How to plant potatoes and sweet potatoes in old garbage cans (large), barrels and old bathtubs.

Evening people. I'm looking for more ways to grow more potatoes or sweet potatoes to produce as many as I can for myself, my folks and everybody else to have. How wide are the plants if being grown in a tub or garbage can, and how many tubers would one plant produce to have for one or more people? I've never grown potatoes in a garbage can or any other large container, but It'd be a sustainable thing to do. I'd like to see some pictures, examples of what the plantings would look like in any large container including an old tub or barrel. Do they require some type of care after they been planted in them? All questions and feedback are welcome on this post for exchange of ideas and stuff. Adios!

I like a suggestion that I saw someone here on the forum said to plant in cardboard boxes.

When you are ready to harvest you just pick up the box and the potatoes fall out the bottom.

This might not be a sustainable way with sweet potatoes so your idea might be better for those.

I'm actually trying something new this year with my potatoes. Since I was able to pick up some wire fencing for free (It's crazy what people throw away and then think I'm crazy for getting excited about it!!!), I dug out some grass, placed my seed potatoes down, threw some compost and shredded leaf mulch over them, and made a ring around them with the fence. Plan on just covering the plants with more leaf mulch and straw as they grow.

Anne, I saw that post as well and am really intrigued by it as well. I might just give that method a try as well if I have some more potatoes start to sprout. I wonder how well it would work indoors with a grow light; get some fresh spuds during the winter!

I planted potatoes in tubs last evening, for the first time ever, will see how they do. I do web site work for a small winery that buys concentrated juice in 55 gallon drums and they gave me some, I just cut them in half and filled them abut 1/3 full of partially composted wood chips and soil and put the potatoes in, as they grow, I'll add more compost until it gets to the top. I drilled holes in the edges at the top and attached rope to serve as handles, theory being I'll be able to just dump them out to harvest, I hope it goes well, I'll see I reckon.

Sweet potatoes are a different story. I've been growing and breeding them from true seeds for about ten years.

One of the things I've focused on is for adaptation to growing in relatively small containers. They have a wide range of growth habits. On some the roots are very spreading, the storage roots (sweet potatoes) may form anywhere along the feeder roots. These do not do well in containers, as the feeder roots will exit the container through the drain holes and the sweet potatoes will form deep in the ground or far from the actual containers. If growing this type in containers, they would have to be very large.

A trait I call clump root, and that I have been selecting for, is when a nice cluster of sweet potatoes from immediately beneath the plants primary stem.  These also tend to have a bushy non-spreading vine growth habit. My bushy, clump root line produces very well in pots as small as three gallons. *The feeder roots still exit the drain holes, so it is important to bury the pots to above any side drain holes and not to move them once plants are established. If they are moved and the feeder roots broken, then it becomes necessary to frequently water and feed compost tea in order to produce a nice harvest.

I don't know about potatoes, but my sweet potatoes are easily adapted to growing as houseplants or in a green house. A warm south facing window is all that's needed to produce a continuous supply of greens all season long. My house is quite small and window space is at a premium, so I haven't experimented a whole lot with producing actual sweet potatoes inside but from some limited observations I'm fairly confident that is doable as well.

I expect in the spring of 2024 or perhaps this fall to be offering my sweet potatoes for sale as clones and perhaps also as seeds.

It's great to see that you're interested in propagation tips and tricks for growing potatoes and sweet potatoes in a tub or garbage can. This is actually a really cool and sustainable idea!

In terms of the width of the plants, it really depends on the size of the container. Generally, you want to give each potato plant enough space to grow and develop, so you should space them out by about 12-18 inches in all directions. As for how many tubers each plant can produce, that can vary as well, but typically you can expect to get anywhere from 5-10 tubers per plant.

I don't have any pictures to share at the moment, but there are plenty of examples online of how to plant potatoes in large containers like old tubs or barrels. Just make sure that the container has adequate drainage and that you're using a good quality potting mix. As for care, you'll want to keep the soil consistently moist but not waterlogged, and you can also add a slow-release fertilizer to help keep the plants healthy.

I hope this helps, and happy planting! Let us know how it goes and if you have any other questions. Take care and adios!
