Hey there, fellow gardening enthusiasts! I'm stoked to share some insights on a question I get asked a lot: "Can I grow potatoes in a 20 gallon grow bag?" As a supplier of 20 Gallon Grow Bags, I've seen firsthand how these bags can transform your gardening game, especially when it comes to growing potatoes.
First off, let's talk about why a 20 gallon grow bag is a great choice for growing potatoes. Potatoes are a root vegetable that needs plenty of space to spread out and develop those delicious tubers. A 20 gallon grow bag provides just the right amount of room for the potato plants to thrive. It's not too small like a 5 Gallon Grow Bag, which might restrict the growth of the potatoes, and it's not too large like a 30 Gallon Grow Bag, which could be overkill for a single potato plant or a small group of them.
One of the key advantages of using a 20 gallon grow bag is its portability. You can move it around your garden to find the perfect spot with the right amount of sunlight. Potatoes love full sun, so make sure to place the grow bag in an area that gets at least 6-8 hours of direct sunlight per day. And if the weather gets too hot, you can easily move the bag to a shadier spot to protect the plants.
Another great thing about grow bags is their excellent drainage. Unlike traditional pots or garden beds, grow bags allow excess water to drain out easily, preventing waterlogging and root rot. This is crucial for potato plants, as they don't like to sit in wet soil for too long. The fabric material of the grow bag also allows for better air circulation around the roots, which helps keep the plants healthy and promotes strong growth.
Now, let's get into the nitty-gritty of actually growing potatoes in a 20 gallon grow bag. The first step is to choose the right type of potatoes. There are many different varieties available, each with its own unique flavor and texture. Some popular choices for growing in containers include Yukon Gold, Red Pontiac, and Fingerling potatoes. You can buy seed potatoes from your local garden center or online.
Once you have your seed potatoes, it's time to prepare the grow bag. Fill the bag about one-third full with a high-quality potting mix. You can also add some compost or aged manure to the mix to provide extra nutrients for the plants. Make sure the potting mix is well-draining and loose.
Next, it's time to plant the seed potatoes. Cut the seed potatoes into pieces, making sure each piece has at least one or two "eyes" (the small bumps on the surface of the potato). Let the cut pieces dry for a day or two to prevent them from rotting in the soil. Then, place the potato pieces on top of the potting mix in the grow bag, spacing them about 6-8 inches apart. Cover the potatoes with another 2-3 inches of potting mix.
As the potato plants grow, you'll need to keep adding more potting mix to the grow bag. This is called "hilling" and it helps to encourage the plants to produce more tubers. When the plants are about 6-8 inches tall, add another 2-3 inches of potting mix to the bag, covering the lower part of the stems. Repeat this process every few weeks until the grow bag is almost full.
Water the potato plants regularly, making sure the soil stays moist but not waterlogged. You can use a soaker hose or a watering can to water the plants at the base. Avoid getting the leaves wet, as this can increase the risk of diseases.
Fertilizing the potato plants is also important. You can use a balanced fertilizer, such as a 10-10-10 or 12-12-12 formula, every few weeks during the growing season. Follow the instructions on the fertilizer package for the correct application rate.


One of the great things about growing potatoes in a 20 gallon grow bag is that it's easy to harvest them. When the potato plants start to turn yellow and die back, it's a sign that the potatoes are ready to be harvested. Carefully remove the potting mix from the grow bag and gently dig out the potatoes. You can use your hands or a small garden fork to do this. Be careful not to damage the potatoes.
So, there you have it! Growing potatoes in a 20 gallon grow bag is a fun and rewarding way to enjoy fresh, homegrown potatoes.
