Growing sweet potatoes successfully starts with preparing and planting the bed. Do that right, and you’ll reap an abundant harvest!

Growing Sweet Potatoes: Preparing and Planting a Bed

Growing sweet potatoes is easy.

Preparing a bed for sweet potatoes is a little more difficult. It takes some digging and loosening of the soil.

Fortunately, my trusty Meadow Creature Broadfork is always up to the task of growing sweet potatoes.

Digging in sandy soil with a broadfork is easy. In rocky clay, it’s not nearly as easy to prepare a bed for growing sweet potatoes. Basically, in clay, it’s an extreme sport.


It’s not impossible, though. That bed took me perhaps 45 minutes to prepare. Mostly, it takes more stomping on the broadfork than I’m used to, plus I had to bust up the big clods.

Sure, it’s work—but it’s work that needs to be done, especially for root crops.

Why Dig a Garden Bed?

The major reason: loose soil. If the soil structure is open and crumbly, plant roots do a lot better. They can dig deep and get the minerals and water they need without having to force their way through hard earth. You’re doing the hard work first to make their lives easier.

Digging garden beds even works well in sand, as I discovered back in Florida.

When your plants have easier lives, they’ll spend more time making delicious things for you to eat.

Growing Sweet Potatoes: The Initial Feeding

When I prepare a garden bed, I rake in compost right at the beginning. In the past, I’ve also used amendments such as lime, blood meal, bone meal, cottonseed meal, and kelp meal—all of which are excellent additions to the soil.

Here in the middle of nowhere, I can’t get most of those things, so I stick to compost, biochar, and sometimes seaweed.

You don’t need a ton of organic matter in the soil. A few percent is fine. Before I plant, I sprinkle about a half-inch cover of compost on a newly dug garden bed and rake or turn it in. The plants really appreciate compost, and it lasts longer and releases its nutrition over time, unlike chemical fertilizer.

When preparing this garden bed, I used my Back to Eden chicken run compost, which is probably hotter than compost from a typical backyard pile. The plants don’t seem to mind, though.

Here’s how I made that compost: (Length: 8:05 minutes)

Simple. Right?

Planting a Bed of Sweet Potatoes

This is easy as shoo-fly pie.

Just cut some vines and stick them in.

If you don’t have any vines currently growing on your homestead, start your own sweet potato slips with store-bought sweet potatoes.

Use the “toothpicks-and-a-jar” method—or even easier—start potatoes growing by burying them shallowly in a pot of soil. Then cut the vines off of those to plant.

I use a stick to dig holes. Then plant the sweet potato cuttings a few inches deep into the holes.

They’ll look like they’re going to die for a few days. Don’t worry! They’ll recover as the vines take root. Sweet potatoes are really hardy and tough.

You’ll be amazed by how good these little pieces of vine look after a week or two.

Planting a bed of sweet potatoes takes some prep work. If you do that preparation well, you’ll be rewarded with an abundant harvest.

      Just a few thoughts….. Find out what gardening zone you are in. (do an online check.. just type in your zip code)
      See what can grow there.

      Get a general idea of what your “soil PH” is… acid or alkaline.

      Better still, go to “Dave’s Garden” online . There’s a treasure trove of free info there… much more than I can help you with.

      Start out slowly, and don’t let information overwhelm you.

      Best of luck!

    Yeah, my neighbor gave me some cuttings from his vine and said just stick them in the ground. I watered 2x per day, but still only one out of five survived. So I tried again, putting them in a jar of water till roots developed. That worked much better. I’m in Houston, TX where it’s beastly hot so that could be a factor.

    Will this same method work for yams as well?
