Gardeners plant flowers, shrubs and trees that can survive in their garden during typical weather. But what can a gardener do when the weather is anything but typical? Unexpected freezes can devastate landscapes and gardens. They can leave a gardener wondering how to protect plants from freezing, and question what is the best way to cover and keep plants from freezing.

At What Temperature Do Plants Freeze?

When cold weather comes your way, your first thought will be at what temperature do plants freeze, in other words, how cold is too cold? There is no easy answer to this.

Different plants freeze and die at different temperatures. That is why they are given a hardiness rating. Some plants produce special hormones that keep them from freezing, and these plants have a lower hardiness rating (meaning they can survive colder weather) than plants who produce less of this hormone.

That being said, there are also different definitions of survival. A plant may lose all its foliage during a freeze, and some can regrow from the stems or even the roots. So, while the leaves cannot survive a certain temperature, other parts of the plant can.

How to Protect Plants from Freezing

If you are only expecting a light freeze, you may be able to protect plants in a freeze simply by covering them with a sheet or a blanket. This acts like insulation, keeping warm air from the ground around the plant. The warmth may be enough to keep a plant from freezing during a short cold snap.

For added protection when you protect plants in a freeze, you can place plastic over the sheets or blankets to help keep warmth in. Never cover a plant with just plastic, however, as the plastic will damage the plant. Make sure that a cloth barrier is between the plastic and the plant.

Be sure to remove the sheets and blanket and plastic first thing in the morning after an overnight cold snap. If you do not do so, condensation can build up and freeze again under the covering, which will damage the plant.

When protecting plants in a freeze that’s longer or deeper, you may have no choice but to expect to sacrifice all or part of the plant in hopes that the roots will survive. Start by heavily mulching the roots of the plant with either wood mulch or hay. For added protection, you can nestle gallon jugs of warm water into the mulch each night. This will help drive off some of the cold that can kill the roots.

If you have time before a freeze happens, you can also create insulation barriers around a plant as a way how to protect plants from freezing. Tie up the plant as neatly as possible. Drive stakes that are as tall as the plant into the ground around the plant. Wrap the stakes in burlap so that the plant appears to be fenced in. Stuff the inside of this fence with hay or leaves. Again, you can place milk jugs of warm water on the inside, at the base of this fence each night to help supplement the heat. A string of Christmas lights wrapped around the plant can also help add additional heat. As soon as the freeze passes, remove the covering so that the plant can get the sunlight it needs.

Watering the soil (not the leaves or stems of the plants) will also help the soil retain heat and can help the plant’s roots and lower branches survive.

How to protect plants from frost: 10 quick and easy methods

(Image credit: Getty Images)

As the cold weather sets in, it's important to know how to protect plants from frost, as tender and young plants in particular can be wiped out by a sudden cold snap.

There are many quick ways you can protect more vulnerable plants and it's definitely better to be safe than sorry – there is nothing more devastating than seeing the beautiful plants you have lovingly nurtured destroyed seemingly overnight by a visit from Jack Frost.

Unless you live in a warm zone, it is likely that some of the ornamental plants and crops you have included in your garden ideas will be in need of some protection, so read on to find out how you can help their survival through the colder months.

How to protect plants from frost – which plants to protect

Not all plants in your backyard will need protection from the frost, but there are certain categories that will. These include:

Signs of frost damage include blackened, distorted or limp growth and the leaves turning green on evergreen plants and shrubs.

If in any doubt, research the conditions and hardiness of specific plants. Err on the side of caution and include frost protection in your winter garden ideas if cold weather is forecast in your state or area.

In terms of vegetable crops, there are some that actually benefit from a dose of frost and can taste better afterwards. 'There are some veg crops that are frost tolerant, if not frost resistant,' explains Nicole Burke, author of Rooted Garden .

If you live in a colder zone, it is therefore worth learning how to grow kale and other frost tolerant vegetable crops.

1. Bring potted plants indoors

There are many quick ways for how to protect plants from frost, and among the easiest is to bring potted plants indoors, especially tender container plants.

