How to Grow Potatoes in Containers

Nothing beats homegrown potatoes! I mean, that can be said about pretty much all organic homegrown produce… but homegrown potatoes are somethin’ special. No grocery store potato can even come close to the rich, earthy, creamy, complex flavor profile of a homegrown spud. The great news is, they’re also quite easy to grow! With the right conditions, you can be harvesting and enjoying your own homegrown potatoes in no time too!

Read along to learn how to grow potatoes in containers, including their soil needs, sunlight, water, and temperature preferences. We’ll also discuss options for obtaining potato seed, and how properly to prepare it for planting.

There are several ways to grow potatoes, such as in hills in the ground, in a raised bed, inside a wire fence cylinder, or even trash cans! Most of the tips and information I will share here today can be applied to any growing style. We personally love to grow potatoes in fabric grow bags because of their excellent drainage, mobility, ability to control the soil condition and moisture, and ease for harvest. The ones we love and use are very durable, and can be reused for years and years!

At the end of this post, check out the video about how to grow potatoes that goes along with it!


  • Seed Potatoes
  • Soil –  Rich, loose, well-draining, and acidified if possible
  • Container(s) – We use 15-gallon or 20-gallon grow bags. They can be used to grow food even in the most limited garden spaces!
  • A sunny location
  • Consistent water
  • Optional: Straw

Let’s start with the part that makes the rest possible: seed potatoes.

Seed Potatoes

You can either buy potatoes that are specifically sold as seed, or try your hand at sprouting and growing store-bought potatoes. Generally, you’ll have the most guaranteed success with seed potatoes. They’re grown specifically for this task, and are certified to be disease-free. They often times even come slightly pre-sprouted for you! You will also have more options to find and grow unique varieties that way.  

Some places we have bought seed potatoes over the years include Seeds Now, Peaceful Valley, Territorial Seed, Johnny’s, Irish Eyes, and High Mowing. We also sometimes see them at our local garden center or nursery!

NOTE: Most places will sell out of seed potatoes by spring! It is important to order your potatoes in the winter to ensure you get some, or you may be left with slim pickings.

There are dozens, even hundreds, of different potato varieties to choose from! Spuds can vary in size, shape, color, texture, flavor,  best use, and time to harvest. Read through the seed potato descriptions to see which variety you may like best! They’ll usually say if that variety is known to be more mealy or crisp, juicy or dry, and which ones are better for storing, mashing, frying, or baking. Speaking of different types…

What are Early, Late, and Mid-Season Potatoes?

When you’re potato seed shopping, you’ll likely see one of these three designations with each variety. Which variety of potato should I choose? To help you decide, here is a brief breakdown of their differences:

Early season potatoes, or “new potatoes” reach maturity within only 75 to 90 days. These could be ready to harvest in early summer, depending on when you planted them. If you are in a climate with very hot summers, choosing early season varieties may be best to beat the heat! Potatoes don’t love temperatures over 80 degrees. Alternately, if you’re shooting to plant a round of potatoes in late summer for a fall harvest, an early-season type may be ready for harvest before the first frost hits.

Early potatoes are least likely get blight, as they’re usually harvested before disease can take hold. However, they don’t last as long in storage. A couple popular early potatoes include Caribe and Norland, but there are many!

Mid-season potatoes, also referred to as “second early” are just a tad longer than earliest types. These ones will be ready to harvest in about 95 to 110 days. Yukon Gold is a widely popular and delicious mid-season potato that grows well in warm climates.

Late-season potatoes, also called “main crop potatoes” are generally finished growing and ready to harvest within 120-135 days, closer to the middle or end of summer. While they take longer to grow, the late-season type are known to last longer in storage as well.  These are said to be best for baking, mashing, and roasting. The earlier varieties are more crisp and tender for pan-frying. Kennebec and Butte are well-known late-season varieties.

If you’re like us and plan to grow several varieties, check out this 4-pack of 20-gallon grow bags! Amazon also has a 5-pack of 15-gallon bags that have handles, which makes moving them around much easier. These bags come in handy for many more crops than just potatoes! We use them for peppers, tomatoes, and others too.

