Sweet Potatoes: The Hard-to-Kill Southern Staple

If you want one crop that makes you feel like a pro, plant sweet potatoes. They love heat, they shrug off poor soil, and they ask for almost nothing. In the South, where summer breaks a lot of gardens, that is a perfect match. From zone 7b down to 11, sweet potatoes are one of the most forgiving, productive staples you can grow. Here is how to grow this hard to kill crop.

The Crop That Almost Grows Itself

Sweet potatoes are about as close to set it and forget it as gardening gets. Give them sun and room and they take care of the rest. That makes them a great confidence builder for new growers and a dependable staple for seasoned ones.

Start With Slips

You do not plant sweet potato seeds. You plant slips, which are rooted sprouts from a mature sweet potato. You can buy them or grow your own from a healthy sweet potato. Plant them after the soil warms up and the last frost is gone.

Give Them Room and Sun

Sweet potato vines spread out and cover the ground. Give them full sun and loose soil so the roots can swell.

• Loose soil grows bigger, smoother roots.
• Full sun feeds the vines that feed the roots.
• Space them out. The vines will fill in fast.

Then Mostly Leave Them Alone

This is the easy part. Once established, sweet potatoes handle heat and dry spells better than most crops. Water during long dry stretches, but do not fuss. Go heavy on water and fertilizer and you get lots of leaf and small roots. A little neglect actually helps.

Do Not Waste the Greens

The leaves are food too. Sweet potato greens are tender and cook up like other Southern greens. While you wait months for the roots, the vines feed you along the way. That is two crops from one planting.

Harvest in Fall

Sweet potatoes need a long season, usually a few months. Dig before your first frost. Lift them gently so you do not bruise them.

• Cure them in a warm spot for a week or two. This sweetens them and helps them store.
• Store cool and dry after curing and they keep for months.

One Patch, Months of Food

One small patch can feed your family for a long stretch of winter. Cured and stored right, sweet potatoes hold for months without a freezer or canner. That is a lot of food security for very little work.

Frequently Asked Questions

When do I plant sweet potatoes in the South?

After the last frost, once the soil is warm. In much of Florida that is late spring. They need a long, warm season to size up before fall.

Why are my sweet potato roots small?

Usually too much water and fertilizer, which pushes leafy vines instead of roots. Loose soil, full sun, and a little neglect grow bigger roots.

Do I really need to cure sweet potatoes?

Yes, if you want them sweet and storable. A week or two in a warm, humid spot after digging sets the skin, raises the sugar, and lets them keep for months.

Can you eat sweet potato leaves?

You can. The young leaves and tips cook up tender like spinach or other greens, so the vines feed you while the roots grow.
