Do you love potatoes like I do? Well I do, but my wife does not. But that’s neither here nor there. A fun fact about potatoes: the city I grew up used to have a saying about that “we were a great place to grow potatoes.” Apparently the soil here is perfect for it. But have you ever wondered if you can grow potatoes indoors? It sounds crazy, but growing potatoes indoors can be a fun and rewarding experience, especially if you don’t have access to an outdoor garden. With a bit of planning and care, you can enjoy a bountiful harvest of homegrown potatoes right in the comfort of your home. This beginner-friendly guide will walk you through the steps to successfully grow potatoes indoors.
Why Grow Potatoes Indoors?
There are several reasons why you might want to grow potatoes indoors:
- Space Constraints: If you live in an apartment or have limited outdoor space, growing potatoes indoors allows you to enjoy fresh produce without needing a garden.
- Control Over Growing Conditions: Indoor gardening gives you greater control over the environment, including temperature, light, and moisture, ensuring optimal conditions for potato growth.
- Year-Round Harvest: By growing potatoes indoors, you can have a continuous supply of fresh potatoes throughout the year, regardless of the season.
What You’ll Need
Before you start, gather the following supplies:
- Seed Potatoes: Choose certified seed potatoes from a garden center or online supplier. I really like buying from True Leaf Market. It is preferred to avoid using store-bought potatoes, as they may be treated with chemicals to prevent sprouting, but if you do, try to buy organic.
- Containers: Use large pots, buckets, or grow bags with drainage holes. Each container should be at least 12 inches deep and wide.
- Potting Mix: Use a high-quality, well-draining potting mix. You can also add compost or organic matter to enrich the soil.
- Grow Lights: If you don’t have access to natural sunlight, use LED grow lights to provide the necessary light for your potatoes. Check out our page on grow lights here
- Watering Can: To keep the soil consistently moist.
- Fertilizer: Use a balanced fertilizer to support healthy plant growth.
Step-by-Step Guide to Growing Potatoes Indoors
- Prepare the Seed Potatoes
- Chitting: Before planting, allow your seed potatoes to sprout. Place them in a cool, bright location for a few weeks until they develop short, green sprouts. This process is called chitting and helps promote faster growth.
- Cutting: If your seed potatoes are large, you can cut them into smaller pieces, ensuring each piece has at least one or two sprouts. Allow the cut pieces to dry for a day or two to form a protective callus.
- Prepare the Containers
- Drainage: Ensure your containers have adequate drainage holes to prevent waterlogging.
- Soil: Fill the bottom of the containers with about 4-6 inches of potting mix. This initial layer provides a base for the potatoes to grow.
- Planting the Seed Potatoes
- Spacing: Place the seed potatoes, cut side down, on the soil surface. Space them about 6 inches apart to give the plants room to grow.
- Covering: Lightly cover the seed potatoes with an additional 2-3 inches of potting mix. As the plants grow, you’ll need to add more soil to keep the developing potatoes covered.
- Providing Light
- Natural Light: Place the containers in a sunny location, such as a south-facing window, where they can receive at least 6-8 hours of direct sunlight daily.
- Grow Lights: If natural light is insufficient, use LED grow lights to supplement. Position the lights about 6-12 inches above the plants and keep them on for 12-16 hours a day.
- Watering and Fertilizing
- Consistent Moisture: Keep the soil consistently moist but not waterlogged. Water the plants when the top inch of soil feels dry to the touch.
- Fertilizing: Apply a balanced fertilizer every 3-4 weeks to provide essential nutrients. Follow the manufacturer’s instructions for proper application rates.
- Hilling Up
- Adding Soil: As the potato plants grow and reach about 6-8 inches in height, add more potting mix around the stems, leaving the top few inches of the plants exposed. This process, called hilling up, encourages the production of more tubers.
- Repeat: Continue to hill up the soil every few weeks until the container is full.
- Monitoring and Maintenance
- Check for Pests: Keep an eye out for common pests such as aphids and spider mites. Use organic insecticidal soap if needed.
- Temperature Control: Maintain a consistent temperature between 60-70°F (15-24°C) for optimal growth.
- Pruning: Remove any yellow or damaged leaves to keep the plants healthy.
- Harvesting Your Potatoes
- When to Harvest: Potatoes are ready to harvest when the plants begin to flower, and the foliage starts to yellow and die back. This typically takes about 10-12 weeks.
- Harvesting: Gently dig into the soil with your hands or a small garden fork to find the tubers. Be careful not to damage the potatoes during the process.
- Curing: After harvesting, allow the potatoes to cure in a cool, dark, and well-ventilated area for a week. This helps toughen their skins for storage.
Tips for Success
- Choose the Right Varieties: Some potato varieties are better suited for indoor growing. Look for early-maturing or dwarf varieties that don’t require a lot of space.
- Rotate Crops: If you plan to grow potatoes indoors continuously, rotate the crops to prevent soil depletion and disease buildup.
- Regular Monitoring: Check your plants regularly for signs of stress, pests, or disease. Prompt action can prevent problems from worsening.
