People obviously love eating potatoes, but growing your own is actually very simple. If you’re short on space, or if your garden is already full of other plants, you may wonder if you can still grow potatoes. With vertical gardening, you can grow the same amount of potatoes more easily and with less space. Here’s your simple guide to vertically growing potatoes in a way that works for you.
Potatoes don’t need much space horizontally to grow; a plot of one square foot is enough for a single potato plant. Just keep in mind that more plants means more room needed — and means more potatoes to harvest. Five square feet is a great middle ground, especially if you’re looking to harvest enough potatoes to feed a family.
Vertically, your garden will likely be one to three feet tall. The height of your garden can vary, as it depends on how tall your potato plants will grow. You may be able to coax them taller, depending on the variety and growing conditions. If your potato plants are stubborn, or if conditions aren’t quite right, you may end up with a shorter garden.
Measure out your base and lay your seed potatoes on the surface of the ground, spaced four to six inches apart. Don’t bury them, because you want your bottom layer to be above ground to make harvesting easier. Instead, layer a few inches of soil on top of your seed potatoes. Once the vines have grown about two inches, layer more soil onto them. You can also add a layer of leaves or straw instead of soil. Continue this process until your plants are between two and three feet tall.
Stop layering at this point and let the plants develop leaves. If you can see the tops of the tubers, cover them with soil. When exposed to sunlight, potato tubers can burn or turn green and produce a toxic chemical called solanine.
Vertical potato gardens resemble a tower, with the potatoes in the center surrounded by walls. There are many ways to craft your tower, with some choosing to build the walls up as the plants grow and others deciding to build the walls first. Putting the walls up first can save you some time overall and is easier to set up – but can result in a tower that is too large or too small. Building the walls as you go takes a little more time and effort, but your tower will be the right size every time.
A basic tower is made from wood boards, roughly the width of each layer, nailed together to form a box. The potatoes on the lower levels will be ready for harvest slightly sooner than the potatoes on higher levels. So, when it comes time to harvest, simply remove the bottom board on one side of the layer you’ll be harvesting.
You can make your tower in any way you’d like, based on what you have available. For example, a five-gallon bucket with the bottom cut out of it, an old laundry basket, or even just chicken wire on wooden posts. Having one side that is removable or made of wire can also make watering your tower much easier.
This method of growing potatoes is a great way to grow the same amount, or even more, potatoes in less space. If you have limited space, but still want a hearty harvest, this is an excellent option. It’s fairly easy to set up, and it’s easily customizable based on your needs and resources.
Harvesting potatoes is a messy process. This is true no matter what method you use. However, harvesting from a vertical garden can also be a little tricky and uncomfortable. The upper levels of your tower should be relatively easy to harvest, but the lower levels, especially the bottom level, may give you some trouble. This is especially true the first time you do it, although it does get easier with practice.
This simple method makes use of whatever extra space and supplies you have to provide you with plenty of potatoes. Whether you’re an experienced gardener looking to make use of the last corner of your garden or a beginner looking for a project that doesn’t need much space, vertical potato gardens are a fun way to grow as many potatoes as your heart desires.
