Winter-Friendly Plant Ideas That Are a Great Addition to Your Greenhouse!

A DIY backyard greenhouse adds personality and accentuates the beauty of your garden, don’t you agree? These structures are perfect when it comes to protecting your plants, especially when they’re at their most vulnerable - the winter! 

Now you might assume that there’s nothing much you can do in your greenhouse from October to March. But, on the contrary, there are plenty of plants that will thrive even during colder months so long as you take the right precautions.

To successfully grow these plants, you’ll first need the right DIY greenhouse kit! If you’re in the market for a sturdy greenhouse kit in Canada, Planta is at your service! We offer compact and practical solutions for flowers, fruits and produce right in your own backyard. No, you don’t need to be a commercial whiz to buy a greenhouse from us. . 

Regular homeowners can easily build one of our products using the step-by-step included manual. Our greenhouses are sold all across Ontario and have become popular across North America as well. They have received rave reviews from homeowners and commercial landscapers alike!

What are greenhouses made from? All Planta’s models are created from galvanized steel and heavy-duty polycarbonate. This makes them rust- and snow-resistant and able to withstand Canada’s harsh weather.

Without further ado, let’s explore the types of plants that will make a great addition to your backyard greenhouse in the winter. 


Depending on the variety, this kind of vegetable can survive in temperatures as low as -6°C. The best part about growing kale in the winter is that it is sweeter as the vegetable generates sugars to protect itself. When temperatures delve lower than this, you’ll require a greenhouse that provides adequate heating.

Which greenhouse works best? Our array of Sungrow Greenhouses are ideal for growing kale and other similar produce. These can support up to 6ft of snow and withstand 100km/hr winds.


Hardneck garlic, as opposed to soft neck garlic, grows well during the colder months. When you put these in a pot, they can be moved out of the greenhouse when the weather gets better. During the months of March and April, you can then transplant these to give them more room to grow and acquire larger cloves!

Which DIY greenhouse kit works best? We recommend the Astra Greenhouse to grow your garlic during the winter. This is a heavy-duty, cold frame structure designed specifically for backyard farming.

Cabbage & Broccoli

These are cold-month vegetables and can easily survive in temperatures that hover around the 10°C mark. In fact, cabbage and broccoli don’t do well in warmer climates as that stunts their growth. Therefore, it’s best to get started on these in Feb or March to prepare them to be planted during the spring. 

Which DIY greenhouse kit works best? The Ministar Greenhouse is extremely versatile and boasts of straight clean lines to offer ample space for your cabbage and broccoli in the winter. This elegant design is the perfect addition to your backyard. 


When it comes to potatoes, plan for a January planting so that they are ready to harvest in March. As potatoes are vulnerable to frost, you need a sturdy greenhouse that can be heated. 

Which DIY greenhouse kit works best? Our Sigma Greenhouse is perfect for all 3 seasons of gardening for flowers, fruits and vegetables. This is particularly great to keep produce warm during the winter while affording plenty of room for it to grow unhindered.  


When you plant carrots in the fall, they will be ready for harvesting as soon as the weather breaks and the ground thaws. It never hurts to double-check the variety of carrots you’re getting to make sure they are cold-friendly. 

Which DIY greenhouse kit works best? When it comes to growing carrots, our collection of Sungrow Greenhouses is ideal for backyard farming, especially in limited quarters. In addition, these are able to withstand harsh Canadian winters and come with a rust-resistant frame. 


Typically peppers need a temperature of 12°C or higher to grow just right. However, if your greenhouse is well-insulated, you can grow peppers all year round without worrying about the elements getting to them. You could even choose to keep them in your greenhouse during the colder months and then transplant them outside in May. 

Which DIY greenhouse kit works best? To grow peppers successfully during the frostier months, try the Sungrow Greenhouse collection. These can take a snow load weight of 360 kg/m². Made from galvanized steel, you can install your greenhouse with or without a base.
