Step-by-Step Guide to Planting Seed Potatoes in a Bag

Expert Tips for a Bountiful Bag Potato Harvest

• Use the right soil: A light, well-draining potting mix with added compost works best. Heavy garden soil compacts in bags and reduces yields.
• Sunlight: Place your bag in a sunny spot (at least 6 hours of direct sun daily). Potatoes love warmth and light.
• Pest watch: Keep an eye out for aphids. Use a natural soap spray if needed. For more organic pest control tips, check our natural pest control guide.
• Rotate your bags: If you grow potatoes in bags every year, refresh the soil and avoid disease by using fresh potting mix each season.

Harvesting and Storing Your Bag-Grown Potatoes

Once the foliage has completely died back, your potatoes are ready. Here's how to harvest and store them properly:

• Harvest: Tip the bag onto a tarp or into a wheelbarrow. Gently sift through the soil to collect all the tubers. Avoid bruising them.
• Curing: Spread the potatoes in a single layer in a dark, well-ventilated area at 60-65°F for 10-14 days. This toughens the skin for storage.
• Storage: Store cured potatoes in a cool (40-50°F), dark, humid place. A basement or root cellar is ideal. Never refrigerate, as cold converts starches to sugars.
