How to plant sweet potatoes
Sweet potatoes are one of the easiest to grow vegetables, provided you have the right climate.
Florida is perfect for sweet potatoes. They like the heat, they like the long summers and they don't need much care.

Step 1: Get Your Planting Material!
This isn't hard. Sometimes your local feed store or nursery will sell "slips," which are just rooted segments of vines. This is a really easy way to get started, but if you have a little more time you can make your own sweet potato slips like I teach you here.
You can also simply buy a bag of sweet potatoes and start burying them in the garden... or take chunks of vine off an existing plant and start plunking the stems a few inches deep into the ground.

Generally, we eat most of the big sweet potatoes through the winter and keep a basket of the smaller ones for planting in the spring. It doesn't matter that they're small. Unlike individual fruit or vegetables, the sweet potatoes we harvest all contain the exact same genes as the big ones we ate so there's not a problem with "selecting" for tiny roots. They're clones!
Step 2: Prep Your Bed
You don't have to worry too much about preparation for sweet potatoes. Loose, loamy soil is great... but they'll also grow in so-so sand without many complaints.

This is pretty lousy area that generally fails to yield well, so we're going with our drop-dead easy survival staple this time around. We'll see how they do. I covered the area in fall with a mixture of rye and lentils as a green manure cover crop.
Here's what it looked like before I busted out the tiller:

Step 3: Water Well... and Stand Back!
Sweet potatoes will take off in warm weather and need little to no irrigation in years with decent rainfall. They also tend to run over most weeds and control the area where you plant them... and the areas around the garden... and the areas beyond that. I have them coming up 20' from where I planted them last year. My kind of plant.

As a final note - sweet potatoes make a great ground cover for food forests, especially in the more tropical areas of Florida where they'll grow year round. As a bonus, the longer you leave them in the ground... the bigger the roots tend to get.
Sweet potatoes are easy to grow and easy to plant. Get to it!