Potted plants are more susceptible to frost damage because they don't have the insulated benefits of of those planted in the ground.

Use a conservatory, garden room, garage, porch or frost-free greenhouse to overwinter potted plants – not somewhere that is too warm.

This can be a suitable option if you're wondering how to overwinter fuchsias in pots, or how to winterize hydrangeas, for example.

2. Add a layer of mulch on garden beds

'Apply dry mulch, such as chipped bark or straw around borderline-hardy plants, such as agapanthus, phygelius (cape fuchsia), hedychium and the architectural melianthus to protect the crown,' advises plant expert Sarah Raven . 

You could also use leaf mold or piles of leaves to add some extra protection on garden beds and provide a barrier against the cold.

3. Cover plants with fleece

You may wonder how to protect plants from frost when they are planted in the ground? One method – which is useful for larger garden plants and shrubs – is to cover them with horticultural fleece. You could use blankets or bubble wrap, too, to create a protective cover. These Amazon plant covers come highly recommended by reviewers. 

Place several stakes around your plants and then cover these with the chosen material to create a tent-like structure. Weigh down the corners to prevent the coverings from blowing away in the night and remove the covers during the day.

You can use this method for plants that require winter protection, such as agapanthus, cordyline and tree ferns.

'Fleece is very effective, but if you prefer something less obtrusive, a circle of wire netting filled with bracken or leaves will keep the cold at bay, too' advises Sarah Raven.

You can also wrap the trunks of young trees with horticultural fleece or blankets, such as if you're growing some of the best fruit trees or have mastered how to grow lemon from seed.

4. Place tender plants in a sheltered spot

The mantra 'right plant, right place' is relevant when considering how to protect plants from frost.

'Always plant half hardy and frost tender plants in a sheltered position, preferably near a south or west-facing wall, which will absorb heat during the day and radiate it at night,' advise the experts at Jacksons Nurseries .

'Eliminating the wind chill factor can substantially reduce the amount of frost damage incurred,' they add.

Other sheltered positions will include next to fences, under large evergreen trees for gardens, under the protection of pergola ideas or in patio or courtyard areas, as long as these also receive plenty of sunshine. 

While a sunny, sheltered spot is ideal for many tender plants, do not place early-flowering plants, such as magnolias and camellias, so that they are exposed to the morning sun. 'The rapid thawing of frozen buds can result in blackening and bud drop,' advises Guy Barter, horticultural expert at the RHS .

5. Lift and store tender perennials

Tender perennials that have bloomed and died down can be lifted to protect them from frost. 

Store the roots, bulbs, tubers and corms in a cool but frost-free place, such as a potting shed or greenhouse. There are lots of mini greenhouses to shop at Amazon , should you only have a few tender perennials to protect.  

This is a suitable method for how to overwinter dahlias or how to overwinter begonias.

6. Protect tender plants with a cloche

If you're wondering how to protect plants from frost in the vegetable patch, then a cloche is one of the best methods. A cloche can be used to protect seedlings and smaller plants from frost. 

Cloches are bell-shaped covers made from glass or plastic that can be placed over the plants. You can buy cloches or even make your own out of recycled objects. They also sell a range of cloches on Amazon .

'Cut-off large plastic bottles or milk containers can be turned into homemade cloches to embed into the soil around small plants and seedlings to provide protection,' advise the experts at Jackson Nurseries.

Remove them during the day to allow the plants to benefit from the warmth and energy of the sun.

Cloches are ideal for use with young vegetable crops that are sown in fall, such as broad beans, spinach, scallions or spring onions and asparagus.

7. Move plants into a cold frame

Young hardy annuals that are sown in fall may also benefit from some protection from frost.

Place them in the shelter of a cold frame over winter, although ensure they have good ventilation on warmer days.

You could make your old cold frame if you don't already have one, advise the experts at Jacksons Nurseries. 

To make your own temporary cold frame:

8. Water plants in the morning

You probably wouldn't think that your routine for watering plants could make a difference when considering how to protect plants from frost – but in fact it can help support any protective measures you take.

It is best to water plants in the morning during winter and when there is a risk of frost, because wet soil actually absorbs heat during the day and has an insulating effect.