Grocery Store “Seed”

If you do opt to try to grow from store-bought spuds, here are a few tips: One, most definitely choose organic. Inorganic produce can be treated with chemicals that intentionally inhibit sprouting. That will just thwart your efforts. I would also suggest buying your potatoes well in advance (like months) before you plan to plant them. This will give them plenty of time to soften up and sprout for you, also referred to as “chitting”.

Chit or Get off the Pot

Chitting is the process of encouraging your potatoes to sprout in anticipation for planting. By sprouting them in advance, it gives the potatoes a head start and will result in a more robust harvest!

The chitting process can take 4 to 6 weeks. To chit your potatoes, you may need to first put them in a warm, dark location for a week or two. Around 70 degrees is a good target. This helps them break dormancy – waking them up to allow for sprouting. (This applies to potatoes that are not already starting to sprout.  If they are, skip to the following step.) After that, move them into a slightly cooler area with bright ambient light. Not necessarily in a bright window, but somewhere with exposure to decent light. We set ours on a shelf in a spare room across from a large window.

Five paper bags are flattened on top of a large tray. On top of each paper bag is a little pile of different type of seed potato. They are all sprouting. Some are small and more green, some are large a purple.
Our seed potatoes for 2019: Magic Molly, German Butterball, Huckleberry Gold, and Jelly. I already planted the Red Thumb fingerlings and forgot to take a photo first! They’re the ones I planted during the demo video you’ll find at the end of this post.

When you move them out into the light, take a look at each spud. Determine which side of the potato has the most eyes. The eyes are the little indentation or nubs along the otherwise smooth potato skin. Those eyes are where potential sprouts will emerge from! The portion of the potato with the most concentrated number of eyes is called the “rose end”. Place the seed potato in a position with the rose end facing up, exposed to light. With this treatment, they should begin to sprout shortly.

Again, if you buy seed potatoes from an online seed company, they very well may come sprouted and ready to go!

Cutting seed to create more

Seed potatoes can be cut into smaller portions to create more seed! This isn’t necessary when the seeds are already fairly small, or if you have more than enough on hand already. However, if your seed potatoes are very large and you would like to get even more seed pieces, you might be able to cut them. I say “might” because this depends on the seed and how many eyes it has.

When cutting up a seed potato, ensure that each new piece will still have at least one or two promising eyes once divided. Using a clean knife, cut the larger seed potato in half (or more, depending on size and eyes). It is important that you do this at least several days prior to planting outside! A week or more is even better. The fresh cut sides need time to dry and scab over before being planted. If they’re planted when wet and exposed, you run a great risk of having them rot in the ground!

This is where I could have cut this seed in half – and let it properly dry and scab over for a few days before planting? Like my knife? It’s definitely CutCo.

Planting Timing

Once your potatoes are nice and chitty, they can be planted outside once the soil temperatures have reached at least 40 degrees Fahrenheit. Another way to determine timing is based on the last frost date for your growing zone. For potatoes, they can be put out as early as two to four weeks before your last frost date. I say “as early as” because you don’t necessarily have to start them then.

In our moderate climate, we are able to start potatoes at various times throughout the year! However, if you live in a place with very hot summers, you will want to start them as early as possible to avoid the hottest part of the summer. Potatoes don’t love extreme heat. We’ll talk more about that soon.

If you aren’t sure about your zone, frost dates, and planting times, refer to the Homestead and Chill planting calendar! If you haven’t gotten yours yet, you can get it immediately via email by subscribing.

Potato Soil Preferences

Rich and Fluffy

The ideal soil for growing potatoes will be rich, full of organic matter, and fluffy. We always add some compost and worm castings in with our potato soil! Avoid high nitrogen fertilizers. Your potatoes will grow large greens but smaller tubers with too much nitrogen present. To help keep the soil from becoming compact, which is not something potatoes enjoy, straw is often used when growing potatoes – to create extra fluff. We’ll talk more about straw below, in the “Care While Growing” section.


