Using perennials—and even small shrubs—in containers has become more and more common as gardens shrink and breeders develop compact varieties. Hostas are among those perennials that do very well growing in the confines of containers. They come in thousands of cultivars and they are easy to care for, making them the perfect plant for busy or distracted gardeners.

Plant ’em Tight

First, most experts recommend choosing a pot that is somewhat on the small size for the mature size of the plant. When you plant the hosta in the container, you want less than 3 inches of space between the roots and the edge of the container. A small pot may require more frequent waterings, but it’s best for the overall health of the plant.

Like all container plantings, make sure you have good drainage. The water should easily flow out of the bottom of the pot after a thorough soaking. Get good drainage by drilling a few extra holes in the pot. It’s better to thoroughly water the container less frequently than to give the plant just a little water every day. In warm or especially dry weather, however, you likely will need to water your container every day or two, no matter what. One nice thing about hostas is that when they are dry they will wilt a bit, but they won’t dry up and die right away. If your hostas are wilting, they are asking for a drink. Your bigger risk with hostas is watering too often, causing crown rot.

Set the container outside in a part-sun or shady spot. While some hostas can take deep shade, most prefer dappled shade or a bit of morning sun.

What About Winter?

You can keep your hostas in containers from year to year, but it’s not as easy as overwintering the ones in the garden itself. In fact, some folks will plant their container hostas in the ground for the winter.  Other gardeners bury their pots outside, so that the roots are underground, just as a garden hosta would be. Another option is to more the pots to a somewhat protected area (near the side of the house, etc.) and cover the pots with a lot of mulch. That may be tricky, though, if we have a very harsh winter. A fourth option is to bring the pots into an unheated garage or shed after they have gone dormant. The plants will require water a couple of times during the winter, however, to keep the soil from wicking water out of the dormant roots. Whatever you do, do not try to over-winter hostas as houseplants. They need a cold, dormant period.

Do you grow perennials in containers? Which ones?

    I am a big fan of planting perennials in containers! My farm is in zone 5 therefore winters here are cold and snowy. I’ve found that most perennials overwinter great in containers if they are planted early in the year so that they have an established root system going into winter. A few of my favorites are: Rudbeckia Herbstonne, all Heucheras especially the trailing varieties, Hostas, and Nepeta (for the hummingbirds). Great post – thanks you, lots of good information:)

    I enjoyed planting and always wanted to learn about it, the information in this article really useful for my project, thank you for sharing

    Thank you for this! I have a hosta in the type of container that you recommended. This will be its second winter. Last year I did bring it into the house (but I have the heat on low or not at all when I’m not home, usually). However, this year, as per your advice, I will put it in the shed. Thanks again!

    I have planted almost all of my hostas in pots. They do great and come back each year healther and a little bigger.

      Hi Charlotte, how often do you water. Do you take your Hostas to the garage.

        Kimberly I have HUGE hostas in pots. I have done this for years! I am Rhode Island zone 5b/6 and they come back each year. I just leave them in their spot in the garden as they are too huge to move. I don’t wrap them, water them, or do anything. I just forget about them like all the other gardens all winter and they are always perfect

          This is awesome to hear! I’m in zone 5 (Ontario) and I have always wanted to grow hostas in pots, but I’ve been too afraid that the maintenance for Winter would be too much. I think I’m going to try to plant a few and do what you do!

          @ Jody : Thank you very much for your useful information regarding taking care of Hosta in containers. I ” discovered ” these
          perennials this year and I am charmed by them . I bought a couple of varieties of Hosta plants and Heucherella plants as well
          and I placed all of them in containers. I LOVE them ! They truly give me a lot of joy.

    I have just purchased some hostas for the side of my house. My house has pea gravel at the side because of a leak in my basement and it was filled in with pea gravel about 10 feet deep all along the side of the house.
    Can I plant these hostas in their pots that I purchased them in ?

    • Mary Lahr Schier on June 5, 2019 at 4:55 pm

      You could, though a larger pot might be better.

    • K Gemmill on July 17, 2019 at 2:18 pm

      I had to take my hosta’s out of the ground because slugs were relentless. Tried everything to keep them slugs away. Not sure but wondered if ground area was too damp or shaded so perfect for slugs. Now need help figuring out what to plant in that area. I appreciate your information. I now have them in pots so hopefully they are safe and stay healthy . Thank You

      • Mary Lahr Schier on July 19, 2019 at 3:10 pm

        It’s been a bad year for slugs in Minnesota! Too much rain.

      • Dan on November 6, 2019 at 7:53 pm

        Crushed eggshells are the ticket for deterring slugs and snails. I start scattering the shells before the plant sprouts in the spring to ensure the ground underneath all the foliage is covered. I then continue to add shells around the plant as it grows. The only real way snails or slugs can get into the plant surrounded by the crushed shells is from above, so be diligent about not growing your hostas near taller plant where snali/slugs could migrate from their host plant to your hosta. Works for me. Good Luck!

    I noticed how well my hostas grow in pots but not in the ground. Will they be healthier, bigger if I sink the pots in the ground to plant ?

  7. Terry Vance Sheldon on October 16, 2019 at 1:10 am

    Do you cut back the Hostas in the fall if they are in pots?

    • Mary Lahr Schier on October 16, 2019 at 1:31 am

      It’s optional. I usually cut mine because they get messy in the spring. Be sure to give the pots a little protection for winter.

  8. Bea on April 19, 2020 at 1:06 pm

    I plant my hostas in containers. However, I live in Wisconsin and when can I bring those out for spring? They are starting to come up, I have them in my garage. I don’t want to bring them out to early. Please help

    • Mary Lahr Schier on April 19, 2020 at 3:16 pm

      I’m not sure where in Wisconsin you live, but if you are in zone4 or 5, you should be able to bring them out now. If it gets super cold overnight, you could throw a blanket over them. Hostas are pretty tough.

  9. Karla on June 18, 2020 at 3:01 am

    Do hostas in pots require repotting at some point? I have a huge one in a large pot and I feel like it’s out growing the pot!! Thank you!!

    • Mary Lahr Schier on June 18, 2020 at 2:24 pm

      Yes, anything grown in a pot may require repotting at some point. You can go to a container one size up or plant it in the ground.