9. Wrap containers

If you are unable to move containers indoors as a method for how to protect plants from frost, then try to protect them from the elements outdoors by placing the pots in sheltered areas, and where possible grouped together for added protection against the cold and wind. 

Container plants are more likely to suffer from their roots freezing. To prevent this, 'wrap the containers with bubble wrap from Amazon or straw, or bury the pots in the ground with just the rim showing, to benefit from the insulating properties of the ground,' advise the RHS experts.

Also raise containers using pot feet or by resting them on bricks to allow water to drain away more easily, and prevent plants sitting in icy water.

Choose the right plants for your backyard

(Image credit: Future / Camilla Reynolds)

Rather than trying to protect plants that are not suited to the climate of your backyard, instead choose those that are reliably hardy in the zone where you live. This will prevent the disappointment of losing plants when they aren't adequately protected.

Many evergreen shrubs and plants are fairly hardy. Plants will have a hardiness rating ranging from fully hardy – able to withstand temperatures of  0-10 °F (-18 -12 °C) – to frost tender, which might not survive being exposed to temperatures below 40-50 °F (4-10 °C).

While this might limit to some extent the plants or crops you can include in your garden, there will still be plenty of options suitable to you hardiness zone.

You can also include some of the best winter flowers to plant for color and interest in the colder months, or best winter plants for pots and borders.

What can I cover my plants with to prevent frost?

There are many materials that you can use to cover plants with to prevent frost.

You can find many permeable horticultural fleeces and frost protection products on the market, but can also use materials that you can find around the house – just make sure they are lightweight, breathable and insulating. 

Options to use include:

What temperature should I cover my plants for frost?

The temperature that you should cover your plants from frost to protect them will depend on the individual plants and the conditions and position in which they are planted.

Frost occurs in temperatures below 32°F (0°C) so this is the point at which you need to be protecting plants in winter. 

Most plants will need protecting from temperatures of 30°F (-2°C) or lower, but frost tender specimens should be protected before temperatures dip this low.

Can I use plastic bags to cover plants from frost?

It is not advisable to use plastic bags to cover plants from frost. This is because plastic can damage your plants if it makes contact with foliage, as it holds water against the plant and causes more damage from freezing. 

It also isn't a very insulating material, nor is it an eco-friendly or a sustainable option, so look for alternatives when deciding how to protect plants from frost.

How to protect plants on the site from frost?

Severe frosts can cause many plants to die quickly, so proper protection is essential. Fortunately, there are many methods that will allow them to survive the difficult winter period. We will talk about them in this article.

Protection of plants from frost. What should be done?

Before taking the first steps to protect plantings from frost, it is worth considering when we should really think about protecting plants in our garden. Indeed, if we do everything in this matter at the wrong time or too hard, we can do more harm than help - a protective layer at too high temperatures will lead to plant infection.

Therefore, protective mats and mats for plants are recommended to be used only at temperatures below -5 degrees. A certain indicator for us can also be the condition of the soil - if its top layer begins to freeze slightly, this is a signal for us that it is time to start appropriate preparation of our garden for winter.

It is important to pay attention to all newly planted young plants that are not yet sufficiently established. They are especially vulnerable in low temperatures and cold winds, and also need protection. In the case of perennial trees or plants resistant to frost, protection will be correspondingly less (and some of them will not need it at all).

How to protect plants in winter?

As noted above, there are many methods and products that we can use.

Mulching

This activity not only nourishes the soil and protects it from the development of various weeds, but also provides protection in case of strong temperature fluctuations and drying of the soil.

What is mulching? This is the process of covering the soil around plants with litter, that is, a variety of material - both natural and synthetic. This material essentially acts as a "coat" for our plants, and effectively protects the roots of plants from many harmful factors.


Before mulching, it is very important to choose the right materials, they are divided into organic and synthetic.

Organic Mulch Materials:
Synthetic Mulch Materials:

How to protect the plants on the site in winter?

In addition to the above materials, gardeners recommend considering ways to protect specific plant species:

How to protect perennials in winter?

