Step-by-Step: How to Grow Potatoes Indoors
1. Pick the Right Potato Variety
Choose smaller or early-maturing varieties like:
- Yukon Gold
- Red Norland
- Fingerlings
These perform better in containers and produce quicker yields. Compact, fast-growing varieties are ideal when your goal is to grow potatoes indoors efficiently.
2. Prepare Your Seed Potatoes
Cut seed potatoes into chunks (each with 1–2 eyes) and let them dry for 24–48 hours to prevent rot. You can skip this step if using small, whole seed potatoes.
3. Plant in a Deep Container
Fill your container with 4–6 inches of potting mix. Place your seed potatoes cut-side down, eyes facing up. Cover with 3–4 inches of soil.
Pro Tip: Use a fabric grow bag for better airflow and drainage—perfect for potatoes. These breathable containers are especially helpful when you grow potatoes indoors and want to avoid soggy soil.
4. Provide Plenty of Light
Potatoes need 12–16 hours of light daily. If sunlight is limited, invest in a full-spectrum grow light.
5. Water Consistently
Keep the soil evenly moist but not soggy. Stick your finger in the soil—if the top inch is dry, it’s time to water.
6. Hill the Potatoes
As sprouts grow to about 6 inches tall, cover them with more soil, leaving just the top leaves exposed. Repeat until the container is full. This encourages more tuber production.
Indoor gardeners who grow potatoes indoors love this step—it’s how you multiply your harvest in limited space.
7. Feed Your Plants
After 4 weeks, start feeding with a balanced liquid fertilizer every 2 weeks. Or use a homemade blend made from your kitchen scraps.
Harvest Time!
Potatoes are ready to harvest when the plant starts yellowing and dying back—usually around 10–12 weeks after planting for early varieties. Gently dump out your grow bag or container and dig through the soil to find your homegrown treasure.
You can also do a “sneak harvest” by digging out a few baby potatoes while the plant is still alive.
One of the best parts when you grow potatoes indoors is the convenience—harvest fresh, clean spuds without ever stepping outside.
How to Store Your Indoor Potatoes
- Cure them first: Leave in a cool, dark, well-ventilated area for 1–2 weeks to toughen their skins.
- Store in a paper bag or basket in a cool, dry place (not the fridge).
- Avoid storing near onions, which release gases that can cause sprouting.
How Much Can You Expect?
One 5-gallon container typically yields 5–10 potatoes, depending on the variety and care. Growing multiple containers at staggered times can provide a steady supply of fresh potatoes year-round.
If you plan strategically, you can grow potatoes indoors continuously and never run out of this pantry staple.
