Growing Potatoes in Bags and Containers

If you only have a small garden, like myself, you can still plant and enjoy a good potato crop. I show you each stage of planting, growing and harvesting potatoes. Step by step instructions with videos and photos. There are three distinct times to plant out your seed potatoes. I have outlined each one below.

Tips for Growing Early Seed Potatoes

Preparation of the seed potatoes a few weeks before you plant them out is essential for a good crop. You can plant early seed potatoes in containers in late February to March. Keep the tender shoots protected from frost by covering the soil with straw or a plastic sheet. These are the potato variety that I planted last year and I got a great crop from them.

Early potatoes grow quickly and you can harvest a nice crop in about eight weeks.
You will know it is nearly time to pick them when the flowers begin to bloom. Wait a couple of weeks and then lift the plants up out of the dirt to expose the new potatoes. Only harvest what you are going to eat for the next couple of days. The remainder left in the containers will still continue to grow.

Second Early Seed Potatoes

These can be planted from March to April. They will take more time to grow. They will be ready to be harvested in about fourteen to sixteen weeks. You will get a better yield from this crop.

Main Crop Seed Potatoes

You can plant these in April or early May. These will take the longest to grow. They take about eighteen to twenty weeks until they can be harvested. The main crop yields the largest amount of potatoes.

What Size Containers Can I Use?

The container should be at least fifteen to twenty inches in depth and a bit wider at least in width. A large bag will be these measurements in depth so the wider the bag, the more you can plant.

You have a choice of specially-made barrels, large pots, buckets, or even large supermarket bags. If this is your first time planting potatoes, I would recommend you find something already in your garden that you can use for free.

Preparing the Seed Potatoes

When you buy seed potatoes, you will notice they have very small sprouts or eyes coming out of them. You want to encourage growth of these shoots before they are planted.

This Process Is Called Chitting

  1. Put them, with the eyes facing up, onto a plate or flat surface.
  2. Place them in a sunny, light, and warm place. If planting in February or March this might be indoors.
  3. It should take about four to six days for the shoots to grow.
  4. Use the best to plant out, those with at least two to three sprouts on them. This gives them a head start in the growing process once they are planted outside.

How to Look After Potato Plants as They Grow

For whatever container you are using, carry out the same steps:

  1. Make sure the containers you are using have good drainage.
  2. Add compost to fill a third of the container.
  3. How many potatoes you plant in each container depends on how large it is. Remember, you need to leave room for them to grow.
  4. Place the seed potato with the shoots facing up.
  5. Cover until only the shoots are above the compost.
  6. Water the pot to settle the plant.
  7. When the shoots are about ten inches high, add more compost.
  8. When they grow bigger, do the same again until there is no more room.
  9. Water when needed.

When is it Time to Harvest Potatoes?

You will know the potatoes are growing successfully when the flowers have been blooming for a couple of weeks. Continue to add soil to the bag and to water.them.

After another few weeks you will see that the flowers die off. Wait until the leaves start to wither as well. You will know the potatoes are ready to harvest when all the leaves have died.

Why You Should Buy Seed Potatoes

I did not want to spend money buying seed potatoes, so I took some from the bag I bought in the supermarket and used them. This is a common mistake a lot of people make.

My crop was not too bad as you can see from the photos, but there were not many to each bucket. It would have been more productive if I had bought the seed potatoes.

Questions & Answers

Question: I have grown some potatoes from seed in bags and harvested them. However, I cannot tell at all which were the seed potatoes and which are the potatoes that have grown. I'm worried because all I read is that you should not eat seed potatoes. What can I do?

Answer: All of the potatoes that you harvest are safe to eat. The seed potato has dissolved into the soil by the time you pick the newly grown potatoes.

Hello Ella, thanks for dropping by.

Nearly time to plant the seed potatoes. I am looking forward to another spring so I can spend lots of time in my vegetable garden.

Ella Wilson on February 01, 2018:

Hi, LM! I have seen lots of blog post about growing potatoes in bags and your post is the one that got my attention. I love how you wrote the step by step process! Thanks for sharing this post!

L M Reid (author) from Ireland on April 06, 2016:

Hello lrdl3535, Yes the small potatoes can be eaten and are delicious. The potatoes will become green if left uncovered by the soil which allows the light to get at them. You are correct green potatoes should never be eaten.

Richard Lindsay from California on April 01, 2016:

Hi, Great post on potatoes with lots of good information. But I have a question about digging up the potatoes. If you dig up the potatoes when they are small can you eat them? When do they become green and not edible?

L M Reid (author) from Ireland on April 09, 2014:

My potatoes I planted this year are growing nicely. Thank you Maren for taking the time to leave a comment

Maren Elizabeth Morgan from Pennsylvania on April 03, 2014:

Great info!

L M Reid (author) from Ireland on February 28, 2014:

Hello Phyllis. lol you will have an array of colour on your patio and be able to eat it. My seed potatoes are already on the table chitting so yes it is a good time to order now.

The peppers grow just fine when you take a few seeds from any you have bought to eat in the grocery store. So there is no need to buy seeds specially for that. I will be writing an article about my peppers soon so you will be able to see how successful they grew from taking seeds this way.

Good luck and here's to a bumper crop on your patio

Phyllis Doyle Burns from High desert of Nevada. on February 28, 2014:

Greetings again, viking. Wow ! you are filling up my patio right quick and nicely. No, I have not tried peppers and I love them. So - now I will have potatoes, tomatoes, and peppers -- plus my herbs (rosemary, sage, basil and thyme). lol this is going to be a fun and productive summer for me thanks to you. I am anxious to get started now. I will check out your hub again, you did have an Amazon link for the seed potatoes, right? I had better order them very soon.

L M Reid (author) from Ireland on February 28, 2014:

Hello Phyllis it sounds like you will have great growing conditions for tomatoes alright. Have you ever tried growing peppers on your patio, the sun will help them along nicely

Phyllis Doyle Burns from High desert of Nevada. on February 26, 2014:

Yes, definitely tomatoes. I get about 5 hours of full sun, so will give it a try. Thanks.

L M Reid (author) from Ireland on February 26, 2014:

Glad to be of some help syzgyastro. Yes I too made a mistake last year by planting out potatoes I had bought from a supermarket and not buying Seed Potatoes. They did produce a decent crop but not as much as I am hoping to get this year.

Good luck with the growing of your Yams and Sweet Potatoes this year too.

L M Reid (author) from Ireland on February 26, 2014:

Hello Phyllis I am delighted I have encouraged you to start growing vegetables again. If your patio gets lots of sun you could buy a couple of tomato plants and grow them too.

L M Reid (author) from Ireland on February 26, 2014:

Hello lmoyer02 Yes I got the idea of adding some potato recipes to this article by reading what constitutes a Stella Hub in the Hubpages learning Centre.

I have written an article about various ways to cook and eat potatoes at this link. The perfect Baked Potato recipe is there too.

William J. Prest from Vancouver, Canada on February 25, 2014:

Thanks for all you input. I will be planting some this year. I now know what went wrong in some previous years and will do things as suggested. I will also be experimenting with yams and sweet potatoes which are an unknown for me.

Phyllis Doyle Burns from High desert of Nevada. on February 25, 2014:

This is a really great and interesting hub. I have just a very small patio, but am going to try growing potatoes this year in a container. It has been a long time since I grew potatoes and that was in a large garden. Thanks for all the tips and instructions.

Leon Moyer on February 25, 2014:

Well written and helpful article. I like how you added potato recipes into the same hub describing how to grow them. Have any tips on making the perfect baked potato?
