Growing potatoes in containers is a great way for gardeners with limited space to enjoy fresh potatoes. Potatoes are remarkably adaptable and can thrive in a wide variety of environments as long as they have enough room to grow. This guide will walk you through the process step by step, from choosing the right container and potato variety to harvesting your crop. Let’s look at the best practices for growing potatoes in containers to ensure a bountiful harvest.
1. Selecting your container
The first step is choosing an appropriate container. Potatoes need depth to grow, so your container should be at least 12-15 inches deep. Larger containers will accommodate more seed potatoes, increasing your yield. Common options include:
- Fabric plant bags : These are ideal as they are breathable, promote air circulation and prevent overheating. Their handles make them easy to move.
- Plastic or wooden containers : Make sure they have adequate drainage holes in the bottom to avoid waterlogging.
2. Selection of potato varieties
When it comes to growing in containers, not all potatoes are created equal. Look for early-maturing varieties like ‘Yukon Gold,’ ‘Red Pontiac,’ or ‘Purple Majesty.’ Seed potatoes are preferable to supermarket potatoes, which may have been treated to prevent sprouting.
3. Prepare seed potatoes
Cut larger seed potatoes into pieces, making sure each piece has at least one or two eyes (sprouts). Let the cut pieces rest at room temperature for a few days to allow the cuts to heal and form a protective layer that reduces the risk of rot.
4. Soil and planting
Use a high-quality potting soil designed for vegetables. Avoid garden soil, as it can be too dense and harbor pests. Fill your container with about 6 inches of soil, then place your seed potatoes on top, about 12 inches apart. Cover with another 3 inches of soil.
5. Watering and feeding
Potatoes require consistent moisture, especially when the plants are flowering and tubers are forming. Water your container potatoes to keep the soil moist but not soggy. Add a balanced slow-release fertilizer at planting time and consider a liquid feed every few weeks to encourage growth.
6. Grounding
As the potato plants grow, add more soil to the container, covering the stems but leaving the top few inches of the plant exposed. This process, called “earthing,” encourages the formation of more tubers along the buried stem and prevents the potatoes from being exposed to sunlight, which can turn them green and toxic.
7. Pest and disease management
Keep an eye out for common pests such as aphids and Colorado potato beetles. Even when growing in containers, practice crop rotation by not planting potatoes in the same soil for at least three years. Remove diseased plants promptly to prevent the spread of infection.
8. Harvest
Early varieties can be harvested about 10 weeks after planting, once the flowers bloom. For larger potatoes, wait until the leaves turn yellow and die. Dig the soil carefully to harvest your potatoes, being careful not to damage them.
9. Storage
Let your harvested potatoes dry in a dry, dark place for a few days to strengthen the skin. Once cured, store them in a cool, dark, well-ventilated place. If stored properly, your potatoes will last for several months.
