Step 5: Selecting a Suitable Container

Potatoes are not picky about their growth container. You can use various options such as trash cans, compost sacks, or burlap bags. One preferred method is growing potatoes in 40-gallon grow-bags. No matter which container you choose, follow the fundamental planting principles outlined below to ensure success.

Step 6: Planting the Potatoes in Containers

Pair the quantity of seed potatoes with the size of the container to avoid overcrowding. As a basic rule, each potato plant requires approximately 3 gallons of space to grow optimally. Overcrowding may result in smaller potatoes.

Add a 3-4 inch layer of loose soil mixed with compost at the base of the container. Potatoes thrive in slightly acidic soil, so consider using a soil mix formulated for acid-loving plants or enhance your soil with an acid mix fertilizer following package instructions.

Step 7: Properly Water the Potatoes in Containers

Consistent moisture is essential for potato growth in containers since they cannot draw moisture from the surrounding soil. Consider using a drip line inserted in each grow bag for uniform watering. It’s crucial to maintain soil that’s evenly moist but not soaked. Allow some drying between watering sessions.

During the growing season, consider supplementing actively-growing potatoes with an acid-loving organic fertilizer or seaweed extract each time you add more soil. A layer of straw can also help retain moisture.