Did you know that potatoes love acidic soil? Yep! Most potting soil or garden soil is closer to neutral or just very slightly acidic, with a pH around 6.5 to 7. In contrast, potatoes prefer a pH range of 4.8 to 5.5 to thrive. To accomplish this, you can amend your target soil with horticulture sulfur. Keep in mind that sulfur is generally slow-release, thus, it can take months for the soil to adjust its pH. Using this technique, planning in advance is required!

A few years ago we stumbled across an organic bagged “Acid Planting Mix” soil by G&B Organics, and have been using it to grow potatoes ever since. The pH is already adjusted for us! Furthermore, it is a perfect texture, and has a ton of other great amendments added too – like worm castings and kelp meal.

A bag of soil that says "Acid Planting Mix" is leaned up on a garden cart, that has two large tan fabric grow bags on the top of it. Those bags are being filled with that soil soon. The cart is positioned on a patio area with plants in the background. A hand reaches into the soil and shows it has a fluffy texture.

The fact that potatoes grow well in acidified soil is the one of the biggest reasons we do not grow them in our raised beds. Rather than doing a bunch of pH adjustments to the beds, we’d rather give the spuds their own designated happy place. We use the same soil and treatment for our acid-loving blueberry bushes, who are grown in their own wine barrels.

Unfortunately, I believe G&B Organics is only available on the West Coast. We find it at our local Farm Supply. If your local garden center carries G&B soils but not this mix in particular, ask and see if they can order it in for you! Ours does, at no additional cost. For folks who live elsewhere, keep your eyes out for their “Shade Planting Mix” – which is the equivalent product in their Kellogg Organics line. Your local Home Depot or Lowe’s probably carries it.

If you look around and can’t find an acidic soil, don’t stress over it. Plant them anyways! Acidic soil is said to help them grow better and stronger (and be more disease resistant) but I am sure people grow them okay in regular soil too.


Potatoes like to be evenly and consistently moist, but never soggy. When overwatered or grown in heavy soil, they could rot! Therefore, the soil you use should be able to drain well, but also have good moisture retention. It’s all about balance. This is one of the many reasons we prefer using fabric grow bags! They’re easy to assess and control moisture, and do not become water-logged easily.  If you are using a more solid container, ensure it has plenty of drainage holes!

Planting Your Seed Potatoes

Fill your chosen container about one-third to half-full with the perfect acidified, rich, fluffy soil and compost. The amount will vary depending on the size and depth of your chosen container. The goal is to have enough soil to allow several inches of soil (at least 4-5”) below the seed potatoes, a few inches on top, plus some room to spare to add more soil later as they grow.

Bury sprouted seed potatoes about 3 inches deep in the soil, and about 4 to 5 inches a part. Note that I will put more smaller sized seed potatoes in a bag, and far fewer if they are large. Water thoroughly.

Four images of planting sprouted seed potatoes in grow bags. In one bag, there are more potatoes because they were smaller. About 10 small purple potatoes. In the same size bag, only 5 large sprouted are shown, giving them at lest 4 or 5 inches apart. They're not yet covered by soil, just sitting on top, waiting to be buried. Another photo shown a hand pushing them down in the soil, burying them about 3 inches deep.
Planting seed potatoes, about three inches deep in the soil and 4 or 5 inches apart. Note that I could only fit 5 very large seed potatoes in the same size 20-gallon grow bag, but could fit a few more smaller ones.

Ideal Growing Conditions

Place your potato container in a location that receives full sun. The ideal temperature range to grow potatoes is 50-80°F. If you live in a climate with very hot summers, consider a location with a little late afternoon shade. Also avoid the hottest spots of your garden, like near a south-facing wall or other source of radiant heat.  If you get them started early enough in the season, or grow them in fall instead, this may not be a concern!

Care While Growing


Provide consistent, even, deep moisture. Don’t drown them every day, but don’t let them fully dry out between watering either!

Topping off the container

The foliage portion of potato plants will begin to grow and emerge above the soil line. After they reach at least 6” tall, bury the majority of the exposed green stems with more soil and compost, but still leave a couple inches of the greens exposed on top. Why are we burying the stems as they grow? Because more potato tubers will grow off of the stem that’s buried! Repeat this process over the following several weeks as the foliage continues to grow taller, until your container is full and you cannot add more soil.

