitrogen (causes hairy or forked roots). A light compost and rock phosphate work well.

Watering

Frequency

Steady moisture — 1 in per week. Uneven watering causes cracking.

Method

Deep soaking; avoid shallow daily watering that keeps roots near the surface.

Over vs. under

Overwatered: cracked or rotted roots, foliage disease. Underwatered: woody, hot-flavored, or bitter roots.

Top-water or bottom-water?

Prefers top-watering — Top-water at the base. Wet foliage spreads late blight and early blight; keep leaves as dry as possible.

Temperature tolerance

Ideal daytime air temp

60–75°F (15–24°C)

Ideal nighttime air temp

45–65°F (7–18°C)

Frost sensitivity

Carrots, parsnips, beets sweeten after frost. Storage roots can often overwinter in the ground under heavy mulch.

Container growing

Container-suitable?

Possible with the right cultivar

Recommended pot size

12+ in deep for full-size carrots and parsnips; 8 in deep is fine for radish and short carrots

Notes

Pick short or round cultivars (Parisian carrots, Chioggia beets) for shallow containers.

Succession planting

Radish every 2 weeks. Carrots and beets every 3–4 weeks spring through late summer.

Detailed harvesting

Loosen soil with a fork before pulling to prevent snapped tops. Twist off greens 1 in above the crown for storage; leave 1 in of stem on beets to prevent bleeding.

Post-harvest storage & preservation

Trim tops; store unwashed in damp sand or perforated bags in the fridge or root cellar at 32–40°F. Most root crops keep 3–6 months.

Culinary, medicinal & other uses

Fresh, roasted, fermented (kraut, kimchi), pickled. Tops of beets, radishes, and turnips are edible greens.

Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.

Seed saving

Pollination

Biennial and insect-pollinated. Root crops cross widely (carrots cross with Queen Anne's Lace).

Isolation needs

1/2 mile in the open or use cage with introduced pollinators.

How to save

Overwinter the best roots; replant in spring; collect the dry umbels/seed stalks in year 2.

From your kitchen — grow sweet potato from what you already have

Grown from 'slips' — leafy shoots you sprout off a stored root. One grocery sweet potato gives 10–20 slips.

  1. 1Suspend a whole sweet potato half-in / half-out of a jar of water using toothpicks. Keep in a warm bright spot.
  2. 2In 4–6 weeks leafy sprouts appear on the top half. When shoots are 6 in tall with 3–4 leaves, twist them off at the base.
  3. 3Set the twisted-off slips in a glass of water 5–7 days until they grow roots.
  4. 4Plant rooted slips 4 in deep, 12 in apart, once soil is warm (65°F+).

Storage: Save one or two roots from harvest to sprout again next spring.
