Have you ever looked over your crowded garden and wished you had the space to grow more? I know, like every week, right! That’s why we wanted to share our experience of growing crops in temporary containers, or more to the point… reusable grow bags.
If you want to start a vegetable garden on your patio, balcony, or squeeze a bit more yield out of a plot with poor-quality soil, then you definitely need to buy yourself a few good quality potato grow bags. They’re free-draining have good aeration, and portable, helping you to get the best available sunlight. They really are a simple and rewarding approach to growing more.
I’m going to provide you with some useful tips on growing potatoes in bags and share my review of the 10 best potato bags available online.
Growing Potatoes In A Bag
There are plenty of benefits to growing potatoes in grow bags. When I say grow bag, I’m not talking about the long pillow-shaped bags that you grow tomatoes in your greenhouse. These are upright barrel-shaped grow bags, that use very little space relative to the potential crop yield they can produce. So in terms of performance, bags are a great option.
You also have the convenience of taking a no-dig approach, just fill the bag with compost and grow. This in itself brings another advantage…you control the quality of the growing medium. No need to worry about clay soil or stones. You are in total control, and when you’re done, just clean the bag, fold it and pack it away until next spring.
To grow your potatoes in bags, all you need is the grow bag, seed potato, and compost, and within 12 weeks you could be harvesting a beautiful crop of tender new potatoes.

10 Best Potato Grow Bags Reviews
In this review, we will take a close look at the best potato grow bags on the market. Our recommendations are based on the construction of the bag and its durability, appearance, and overall functionality and features. We also share customer feedback collected from major retail platforms and gardening forums, to help you make the right decision when buying your grow bag.
Made of breathable double layer cloth, this 4-pack of potato grow bags from Homyhoo provides your plants will good ventilation whilst preventing the build-up of excess moisture. These 10 gallons grow bags are big enough to grow up to 3 maincrop potato plants or 5 early varieties. This model is fabricated from a strong felt-like material that has proven very durable over the two seasons we’ve been using them.
The lift flap positioned on the front of the grow bag is intended to be a ‘harvesting window’. Where you can reach in and take a few tubers as you need them. In practice, you’re better off harvesting all of your potatoes at once when they are ready. Hardening them off in the traditional way and storing the crop in hessian sacks until needed.
I particularly love the durability of the fabric, it’s well made, good stitching, and strong handles allowing you to move it if required. Which I often do, as I chase the sun as the season progresses. Find these on Amazon.com.
Customer reviews: users found the grow bag very easy to move around, highly durable with a good capacity to grow not just potatoes but also other vegetables.
- Strong and durable fabric

You will notice this design is more pot-like, and as we move towards the larger-sized containers, and they have a wider open structure. This shape is slightly easier to handle and get access to whilst planting seed potatoes and earthing-up.

Again this model comes with the easy harvest window on the side which has several uses; keep an eye on your tubers growing throughout the season, or harvesting a few potatoes at a time.
Delxo bags have good drainage and are perfect for smaller early varieties of potato, but also super for tomato’s, chili, and other crops. You won’t need to worry about damaging your potato roots with standing water, as these bags are designed to allow natural drainage and good aeration. However, I do tend to put a few extra drainage holes in the bottom of all of the grow bags I have used. I just prefer it that way.
Customer reviews: users were pleased with how well these bags hold up in all weather conditions, over several growing seasons
- Easy to set up and a reusable bag
- Small enough to move around with ease

What we particularly like about these grow bags is their sturdy, double stitched handles with straps that make moving easy and safe. Buy them here online.
Customer reviews: some users complained of mold growth developing on the outside of the pots. One way to overcome this issue is to add more holes to the side and bottom in order to increase ventilation.

Here we have a 4 pack of 10-gallon grow bags from Tanzfrosch available from Amazon.com. You may have noticed these are the only plastic bags on our list, not for any reason other than most bags on the market are fabric, but each material has its pros and cons. Plastics tend to hold moisture better but reduce airflow. So before you choose your material just give that some consideration. Both materials are good when used in the right way.
The grow bags are made from strong and durable polypropylene plastic, with handles located on either side allowing you to easily move them when filled. These bags have built-in drainage holes that prevent the soil from getting waterlogged.
Simply fold the bag and put it away until next year when the growing season is over!

