Finally, My Sweet Potato Slips Are Here!

Finally I am planting my sweet potato slips, which just arrived mid-June. It’s very hot to be gardening, but I had no choice.

Way back in April I planted the sweet potato slips that I had started myself. And before that – back in January – I had pre-ordered a variety of sweet potato slips from Southern Exposure Seed Exchange.

I had expected them by mid-May. When June arrived and I hadn’t heard anything, I e-mailed SESE (Southern Exposure Seed Exchange). After a few days, I got a reply saying there was a problem with the postal service or something. I got my slips the next day.

Now it is June 15th and finally the sweet potato slips are here. They are basically a bunch of green stems. Pretty much all the leaves are brown and have fallen off. I know that sweet potatoes are hardy, so I am confident they will come back once they are planted.

I wrapped the stems in wet paper towels and left them on the counter overnight. All three of my raised beds are ready for planting, so I’ll be gardening in the morning.

Sweet potatoes like heat – I get that – but it’s been hot here for months. I could have easily planted my sweet potatoes two months ago. And it wouldn’t have been as hot for me to do the work!

I get that most places aren’t dealing with this climate, but an earlier shipping date would have been nice.

Once I get this variety to grow, I will save potatoes and make my own slips for planting next year and I can plant early. I ordered them to have a variety. It is an experiment to see which ones grow and taste best.

The Sweet Potato Slips

I discovered my box of sweet potato slips on the front porch on June 15th. It has been very hot and humid here for weeks. I opened the box and unwrapped my slips. It was very hot and sunny, then we got thunderstorms, so I planned to plant them the following morning.

I ordered six slips of four different types of sweet potato and I counted 9 – 12 slips of each type when I unwrapped the papers. This means I received many extra slips. I will not have space, I already know this. I was pushing it at 4×6=24 and now I have more like 40-45 slips.

I received more than 6 slips of each type of sweet potato.

The Potato Beds

Originally I had planned to clear some area in the yard to grow things like sweet potatoes. Now, I realize that raised beds work better. Controlling the soil and moisture is easier in a container. I’ve already successfully grown many things in my Vegega metal beds.

Over “winter” here in Florida I grew a lot of green beans. I planted them intermittently in all three raised beds. I knew the beans would be gone by the time I needed the beds for the potatoes.

The gardening goal is to always have something growing. Some Tulsi (holy basil) is growing, along with kale and random marigolds. I’m not worried about planting the sweet potatoes among these things. Most of them I pulled out, but it will be a while before the potatoes grow and take over the bed.

Sweet Potato Types I Planted

  • Beauregard
  • Bayou Belle
  • Covington
  • Purple Majesty

On June 16th, I put on my long UVskinz clothing to keep the mosquitoes off, and got outside by 8 AM. We still have not had enough rain, so every place I planted the slips needed to be watered. I had to add dirt to the bags and some beds. The temperature was 80 with 90% humidity, so it was super muggy to be gardening. I had no choice.

The potatoes were planted before the sun hit my yard, which made it bearable. But I was hot and dirty after a couple of hours of lugging dirt and planting. The leftover slips will go into my compost and I did manage to find space for a lot of the slips. By the end of September into October, I should be digging some potatoes.

I do not plan to have to order slips again. As long as the potatoes grow well, I can create my own slips for next summer. By the way, I believe you can order sweet potato slips early to be sure you get them. That is the way SESE does it.

Digging the Sweet Potatoes and Learning a Lesson

It’s the end of August and time to dig my sweet potatoes. I will not grow them in a raised be again, and here’s why.

The other day I spent quite a bit of time digging up my sweet potatoes. My bright idea was to use my new, long Vegega garden bed to grow them. I had just filled it with lots of stuff, along with dirt, and it really wasn’t good for growing much. So, I figured why not use it for sweet potatoes?

That was not a bad idea, because I don’t really have ground space for them. But when it came time to dig them, I had to kneel and dig by hand. A pitchfork is generally used to dig potatoes, but in the bed I couldn’t do that. It was a job.

I planted the potatoes back in February. They’ve been growing for 6 months.

