Choosing Winter Sowing Containers

Winter sowing is a technique that is used to start seeds outside during the winter. The seeds are sown in miniature greenhouses that you make yourself using recycled plastic containers. There are many different types of containers you could use for winter sowing, and it’s fun to experiment.

Rules for choosing winter sowing containers

Winter sowing containers can be made out of items you throw out every day; containers like milk jugs, 2 liter bottles, restaurant/deli/bakery food containers, ice cream buckets… etc. There’s really no limit to the type and shape of containers you can use for winter sowing, but there are a few important rules to follow when looking for winter sowing containers…

  • Winter sowing containers should be made out of plastic (you could use containers where the bottom is made of Styrofoam or foil too, as long as you can poke holes in them)
  • The lid on a winter sowing container should let light through (i.e.: the container should not be completely opaque)
  • Winter sowing containers need to be deep enough to hold 2-3 inches of soil
  • Your winter sowing containers should be tall enough to accommodate the height of the seedlings as they grow (allow a few inches of headspace)

My top picks for winter sowing containers

  • Old food storage containers (look for these in the free bin at garage sales)
  • Disposable food storage containers (I like the larger 64 oz size, or the 48 oz size for shorter seedlings)
  • Ice cream buckets
  • Food take out containers (these are some of my favorites)
  • Food containers from the grocery store deli (I like these)
  • Containers from bakery goods

Winter Sowing Containers

When it comes to choosing winter sowing containers, it boils down to what you prefer and what types of containers are available to you. The types of containers I prefer to use for winter sowing are ones with lids that are easy to take off and put back on, like ice cream buckets and food containers. Milk jugs also work very well for winter sowing, and are readily available.

I especially like winter sowing containers that can withstand the heat of the dishwasher without melting. This makes the task of cleaning hundreds of winter sowing containers much easier. I’ve noticed that if my winter sowing containers can survive in the dishwasher, they usually last longer so I can use for more than one year.

Some winter sowing containers will hold up to the elements better than others. I have had containers that start to disintegrate after only a few months of being outside. I’ve had others that hold up very well and I can use them for multiple years.

Making Modifications to Winter Sowing Containers

What if you have a great winter sowing container, but it doesn’t have a lid… no problem. You can make some easy modifications to turn it into the perfect container for winter sowing seeds.

Simply cover the container with a plastic bag and secure it at the bottom with a twist tie, then poke a few holes in the plastic to allow moisture in and to vent the container. Make sure to pull the plastic as tight as you can so it won’t blow away. If the container will fit into a one gallon zipper bag, you can put it in and zip it up… but make sure that you poke holes in both the top and the bottom of the bag, as well as in the bottom of the winter sowing container.

One thing to note is that some “plastic” take out containers are now made out of corn, which is great for the environment… but not great for winter sowing seeds unfortunately (and these will disintegrate in the dishwasher). It’s best to experiment with containers and see what you like. Sometimes you have to take what you can get, and then you’ll know what winter sowing containers to choose for next year.

    This is a very cool idea, I attempted an outdoor winter seeding of crocosmia lucifer and seeded in october. The problem was small sprouts appeared in mid december and were nuked by the frost. Who knows what might pop come spring but putting a lid on things might give them that extra warmth to survive. Great post!

    Hi Nat! It is pretty cool isn't it. I was very excited when I discovered this technique too, and it has become very popular over the last few years. I was nervous to try it out, but it's so much easier than starting seeds indoors. I hope you will try it and share your progress with me. I will be starting my winter sowing sometime in the next few weeks and sharing my progress.

    Hi Amy
    I have been putting aside some old containers. I can't wait to try this out. Do I use regular gardening soil or should I use the seed starting soil?

    Hello Anonymous! It's funny, someone else just asked me the same question yesterday. I use the same type of potting soil in my winter sowing containers that I use when starting seeds indoors. I buy the seed starting soil mix that is specifically made for starting seeds. It's a little more expensive than other soil mixes. You could probably find a recipe online to mix your own seed

    Thanks for the update. Before I submitted my post it said "Tara said…" I am not sure why it changed to anonymous. Love your blog Amy and I reference quite often. I will be trying to do as you do this year so I am not so far behind and still waiting for veggies in the fall. I am pretty excited to try out winter sowing. I have some seeds that I bought last summer, but I am going

    You say you start sowing in February. This winter seems to be exceptionally cold – will you still be starting them this month? Also, I don't have a deck or patio – but I would put the containers on my outside table for the morning sun – or is it okay to put them on a sheet of cardboard or some such thing directly on the snow?

    @Tara – howdy neighbor! Glad to hear you're going to give winter sowing a try this year. Can't wait to hear all about it! I usually buy my seeds at Bachmans… but this time of year, you can pretty much find them at all the big box stores too. There are tons of companies that sell them online if you want to price compare. Shop now for the best selection.

    Hi SecondhandKris – Yes

    Hello! Love the information! I have been researching winter sowing on and off over the last couple of weeks and just had a quick question about containers. I like the idea of using containers that you can just stick directly into the ground (peat pots, TP rolls, egg shells etc.) – I know two of the "rules" of winter sowing is to having a container that is deep enough for the 2-3"

    • says

      Hi Allison – I have heard of people using their normal winter sowing containers with the TP rolls/peat pots inside. They fill in between the rolls/pots with soil to help retain moisture. The biggest concern with using this plantable materials is that they can act as a wick and draw moisture out of the soil faster than normal. I think your method sounds like it should work, but keep a close eye on

    I am planning to try out winter sowing this winter. I never tried it out before. Your post was very helpful for me to get to know some useful tips on it. Hope, i succeed in it with your useful tips.
