Spinach is one of my favourite greens to grow in the garden, for so many reasons. It is the first crop to plant and to harvest in spring, it stays alive over the winter, and it needs no extra space in the garden.
In this post we share with you a video that I made in the course of a year. There are many clips of the planting, growing, and harvesting of overwintering spinach in cold climate. I started the first video last year in October, so you will see that there are different plant locations.
I have been growing overwintering spinach in cold climate for several years now and know it works. We actually discovered this method accidentally when one spring some of last year’s spinach started to grow new leaves. I was so amazed! I could not believe spinach would survive these cold temperatures, but it does.
Then I started planting spinach whenever there was space available for a fall harvest. I would harvest the spinach before the winter by cutting the tops and then leave the roots in the ground. I was happy to see that many survived the winter and continued to grow in spring.
These greens provided us with early greens and protected the soil from weed overgrowth long before we could get to the garden. This is another great advantage of growing overwintering spinach. Then we actually started planting spinach in August with an early spring crop in mind.
The process is very simple.
- Plant spinach in late summer whenever space becomes available.
- Let the spinach plant mature to at about 2 inches before cold and frost come.
- Let the spinach plant die back in the winter without disturbing the plant (just leave it alone).
- You do not have to cover the plant even in zone 3 (temperature drops to -40), but you can add a layer of mulch if you haven’t yet.
- Let the spinach plant regrow in spring.
- Harvest and enjoy the earliest, and probably best, spinach you ever had.

If your climate allows growing more than just spinach, here are some inspiring books for winter growing, there is a lot possible:

I live in zone 3 (Manitoba), and I have some empty space and a fresh package of spinach seeds. I’m going to try this! I’ll plant it in the same area as my garlic. Do you know if there are any other things you can plant like this? I’ve had other plants survive the winter if there’s a deep snow cover – even had several small (missed, and forgotten, alas) potatoes that survived the winter and sprouted themselves. Thank you for the inspiration!
Good luck Heather with your trial. I am very curious to hear how it will work for you. The difference between our and your weather is the long stretch of -40. We do not get that. It is usually just a touch down. But with a good snow cover it still should work. I don’t know of any other annual plant that would do that except garlic and spinach. Happy gardening!
Swiss Chard will overwinter too. It did it in my garden and like you, Anna it was an accidental surprise!
It is always worth trying, I have Swiss chard plants still in the garden, leaving them to see what happens. Thank you for sharing.
Thank you so much for the awesome information! I have an unrelated question but would like to know what your practice is, How do you deal with aphids on your vegetables? Just went to check mine and found aphids all over my Chinese greens and even my beet greens!
In the outside garden, we mostly do nothing. Nature usually balances itself out. If we find that a plant needs some help. a good shower with a hose is the first thing that we do. Also be aware that if there are many ants around, they protect the aphids. You can relocate the ants by relocating the nest or spraying some cinnamon, which ants don’t like. By using pesticides in the garden, every insect gets killed. It is hard to establish the balance again.
I`m gonna try leaving my swiss chard in my North West Ontario Garden. I Tried bringing in a couple of celery plants last year they didn`t get very big But I had enough for tuna sandwiches over the winter then I stuck them back out this spring. Wonder if I mulched them and covered them in deep snow if they might make it outdoors. Also no frost here yet!!! hows everyone else fairing
Celery is semy hardy like cabbage. Also, celery regrows roots. You can plant it again so to speak. This works even with store-bought celery. Regrown will not be the same like from seeds, but a fun plant indoors for sure.
