If you don’t have the room in your garden to plant potatoes or even if you have no garden at all, you can grow potatoes in containers. Here are some tips for growing potatoes in pots, grow bags, and buckets.

Tips for Growing Potatoes in Containers:

1. Use large containers: The larger your container, the more room your plants have to stretch out their roots and form tubers. Consider the following:

  • Grow Bags: Grow bags are made from fabric. The fabric helps prevent over-watering and allows air to reach the roots. Grow bags tend to dry out quicker than other containers, so keep an eye on your plants watering needs. Consider these 5gallon grow bag to grow 2-3 seed potatoes, or these 10gallon grow bag to plant 4-6 seed potatoes.

  • 2. Use a lightweight soil mix: Potting mixes specifically made for containers will work. If you are mixing your own, a good mix is 1/3 good quality finished compost, 1/3 vermiculite or perlite, and 1/3 coconut coir or peat moss.

  • 3. Feed the plants: Add an organic granular fertilizer, such as plant tone to the container at planting time. Once the plants emerge from the soil, feed the foliage every two weeks with fish emulsion Spray the plants early in the morning to give the foliage time to absorb the nutrients and dry before the hot midday sun. Follow the instructions on the packages.

  • 4. Water well: Watering requirements of potato plants grown above ground are greater than in the ground. Since the soil is not insulated as well as in the ground, water evaporates quickly. The plants will stop growing if they become dry or overheated.

  • Check the containers frequently in warm weather by sticking your finger in soil. Water your pots if the top two inches of the soil feels dry. Water deeply until the water drains out the bottom holes so the moisture reaches the roots at the bottom of the container.

  • 5. Keep the tubers covered: Potatoes will develop areas of green skin when they’re exposed to direct sunlight during growth. The green areas are toxic and should be trimmed away. Prevent your potatoes from forming green skin by covering with soil or mulching heavily so no light reaches the tubers.

  • 6. Grow potatoes in full sun: Potatoes thrive with at least 6-8 hour of sunlight per day. However, potatoes are a cool season crop that doesn’t like the heat. The plants may stop growing once temperatures reach the high 80s˚F. So if your weather is warm, try to locate your containers in an area that receives morning sun, then is partially shaded during the afternoon.
