- Potting soil
- Seed potatoes
The Container: You can grow potatoes in any large container. I’ve seen potatoes grown in big garbage cans or even trash bags or stacks of tires. I would be cautious however, about using tires or trash bags because they can get very hot in the sun and also, the jury is still out on the potential toxicity of some of the plastics and rubber, which as they break down, might leach chemicals into the soil.
Another great way to grow potatoes in containers is in a "potato condo."
Whatever you use for a container, make sure it has good drainage. If your container doesn’t come with drainage, make sure to add some.
I love to grow potatoes in Smart Pots . They are lightweight, environmentally friendly and they are made of fabric, so your potatoes get air as they grow. Another advantage of Smart Pots is that they have great drainage so your potatoes will never sit in water and rot.
Potting soil: Use a high quality potting soil. If you are using a Smart Pot you can also use gardening soil mixed with compost. I like to use organic potting soil. If you are using a plastic container, make sure to use a soil that is fast draining.
Fertilizer: I use an organic slow release fertilizer which I mix into my potting soil. Also, as the potatoes grow, I use diluted liquid fertilizer, like fish emulsion, every couple of weeks.
SUN AND WATER: Potatoes will not grow without sun and water. You will need at least 6-8 hours of sun a day. Your potatoes also need consistent water to grow. You want to keep the soil moist, not wet. If the soil is too dry the plants will die. If it’s too wet, the potatoes will rot. If the moisture level is inconsistent, your spuds will be misshapen
