What to know before you buy a potato grow bag

Potato grow bags are fairly straightforward. They are malleable bags — usually fabric — in which you can plant your potato plants. Because the bag is flexible, it allows for a more natural root system. Instead of spiraling around the bottom of a pot, the roots can continue to grow out and unbound. 

The healthier, stronger root system will lead to more tubers and a more fruitful potato harvest. When they’re ready, you can easily harvest them out of your grow bag, especially if you get one with a harvesting window. 

Using your potato grow bag is as simple as potting the potato plant in a traditional pot. Start by adding a couple of inches of soil or compost to the bottom of the bag. Place your seed potatoes in the soil and fill the bag with enough to barely cover the tops of the seed potatoes. For easier handling, you can roll the top of the bag down to just above the top of the soil. 

Keep your soil and seed potatoes evenly moist. As they start to sprout, continue to add soil or compost to cover the sprouted potato greens. As you add soil, unroll the bag. Eventually, the soil will reach the top of the bag. 

At that point, let your potato plant flower and die back. After that, you can harvest your tubers. If you have a bag with a harvest window, simply open the harvest window and pull out the potatoes you want. If your bag doesn’t have a harvest window, dump it out and start digging. 

As you consider which potato grow bag to plant your crop in, keep a few things in mind. 

Size

Potato grow bags come in a range of sizes, typically by gallon. While a 5-gallon potato grow bag may look small and easy to move around when it’s empty, once you fill it with 5 gallons of soil and potatoes, it will be much heavier. Consider how much you can lift and move before committing to a bag that’s too big. 

Material

Different potato grow bags are made of different materials. While the general structure of a potato grow bag is almost universal, the difference in the material will determine where you should place your grow bag. If you have a grow bag that’s rated to last for several years and is highly durable, feel free to leave your crop outside. If it’s a fabric that is less durable, plan on keeping your potato crop indoors away from the elements. 

Maintenance

Although a grow bag can seriously improve the root system of your potato plants and lead to an enviable harvest, planting your potato plants in grow bags is signing yourself up for some extra maintenance. For example, you’ll have to water your crop more often than you would otherwise because of the improved drainage and airflow. 

Another maintenance task is repotting your plants. Because the bags aren’t as durable as a ceramic or stone pot, you will likely have to repot your plants more often than you’re used to. If you want less maintenance, reconsider a grow bag. If you’re OK committing a little more time to your plants, a grow bag is the way to go. 

What to look for in a quality potato grow bag

Handles

One of the best parts of gardening in grow bags is the portability. You can move them inside at the first sign of frost or run them outside to get a drink of fresh rainwater. Something that makes all that moving easier is a set of handles. Look for a grow bag that has handles if you don’t want to break something trying to move your potatoes. 

Harvest window

Arguably one of the most highly prized features in a potato grow bag is the harvest window. This allows you to harvest only the potatoes you want as needed without dumping out the entire bag. You can also check up on the root system easily using the harvest window. 

Nonwoven fabric

Most of the best fabric grow bags are made with nonwoven fabric. This creates far better drainage and ventilation. Because the roots are more free in a grow bag, they benefit from improved drainage and ventilation, leading to stronger, healthier growth, which in turn leads to a larger harvest. 

BPA-free

If you get a bag made of plastic-based fabric, be sure it’s BPA-free. If it isn’t, you risk your bag leaching chemicals into your potato crop. The packaging should have a clear label identifying the bags as BPA-free. 

Lightweight

Once you add the soil and potatoes, your potato grow bag will become heavy. If it is heavier than it needs to be, you’re just adding to the weight you have to move around. The best grow bags are lightweight yet durable and strong. Always check the weight of the bag before you buy it. 

How much you can expect to spend on a potato grow bag

You can find a pack of grow bags for $10-$40. Where it lands in that range depends on the number of bags in the back and the quality of the bags. On average, a potato grow bag costs about $4 each. 

FAQ

How often can you harvest potatoes from a potato grow bag?

A. You can harvest your potatoes as soon as the tubers are mature, which happens after the potato plant has flowered and died back. Once that happens, you can dump out the bag and dig for your potatoes. If you use a grow bag with a harvest window, you can harvest potatoes as needed, possibly even year-round if you keep them indoors. 

What’s the benefit of potato grow bags?

A. The biggest benefit is to the root system of the potato plant, thanks to the improved drainage and airflow around them. In general, the root system has more of a chance to grow naturally, leading to an overall healthier plant and a better crop of potatoes. Plus, when the time comes to harvest your crop, it’s incredibly easy with a grow bag. You simply dump it out or use the harvest window. 

Are there any drawbacks to using potato grow bags?

A. Depending on how much work you want to put into your plants, a grow bag may not be for you. They do require you to water your plants more because of the increase in drainage and airflow. They’re also not as durable as traditional pots, so the cost of replacing them can add up. Plus, with all the soil and potatoes in them, the bags get incredibly heavy and may be more difficult to move than you initially thought.