I’m hoping that I got all of them and it’s a nice little haul. Plenty of sweet potatoes for me. Now they have to dry in a humid location – no problem there – for about 10 days. This toughens the skin for storage, and sweetens the potatoes.

The other problem with sweet potatoes is that they last forever. I mean the ones left behind in the dirt. Even roots will continue to grow and I bet I will see sweet potato vines in this bed for years to come!

Sweet Potato Slips Keep Showing Up

Sweet potatoes are not difficult to grow where I live. In fact, once planted, they may be around forever.

I’ve dug my sweet potatoes, but little shoots keep on sprouting. I’m finding them in the garden, and in the walkways. Any parts of the original plant, that have been hidden underground (roots) continue to grow.

Later…

Sweet potato vines are popping up in my walkways. The roots are left from the sweet potatoes I grew in that box last year.

Some of the vines have been added to fabric bags and one went into a pot (above).

I don’t think sweet potatoes are meant to grow over the winter. Pre-orders for slips take place during winter and the slips are shipped in Spring. They are a Spring-Summer crop. I will let these grow and see what happens. The leaves are edible and I will use them while I wait for the potatoes to grow.

The sweet potatoes I dug this year were small but I still have a few left to eat. Most were funny looking and not anything like what you buy in the store. But they taste delicious. One day I hope to have a raised bed just for sweet potatoes.

Sweet Potato Harvest in August

My sweet potato plant was ready to dig and I got a funny-looking, but excellent harvest.

Sweet potato slips were ordered and planted in my Florida yard this past April. I’ve read that they should be ready in 90 to 100 days. It’s August, and time to check for a crop.

One of the 12 slips, received back in April, was planted in a grow box. That plant did great! It had many vines sprawling everywhere all around the ground. I was able to eat the leaves in my salads as well. None of the other sweet potato plants, planted in the ground at the same time, look this nice.

Today, August 2, and it’s been over 100 days. I decided to dig and see if the potatoes were ready. The sweet potatoes (Beauregard variety) I harvested are not huge, but slim and long. I think they will be delicious!

The crooked ones formed because of the box. They were a bit packed in. This was not the ideal location to grow, but I’m happy with the amount that grew.

The Dig

It is exciting to have a harvest that comes from underground. Gardeners are unable to really see what is growing until it’s time to dig.

I loosened the soil and reached in with my hands and found the biggest potatoes just under where the slip was planted.

The grow box was emptied of dirt, which was full of roots – and more sweet potatoes! When I pulled up the black drain piece, I found three more potatoes at the bottom.

While pulling up the vines, many had rooted in the ground. I found a few more small potatoes while doing that. I’m emptying the box to create a better system for drainage. It also needs new dirt and amendments for whatever is planted next.

All the vines went into my Vegega raised bed. I’m using it as a compost pile until I can get some dirt. All these nice vines will help fill it.

Buying Sweet Potato Slips to Plant

Sweet potatoes grow from slips, which are little plants that are set into the ground. Nurseries grow them and ship them out when it’s time to plant in your location.

This past year I ordered from Annies Heirloom Seeds. I did not know when the plants would arrive. Minimum order was 12 slips, which I really didn’t have space for. Of course with my luck, they arrived right before I left for vacation for 2 weeks! I had company and then I flew north. I barely had time to get them into the ground, and a few I didn’t.

It was hot and rain-free while I was away – of course – and I couldn’t care for the little seedlings like I should have. Currently, I have only 7 more plants growing. They need longer to form the potatoes, so I’ll check them later in the season.

I plan to buy my sweet potato slips from SESE in December, which is when pre-ordering begins. I like that I can get only 6 slips instead of the 12 (minimum) at Annies. They ship to various locations when it’s time to plant and ship from mid-May to June. I plan to have some good beds or ground areas ready by then. This next year, I will be ready!

Curing Sweet Potatoes

I had to search for info on curing the potatoes and found it at Southern Exposure Seed Exchange. They have a page full of information, if you are wondering about how to care for slips, plant, grow, harvest and cure sweet potatoes.

They need heat, and they grow very well here in Florida, so northerners probably can’t grow them. I’d like to know.

I look forward to eating these potatoes. The garden is not giving me many crops in this heat, so finally having food is awesome!
