Grow vegetables all winter long
The good news is that growing vegetables in winter, when the temperature is cold often makes them taste better. Most of the plants on our list are hardy in temperatures well below freezing.
|Kale||Thrives in cool climates some varieties grow in freezing temperatures and cold greenhouses||Unheated greenhouse Row cover|
|Spinach||Grows slowly over the winter for an excellent early-spring crop||Low tunnel cold frame|
|Lettuce||Eat homegrown salad all winter long Some varieties can survive temps down to 10°||Cold frame heated greenhouse|
|Cabbage||Can withstand frost down to 10 to 15°||Row cover|
|Green onions||Very hardy — frost will not kill them prefer cooler temps throughout the winter for a perfect early-spring crop||N/A|
|Collards||Plant in late summer to early fall for a winter crop flavor improves with frost||Unheated greenhouse Cold frame|
|Asian greens||Many varieties of Asian greens love cold weather||Unheated greenhouse Cold frame|
|Corn mache||AKA lamb’s lettuce can be sown directly outdoors in many climates||Row covers|
|Carrots||Can survive in temps down to 15°Become sweeter after a frost||Straw to keep the soil from freezing|
|Beets||Seedlings love cool moist conditions will grow outdoors in milder regionsExtreme cold will cause the beets to go to seed||Cold frame|
|Radishes||Winter radishes can grow to several pounds each cold weather causes the flavor to become sweet Can survive a deep freeze||Straw to prevent freezing|
|Garlic||Grows slowly all winter for a delicious early-Summer harvest||Straw|
|Austrian Winter Peas||Can survive in temps down to 10° Very fast growth cycle||Cold box or tunnel in colder climates|
As you can see, some of the winter-time vegetables have long growing seasons, and you won’t see results until spring. However, other varieties will produce greens and veggies all winter long provided you protect the plants correctly.
You’re going to hear the term “hardiness zone,” when it comes to your location and planting seasons. If you’re unsure which zone you’re located in, check out this map from the United States Department of Agriculture (USDA).
- Can I grow vegetables indoors for the winter?
It’s possible to grow veggies right in your own home over the winter. If you are interested in growing vegetables in winter, you’re likely going to need a grow light like these as well as a location in your home for the plants. For a detailed article on indoor gardening, check out this how-to guide from the Spruce.
- Can I grow vegetables in a greenhouse during the winter?
- Many of the plants on our list are hardy at temps well below freezing and would grow wonderfully in a greenhouse. However, if you want to start growing vegetables in the winter, you’re going to need a heated greenhouse, especially if you live in a colder region.
- Will a greenhouse keep the plants from freezing?
A greenhouse traps heat during the day and will usually keep plants from freezing. However, if temps dip below a certain point, you have to take some steps to keep the frost from the plants. Check out this how-to guide from SF Gate.
One of the first things you will need to learn about growing vegetables in winter is this — even if the plants can stand sub-zero temps, if the soil becomes frozen, nothing is going to grow. So, if you live in the green, purple, and blue zones, you’re going to need a season-extender.
A season-extender is anything to keep the soil from freezing and your plants from succumbing to freezing temps. Above all else, the ultimate plant-killer tends to be ice so you need to keep them dry.
Try one of the following season-extender ideas:
- Cloche for individual plants
- Floating row covers
- A clear umbrella placed over a raised bed or tub
- Transparent storage bins
- Polyethylene sheeting: use rocks to hold it down and fence posts to prop up as needed
- Greenhouse: you can find DIY instructions like this video online
- Cold frame: you can purchase a pre-made or build your own using a video like this
- Small polytunnel greenhouses: you can purchase kits or do-it-yourself
The season-extender you choose depends on several factors:
- How many vegetables you want to grow
- How tall the vegetables are going to get before you harvest
- The climate where you live
- Average snowfall (some places get too much snow for a smaller plastic cover to hold up)
Don’t make the common mistake many people do and assume that you can simply let your winter plants go. If you’re using a season-extender, you’re going to need to make sure and open it up on sunny days so the plants can get some air.
If you don’t air them out, the plants won’t grow properly. Check out this detailed article about season-extenders from The Empress of Dirt.
Finally, remember, most of the plants on our list today like moist soil. While it won’t dry out as quickly as it does during the summer, your plants are going to need to be watered now and then.
