I love strawberries, but I’ve never been particularly good at growing them. Last year I rescued a few sad-looking strawberry plants from one of my favourite discount shops and I’m happy to report that they have actually lived through the winter! In this article, I’m going to show you exactly how I managed to overwinter strawberries in my garden.

As a general rule, you can overwinter strawberries and yes, you can grow strawberries in a cold frame. You’ll need to make sure the plants are kept warm with some straw or similar material loosely placed on top during the coldest months.

So, how over winter strawberries in a cold frame? Let’s discuss.

Why Should You Overwinter Strawberries

There are many benefits to overwintering strawberries in a cold frame. One of the most important is that it can extend the strawberry season. This technique is most useful for gardeners in colder climates, such as the UK.

Strawberries can be overwintered by planting them in a cold frame and covering them with straw or hay for insulation. Strawberries are perennials, this means that they are not dependent on you for (too much) annual care and maintenance.

Strawberries are easy to grow, so this is an ideal way for new gardeners to get the idea of growing their own produce. If you want to add fruit to your diet but don’t want the hassle of growing it from seed yourself, you can start with strawberries.

They are also very pretty flowers and make a wonderful addition to flower beds!

What Is A Cold Frame?

A cold frame is usually a lightweight, transparent box that’s used for protecting plants from temperature fluctuations and exposure to the elements. Cold frames can be used indoors or outdoors.

When used indoors, the cold frame is built up to allow light to enter and keep plants warm during winter.

It’s usually made out of wood, glass or plastic and comes in various shapes and sizes.

Using cold frames give you control over how much sun your plants receive, creating a microclimate for plant growth

Growing Plants in a Cold Frame

A cold frame is an excellent way to grow strawberries and other plants throughout the winter months.

This is because they offer protection from frost and wind, which can be particularly damaging to strawberry plants during this time of year. They can be built with a few simple materials and will provide protection from frost and wind.

A cold frame is a fairly small garden structure, a box without a bottom. They cost very little to make and can be easily constructed from recycled materials. All you need is a few sheets of glass or plastic, some wood, and some slats to support the glass.

Why Growing Strawberries in a Cold Frame is Beneficial

Strawberries are a delicious and nutritious fruit that can be grown in a cold frame.

Growing strawberries in a cold frame is beneficial because it allows you to grow the strawberries during the winter months when they would otherwise not be able to grow. It also protects them from the elements, like wind and snow, which can damage the plants.

A cold frame is an excellent way to protect your plants from harsh winter weather.

They work by trapping heat in and keeping it warm inside at night while during the day they allow sunlight to come through. This helps keep your plants warmer than they would be outside in colder temperatures while still giving them access to sunlight for photosynthesis, which is how they make their own food.

How to Set Up and Grow Strawberries In A Cold Frame

A cold frame is a type of greenhouse that can be used to grow strawberries. It can provide protection from the cold and frost.

Cold frames are not heated, so they don’t require additional heating as some greenhouses do. They also don’t need to be as large as greenhouses because they’re insulated and have less heat loss than an uninsulated structure.

Cold frames are usually built out of wood, but you can also use sheets of glass, plastic or corrugated plastic siding. The basic idea is the same though –a small box that has an opening on top that allows sunlight to enter and heat to build up.

They’re pretty easy to make and don’t take long at all. Simply build your box, most people use one-story cold frames directly on the floor, but you can use shelves, and ensure the top of your box can be propped open or can be removed.

The top should allow light to come through. Some gardeners prefer the sires of their cold frame to let light in too, but this isn’t always necessary.

Once you have your cold frame built, place your strawberry plants inside (usually planted in pots or troughs for easy moving) and cover the plants with loose straw or hay during the winter months.

You will need to water your plants, but don’t water too much over the winter, just enough to keep them moist.

If you want to grow strawberries in a cold frame in your backyard or garden over the winter, this is a great option.

Strawberry Plant Care

Strawberries are a delicious and nutritious fruit that can be grown in the backyard, on a balcony or even indoors.

The strawberry plant is a perennial that grows best in the spring and summer seasons.

In order to grow strawberries in a cold frame, you should first prepare the soil by adding manure, compost, or your preferred fertiliser. Then, plant the strawberry plants about 2 feet apart and keep them well watered for best results.

In order to care for strawberry plants, you should water them regularly during dry periods of time (once every 3 days) and fertilize the soil with compost once a month.

Strawberries grow really well in pots and troughs too, which does make it easier if you’re doing container gardening. You can grow strawberries in a cold frame during the winter, and move them outside into the sunshine during the summer.

You can harvest strawberries when they ripen fully, and preserve any gluts you may end up with.

If you live in a cold climate, you might want to overwinter strawberries in a cold frame to extend your harvest season and build hardier plants.

When overwintered properly, most strawberry plants will survive down to -5° C (22° F), but they will only survive under cover and won’t produce fruit at that temperature.

Will Strawberries Survive Winter In Raised Beds?

A raised bed is another way to increase your chances of overwintering strawberries successfully by providing them with more support to grow on. This is a great way to make the most of your space.

You’ll still need to cover strawberry plants over the winter months and protect them from frost by using cloches and/or garden fleece.