These rather unique grow bags from Chepula definitely stands out from all the other bags on the market. This is thanks to its side zipper design that makes it easy to grow potatoes and inspect or tend to them with minimal disturbance. Soft rubber handles are a nice feature offering more protection when lifting.
The lightweight and waterproof material of these 7-gallon bags make them suitable for both indoor and outdoor gardening. They were great to use but only time will tell how durable the zipper mechanism is in a grow bag. I have seen some gardeners using them as storage compartments in their greenhouse or shed, which is also a great idea. Keep your Perlite, Compost, or spare pots in there.
Customer reviews: users particularly liked the fact that they can open the bag from the side using the convenient zipper. Pleasingly, even after using the bag for a whole season outdoors in both rain and sun, the grow bag is still going strong. Buy them online here.
- Well-draining bags
- Good quality fabric
- Sturdy design
- Zipper may prove the weak link over a few seasons use
These award-winning growing pots sold as a pack of 3 by UK brand Garden of Life, actually came best in class at the 2015 Chelsea Flower Show. Okay, not a grow bag, but well worth a notable mention. This product is only available in the UK at Amazon.co.uk.
Measuring 25-cm high and 30-cm in diameter, these growing pots feature an inner and outer container that make growing potatoes really simple. The window of the inner pot means you lift it from the outer pot to monitor the growth of your plant or to harvest a few potatoes as and when they’re ready. It’s a great way to take the guesswork out of harvest time.
Lightweight, decorative, and relatively compact, you can position these pots in smaller spaces as they won’t take up much room. Another great option for smaller potato crops.
Customer reviews: users found these colored grow pots very easy to assemble and even easier to plant potatoes in. They are light enough to carry even when full. They also have excellent drainage.

When growing a potato crop having direct sunlight on your tubers will turn them green. So this bag offers a band of black-out fabric to remove the light until you want a peek. So when growing potatoes be sure to use them.

- Blackout panels block light to protect certain crops from sunlight
- Visualization panel may wear over multiple seasons
How To Plant Potatoes In A Bag
Before planting seed potato I would always recommend chitting, to give them the best possible start.
Place your seed potatoes in an old cardboard egg tray and leave them in a bright spot, out of direct sunlight.
Over the next two or three weeks, you will see the potato sprout small white shoots that develop a green head. This is the start of the foliage sprouting in search of sunlight.
Planting and Earthing Up
- When your chit potato has sprouted, prepare your grow bag in the location you wish to grow them to avoid moving them later
- Roll-down the sides of the grow bag as if you were rolling up your sleeves. This will avoid the planted potato seed being shaded from sunlight, and offer them maximum sunshine allowing a strong start
- Fill the bottom of the grow bag with compost to a depth of around 6-8 inches
- Place your seed potatoes at least two inches under the compost surface. Be sure to point the sprouted end upwards, as shown in the picture above
- Water them in, and keep an eye on them over the next few weeks making sure they are kept watered to avoid the compost drying out
- Continue to water well throughout the growing season for the best tubers. Potato plants are thirsty
As the potato plants begin to break the surface of the compost they will grow pretty fast. Each time you have around 6 inches of green foliage you will need to unravel the potato bag so it is above the tips of the foliage and ‘earth up’ your potatoes by covering them gently with more compost.
Earthing up will continue until the plants are fully grown and the potato grow bag is 3/4 full of compost. This process allows the plant to grow in a nice healthy manner with optimum sunlight exposure, whilst making the most of the grow bags soil capacity and growing space.
When the plant matures you will have a mass of potato tubers throughout the whole compost volume.
Best Compost For Potato Bags
Potatoes can be grown in almost any soil type so try not to make it too complicated for yourself. For optimal growth, the soil should have a pH level of between 5.2 and 6.4, be nice and loose, and the richer the better for large healthy tubers.
Use a multi-purpose compost or a peat-free compost. If you have it, add some well-rotted manure or homemade compost. Keep the soil light and free draining with plenty of drainage holes in the bottom of your grow bag.
Considering potatoes are root vegetables, they can also benefit from an all-purpose fertilizer of 8-24-24 or 5-10-10 formula. But usually, this isn’t necessary if you have used a good quality compost or a compost tea feed.
How Long Does It Take To Grow A Potato In A Bag
How long it takes to grow your potatoes depends on the type of potato you want to grow. There are 3 main potato varieties, each with its own maturation time.
- First Earlies: Also known as new potatoes, plant from March onwards after the frost. Matures within 10-12 weeks
- Second Earlies: Plant from March onwards after the frost. Matures within 14-16 weeks
- Maincrop: Plant from April onwards or after the frost has passed. This crop will mature in 16-22 weeks
The growing period largely depends on the variety you’re growing. That said, allow between 70-120 days from the time of seeding to harvesting. You can start your grow bags in your greenhouse or patio as early as February before moving them outside after frost has passed.
When To Stop Watering Potatoes
Once your potato plant has flowered through the end of the growing season, the leaves will start yellowing and its stems will wither. This is when you should stop watering and wait around two weeks before harvesting your potatoes.
Best Potato Growing Bags Conclusion
We made our selections based on the best potato growing bags that are currently available on the market so you can buy any of this in confidence knowing they are tried and tested and they all delivered great results.
If you’re still unsure, just think about what your priorities are. If you want high yields then go for a larger fabric bag of 20-30 gallons.
