How to Grow Mini Potato Tubers in a Pot
What You’ll Need
- Mini potato tubers (whole, uncut)
- Large pot (at least 12–16 inches deep, 15–20 gallons) with drainage holes
- Potting mix (light and well-draining)
- Compost or balanced fertilizer
Step 1: Prepare the pot
- Make sure your pot has drainage holes.
- Fill the bottom 6–8 inches with potting mix.
Step 2: Plant the tubers
- Place the mini tubers on the soil surface, eyes facing up. Space 4-6 inches apart.
- Cover with 3–4 inches of soil.
Tip: Don’t bury them too deep—more soil will be added as the plants grow.
Step 3: Water
- Water gently to moisten the soil.
- Keep the soil consistently damp but not soggy.
Step 4: Add soil as plants grow (“hilling”)
- When shoots reach 6–8 inches tall, add 3–4 more inches of soil, leaving the tips exposed.
- Repeat until the pot is nearly full.
Step 5: Care during the season
- Place the pot in full sun (6–8 hours/day).
- Water regularly to keep soil evenly moist.
- Fertilize lightly if your potting mix doesn’t already contain compost.
Step 6: Harvest
- For baby potatoes, harvest when plants flower.
- For full-size potatoes, wait until the foliage dies back.
- Carefully dig or tip out the pot to collect your tubers.
