5 Tips How to Grow a Sweet Potatoes

Growing your own sweet potatoes is easier than you might think—and incredibly rewarding.

These colorful, nutrient-rich tubers love warm weather and can thrive even in small home gardens.

Whether you’re a beginner or an experienced gardener, these five essential tips will help you grow sweet potatoes successfully and enjoy a delicious harvest.

1. Choose Healthy Slips and the Right Variety

Sweet potatoes are grown from slips, not seeds. Slips are young sprouts taken from mature tubers.

When buying or making your own, look for sturdy, healthy slips with no signs of mold or rot.

Popular varieties include Beauregard (fast-growing and great flavor), Jewel (excellent storage life), and O’Henry (cream-colored flesh).

Choose one that fits your climate and growing season.

How to Make Your Own Slips

Place a sweet potato in water, half-submerged, and keep it in a warm, bright spot.

In about 3–4 weeks, it will sprout slips. Once they reach 5–6 inches long, twist them off gently and place them in water to root before planting.

2. Prepare Warm, Loose, and Well-Draining Soil

Sweet potatoes love loose, sandy soil that drains well. Compact or heavy clay soil can stunt their growth and deform the tubers.

Mix in compost or aged manure before planting to enrich the soil with organic matter. Aim for a slightly acidic to neutral pH (5.5–6.5).

If you live in a cooler region, consider using raised beds or black plastic mulch to warm the soil earlier in the season.

3. Give Them Full Sun and Warm Temperatures

Sweet potatoes need full sun—at least 6 to 8 hours a day—to develop properly. They grow best in temperatures between 75°F and 90°F (24°C–32°C).
Avoid planting too early; wait until all danger of frost has passed and the soil feels warm to the touch.

In colder climates, start slips indoors a few weeks before transplanting outside.

4. Water Consistently but Avoid Overwatering

During the first few weeks after planting, keep the soil consistently moist to help slips establish strong roots.

Once the vines begin to spread, water deeply once or twice per week, depending on rainfall.

Too much water can cause rot, while dry soil leads to small, misshapen tubers. Adding a layer of mulch helps retain moisture and suppress weeds.

5. Harvest and Cure for the Best Flavor

Your sweet potatoes are ready to harvest when the leaves start to yellow, usually 90–120 days after planting.

Use a garden fork to gently lift the tubers, taking care not to bruise them.

Curing Your Sweet Potatoes

Curing is key to sweet flavor and long storage.

Keep the harvested tubers in a warm (80–85°F / 27–29°C) and humid spot for about 10 days, then store them in a cool, dark, and dry place.

Properly cured sweet potatoes can last for several months.

Enjoy Your Homegrown Sweet Potatoes

With a bit of patience and warmth, growing sweet potatoes can be one of the most satisfying garden projects.

They’re versatile, nutritious, and beautiful additions to your garden beds or containers.

Once you harvest your first batch, you’ll see why gardeners everywhere love this resilient, sun-loving crop.
