How To Grow Sweet Potatoes

Traditional potatoes are sold and planted as “seed” potatoes. To plant, you can simply chop them up with an eye or two, and place in the ground.

Traditional potatoes are planted using chunks of potatoes cut up.

A traditional potato grow stems and leaves from the eyes. As a result, new potato plant emerges above ground.

And of course, new potatoes form underground.

But to grow sweet potatoes, it is a completely different process.

Instead of growing from portions of potatoes planted in the ground – sweet potatoes grow from slips.

So what are slips? Slips are nothing more that a sweet potato root with a few leaves.

Sweet potato slips can be made by submerging a sweet potato in water.

They can be purchased, or you can easily make your own from partially submerging a sweet potato in water. And after a few day – it will begin to grow it’s own slips.

One final note before getting on to planting instructions.

Sweet potato vines (edible) are not the same as the ornamental sweet potato vines that are grown in pots, baskets and containers.

While ornamental sweet potato vines will sometimes grow tubers or small potatoes – they are not in the least bit tasty!

How To Plant And Grow Sweet Potatoes

The best time to plant sweet potatoes is in late spring to early summer.

When planting, sweet potato slips should be planted up to their top set of leaves.

Although traditional potatoes are planted in early spring, sweet potatoes need a bit warmer soil. They are highly frost sensitive.

Sweet potatoes grow best in loose fertile soil. Adding a bit of compost to each planting hole goes a long way towards success. See : How To Make Great Compost

Plant slips 6 inches deep in the soil, spacing them 12 inches apart. It is best to mound the soil a bit before planting. Sweet Potato Slips – Product Link

Bury each slip in the soil all the way to the top set of leaves. Once planted, tamp the soil down around the top of each plant.

How To Grow Sweet Potatoes – Maintaining Plants In The Summer

Sweet potatoes need water to grow to proper size. Be sure to water plants at least twice a week if there is little rain.

Once sweet potato vines begin to grow, they will suppress most weeds.

It is a good idea to mulch plants early on. A bit of straw around each plant helps to conserve water and keep weeds at bay.

Once the plants begin to grow – their massive leaf structure will suppress the majority of weeds.

How To Grow Sweet Potatoes – Harvest Time

Sweet potatoes can begin to be harvested as soon as the plants begin to yellow.

However, the longer they stay in the ground, they continue to develop additional flavor.

You can partially harvest as well up until the threat of frost. This is a great method to take only what you will be using until you are ready for a full harvest.

Sweet potatoes dug up and ready for the curing process.

Sweet potatoes can store for a long time if kept in a cool, dark place. But they do need to be cured first.

Curing is a simple process of letting the potatoes dry out completely before moving to long-term storage.

In addition to preparing them for long-term storage, curing also aids in sweetening the potatoes up.

To cure sweet potatoes, begin by gently brushing all of the soil off of the skins. Do this without water – they will store much better keeping without cleaning completely.

Curing prepares the sweet potatoes for long term storage.

Once brushed off, place in a well-ventilated but warm spot for about 10 to 15 days.

A back porch, barn, or garage are all great places to cure. After the curing period, the sweet potatoes are then ready to take to a cool, dark spot to keep long-term.

Be sure to save back a sweet potato or two to grow your own slips the next year!

Sweet potato slips can be purchased from online garden sources, local garden centers or hardware stores. While tempting, it is not always a good idea to rely on sprouts grown from store-bought sweet potatoes. Many of the sweet potatoes have been treated to reduce sprouts, and you won't know the specific type of sweet potato you have purchased.

As an experienced gardener, you know that all containers are not created equal. Containers created specifically for potatoes, such as this Garden Vegetable Grow Bag, are easy to work with and are quite inexpensive compared to plastic or ceramic. These bags are designed specifically to provide aeration to the roots, adequate drainage and even side pockets to sneak a small spud here and there. When your sweet potatoes are ready to harvest, you simply lift the bag and dump the contents into a wheelbarrow making the harvest extremely easy. The Grow Bags are reusable and can be stored away for the next season. You can also use other containers such as whiskey barrels or clay containers just make sure they are wide and deep with adequate aeration and drainage.


A Few Quick Tips

I realize there may be a few other questions left to answer when curing and storing sweet potatoes. Let’s begin with how long sweet potatoes can last when cured.

First, if you cure your sweet potatoes, they can last up to one year. Everyone’s curing process can vary depending on how close they get to the actual recommended conditions.

So to be on the safe side, it is a good idea to meet the recommended conditions and allow the potatoes to stay in them for about a week. If your potatoes begin to darken, then you know that you need to turn up the heat because your potatoes are being stored in colder than desired temperatures.

Next, be sure that you have a proper location to store your sweet potatoes. This can be in a root cellar, in wooden boxes in a closet or basement, or you could do what I once did. I stored my produce in wooden boxes under my bed.

Either way, be sure to place them in the box in an orderly fashion with straw or sawdust to separate them to reduce the opportunity for rot to take place and ruin your harvest. You can also wrap them individually in a newspaper to keep them from directly touching and allowing rot to form.

Third, I mentioned this a little before, but be sure not to wash your sweet potatoes. Some people say that their potatoes are covered in hard clay so they give them a slight wipe down to remove some of the clay and haven’t faced any issues with rot.

However, unless your sweet potatoes are just really nasty, then I’d recommend avoiding washing them. This brings moisture to your products which obviously gives rot a head start.

Once you wash them, they are no longer shelf-stable and won’t last more than a week or two.

Finally, how will you know that your sweet potatoes have actually cured? In my own experience, the best way to judge is after between 7-10 days when you check them, they should be moist but more firm. If this is the case, then they are ready to be stored for another 6-8 weeks before eating.

So I think we have covered all you will need to know when curing a sweet potato. Hopefully, this will help you to enjoy your harvest all year long.