When topping off potatoes, we usually add more of the acid planting soil mixed with compost. Sometimes, we add a light layer of straw too. Straw helps keep everything nice and fluffy, the way potatoes like it! If you live an area with rainy summers, I definitely suggest adding a couple “lasagna layers” of straw in with your soil and/or compost to help promote drainage.

You may be able to tell in the photos that we usually start with our grow bags sides rolled down. This way, as the greens first sprout up while the soil level is still low in the bag, the greens still get as much sun as possible. As they grow and we add more soil, compost and straw, we can unroll the sides of the bags as needed – until the whole thing is full to the brim.

Two photos. On the left, a tiny purple green potato sprout is pushing up through straw. On the right, large leafy potato greens are now emerged, in three different fabric grow bags.
Left: the first spud sprout has emerged!
Right: After a good topping off of compost, soil, and straw. The greens were almost a foot tall and exposed prior.


Potatoes are modestly heavy feeders. Don’t skimp on the compost! We also water them once per month with a dilute seaweed extract, or aerated compost tea from our worm bin. We don’t use all that much “fertilizer” to grow potatoes. As I mentioned, a high-nitrogen fertilizer isn’t recommended for potatoes. However, we may add in a sprinkle of something more mild like kelp meal once or twice while they’re growing.

Harvest Time

After a few months of good growth, the potato greens will start to turn yellow and then brown, slowly dying back.  This is a sign that it is close to harvest time! During the time the greens are withering away, the potato tubers are drawing in the last bits of energy and nutrition from them. Meaning, even though the greens look like crap, the potatoes are still growing. You can cut back water at this time, but wait to harvest until it has been at least 2 weeks after the greens have completely died back.

Harvest time. See how died back the greens are? A month ago, they were full of nearly 2 foot tall vibrant greens. We could have even waited another couple weeks on the 2nd and 5th bag in the line, but the greens were died back enough to go ahead and harvest with the others that were ready.

Potatoes just may be one of my very favorite things to harvest! An additional bonus to growing in containers is that you can just dump them over and start hunting around for spuds! If they’re light enough, that is. We are able to empty our fabric grow bags into a wheelbarrow, making it more comfortable on our backs (hot damn I sound old…) and also easier to dump the soil back into the bags afterwards. This method also reduces accidentally damaging the potatoes, compared to digging them up with a shovel or pitchfork.

A little clip from one of our grow bag – wheelbarrow potato harvests! It’s like digging for treasure!

Storing Potatoes

To be honest, our potatoes never last long enough to worry about long-term storage. We pop them in a paper bag and store them in a cool dark place, like a spare bedroom closet. They always hold up for a couple months without getting soft. By that time, we have usually eaten them all. However, if you kick butt at growing potatoes and have way too many to store in the fridge at once, check out these tips on curing and longer-term storage from Gardeners Supply!

After all that, the best part is yet to come: eating and enjoying the best potatoes you have ever tasted! If you have never had the pleasure of tasting homegrown potatoes, I am super excited for you!

Are you ready to go grow some spuds?

What is your favorite way to prepare potatoes? I am a sucker for pan-fried, or mashed – with garden chives on top. One of our favorite potato recipes is this Roasted Two-Bite Garlic & Herb Smashed Potatoes, perfect for the smaller-than-average homegrown spuds!

  • Marta

    Hello! Thanks so much for this article! I wondered if you could share how deep the soil should be when you plant the seed potatoes? I see you hill them up several times after so I’m curious how deep they need to be to begin with. Thanks!

    • DeannaCat

      Hi Marta – The goal is to have about 4-5″ of soil below the seed potatoes and then a couple inches on top at first. Happy planting!

  • Allison

    Here in Northern NV, I just planted organic grocery store potatoes that were getting soft and sprouting. I have never tried this, but your article is so informative I feel confident to try it this summer. Thank you for such a well written guide!

