In the winter, you can use an unheated greenhouse to grow plants. It's a great way to keep your house warm and cozy without having to spend money on heating or cooling systems. But if you don't have an unheated greenhouse already, where do you start? There are tons of different types of plants that work well in these structures—some more than others—and it depends on what kind of area you live in as well as how much time and effort you want to put into caring for them over the long term. Let's take a look at some popular options!
There are several ways to use an unheated greenhouse in winter. Here's how:
Use a heater.
A small table-top heater
will keep your plants warm enough for them to survive, but not so hot that they need watering every other day (this can also be useful if you're growing indoors). If you want more heat, consider adding another layer of insulation around the base of your greenhouse using thick plastic sheeting or old tarpaulins covered with burlap or wool blankets.
Insulate and cover.
If you live somewhere cold where temperatures drop below freezing regularly during the winter months, then insulating your greenhouse
is essential—but not just because it'll keep your plants alive; insulation lets you store food inside without worrying about it rotting away before spring arrives! Covering up the walls and roof will help prevent ice build-up; this way there won't be any condensation dripping onto anything inside either!
What plants can be grown in the greenhouse?
You can use the greenhouse for growing fruits and vegetables, herbs, trees and flowers.
The main reason for using an unheated greenhouse
is that it is much cheaper than heating your home. In fact, you will be able to save up to 80% on your electricity bill if you build an unheated greenhouse in winter instead of installing central heating.
Fruits and Vegetables
The most obvious fruit and vegetable to grow indoors is the tomato. You can start them from seed, or you can buy young plants ready-to-plant at your local greenhouse or nursery. Tomatoes will require some extra care during the winter months, however: they need more light than other crops because they don't produce enough chlorophyll (a green pigment) in low light conditions to generate their own food through photosynthesis. They also prefer warm temperatures, so if it's below 40 degrees outside, move them inside!
If you live somewhere cold enough where there isn't a lot of sun to give them exposure during wintertime—or if your climate isn't very conducive for outdoor planting—you may consider using an unheated greenhouse as an alternative source for growing these foods year round
If you're looking to add some herbaceous flair to your winter garden, it's worth considering whether or not to grow herbs indoors. The good news is that all of the above-mentioned herbs are easy enough to grow in a greenhouse, and they can be harvested at any time of the year. If you live in an area where temperatures are consistently below freezing during winter months (or if you just want an excuse for fresh produce), then these plants make excellent candidates for growing inside.
The only caveat? They won't keep as long as their outdoor counterparts do—so don't expect them to last too long before being picked over by hungry herbivores.
Trees and Flowers
Flowering plants and trees that can be grown in your greenhouse:
Trees of all kinds.
You can use them to beautify your greenhouse, and they will help cool it down during the warm summer months.
Bulbs for spring blooms (like tulips).
These are a great way to add color to your greenhouse, but they do require heating to flower properly.
As you can see, there is no shortage of options when it comes to the types of plants that you can use in your unheated greenhouse. You can grow plants such as tomatoes and peppers that need more warmth than what a heated greenhouse provides. Or perhaps you want to grow some varieties of flowers that are less hardy than others? In this case, an unheated greenhouse would be ideal for them because they're not used to cold temperatures or harsh winds.
The bottom line is that you can use an unheated greenhouse
in winter with some plants that are hardy enough to survive the cold temperatures. As we mentioned above, fruit trees, deciduous trees and some herbs are good options. Before getting started, we always recommend doing some research on what will work best for your specific climate. In the meantime, feel free to visit our Youtube channel