  • beebarbles (Barb)

    Deanna, your articles are so good. So informative. So thorough. My organic potatoes from the grocery store are scabbing over now and I feel like you given me all the tools to be successful, so I just wanted to say thank you so much! Barb

  • Katie


    I had to come back to this post because… ugh, I forgot to write down when we planted our spuds. But you cover every single thing, so we’ll be waiting for the tall fluffy greens to die back, get brown and then wait another couple of weeks before we harvest. Thank you so much for sharing your knowledge, Deanna! We’re in San Diego in an HOA rental so it’s been challenging to find room for growing anything. They took my worm bin a couple of weeks ago while I was out of town… =/ I’m hoping after quarantine to setup a meeting and talk about a garden for the property, there’s plenty of space and your killing grass to make room for food will hopefully be a selling point!


  • Brittany Gierke

    Reading through this because it’s almost potato time here in southern Oregon! Waiting on some of my seed potatoes to chit? (Was that the right word lol) I have to say, your tutorial was WAY more thorough than anything I’ve read or been told by our local grow store. Can’t wait for my first home grown potatoes. Some of our friends use potatoes in the beds they struggle with symphylans!

  • Lillian

    So our potato planting season in Central Florida is sort of the December – February time frame, but no one has seed potatoes available to ship until March and April. I’m wondering, if I order them for the spring, is there anyway to maybe keep them frozen or stored somehow so I can plant them in the winter?

  • Leslie Sugiura

    Hi there! Is there a way to save some of the potatoes grown this summer as seedling potatoes for next year or should I just start all over again? Thank you!

    • DeannaCat

      Hi Leslie. It depends on how long it will be from the time you harvest until you plant again. You could save some in a cool dark location to prevent sprouting now, then bring them out to start the chitting process a month or two before you want to plant again! However, you can’t guarantee they’ll last that long. Depending on the variety, storage conditions… Honestly, we usually eat our entire harvest and then get more seed – mostly because we don’t have enough space to grow A TON of tates, so we want to eat our modest harvest! If we had extras to spare, we’d probably save more seed. I hope that helps!

  • Anne Dottai

    I was sooo excited to harvest my potatoes today, but thanks to your informative article, I need to wait at least one more week. Should I just leave all the wilted “greens” or cut them back? Thanks!

    • DeannaCat

      Nope, don’t cut them! The spuds are still drawing energy and nutrition from the greens, and allowing them to yellow/brown and die back is part of their curing process. I know you’re excited, but patience is worth it here Mom 🙂

  • Jessica

    Love growing potatoes! They are so easy and my kids freak out when it’s time to harvest them, or as we call it “Going on a Potato Treasure Hunt!” 🙂 One question, this year I have been so busy and my plants have been needing to be hilled for several weeks. Is there a point where they’ve gone too long without being hilled and they won’t produce more tubers?

    • DeannaCat

      As long as they still have green growth above ground, you can continue to hill! If the greens have already started to die back, it may be too late or not worth it. Have fun treasure hunting! 🙂

    • Kirsty

      Thanks for this detailed article! I would love to hear your advice on what you do with the compost after the potatoes have sucked the life out of it. How do you incorporate it into your garden the following year? Thanks!

      • DeannaCat

        We save the soil and use it the following crop or season, we just add more compost and amend it a bit with kelp, alfalfa, and neem seed meal.

  • Lisa

    Hi Deanna! Thanks for such an awesome and thorough tutorial. My question- do you think it ok to put two different varieties in one container or should they be put in separate containers? I just bought “all red” and “vermillion fingerling” varieties from Seeds Now. One is a mid-season variety and the other is unspecified.

    Second question- in SoCal (Los Angeles), if planting now, would the mid-season variety be the one to plant? Probably should have asked this question before I bought the potatoes!

    Thank you for your advice!!

    • DeannaCat

      You’ll be fine in SoCal with pretty much any type now, since you don’t have any sort of impending winter frost to beat. You can put them in the same container, though we typically keep them separate in case they finish at different times – and you want to stop watering much after the greens die back. Let me know how it goes! Good luck 🙂