Perennial plants, for the most part, tolerate frost well, and care for them does not cause any special problems. To protect perennials in winter, we can use leaves, sawdust, strois or bark. Do not forget to cover them very carefully - in frosts with temperatures below -5 degrees, the protective layer should be at least 10-15 cm thick. Another 10 cm should be added when the temperature drops below 10 degrees. In addition, it is recommended to regularly trim the shoots of perennials, until winter.

How to protect evergreens in winter?

Conifers and other evergreens are very cold tolerant, but the sun during this period can cause water to evaporate from them, which can cause plants to wilt because they cannot hydrate from the frozen soil.

All this means that evergreen shrubs and trees must also be protected in winter. To protect them, it is best to use a coating of non-woven fabric. Sawdust, bark and peat can also be effective. However, in no case should the leaves be used to shelter evergreens, because this will lead to rotting of the plants. Do not forget about intensive watering in the fall.

How to protect trees and bushes in winter?

With trees and shrubs in winter, everything is simple. At their base, you need to lay out earthen mounds, reinforced with a layer of leaves, bark or sawdust. You can also use an additional coating in the form of corrugated cardboard or non-woven mulch - these are special covers, usually made of straw. Thus, we guarantee trees and shrubs effective protection against severe frosts.

How to protect roses in winter?

Roses are delicate flowers and therefore need special protection in winter. Firstly, it is recommended to build earth mounds around them (preferably more than 30 cm high), and then fix their shoots. How? We can use nonwovens, corrugated board and straw mats.

How to protect your lawn in winter?

Preparing the lawn for winter is an extremely important step for every owner of the site, unless, of course, he wants to get unsightly rotted grass with melted snow in the spring.

How to avoid this? First of all, we must remove all fallen leaves from the surface of the lawn, which can rot and destroy its structure. Just before the winter cold, the grass should also be cut. If it turns out to be too high, such grass will become an ideal place for the development of various diseases, especially the so-called snow mold. Then it is worth using special fertilizers with a high content of potassium and phosphorus. Thanks to this, the grass will be reliably protected from the effects of particularly high temperatures.

How to protect plants in pots and containers in winter?

Many potted plants can overwinter not only on terraces. but also in the field. If the task is to take care of plants and flowers on the terrace, we can cover them from the cold with foam, ordinary foil or cardboard. If the plant is left to winter in the ground, it is better to cover it with tree bark or peat. For flowers wintering in large containers, the best solution would be to cover them with salt.

In addition to all the above protective actions, in winter we should carefully observe whether the plants are damaged by fungi, insects and typical winter diseases. If the plants are infected, treatment should be started immediately, because diseased plants will not be able to withstand frost and will definitely die.

If the winter in your region is without snow, rather dry and sunny, you should not forget about regular watering of evergreens. Otherwise, the water will evaporate, causing them to dry out. Constant monitoring of the condition of plants in winter will save them from many problems, including with the beginning of the spring season, so it is wiser to take into account all these recommendations and, if necessary, carry out their timely prevention.

How to protect the growth from spring frosts. Metodi zahistu

The weather is especially unstable in the spring. It can be warm during the day, and freezing at night. Why work, to save the tree from the inadmissibility of the tree, how to bloom?

How do you know what frosts will be?

In order for the garden to be in a good state, it is necessary to look after it and marvel at the weather forecast. And yet, there is no such possibility, following the memory, that the frosts will ring out in the morning and at night.

And also other officials, for which you can understand that it will be cold:

  • The sky at sunset is clear, and the temperature is +5 degrees.
  • Until 21.00 the temperature still drops to +4 degrees.
  • The temperature is dropping, the sky is gloomy, wind, atmospheric pressure is moving.
  • Such signs will help you to understand what it is necessary to protect the garden from the cold.

    Vicor growers grow in different ways.

    Finishing

    When the temperature drops low, you can spray the trees with lightly salted water. It is necessary that the entire crown be watered. Those drops, which seem to grow on the pagons, at low temperatures will gradually cool down, and if there will be frosts, the stench will give its warmth to leaves and flowers.

    You can use this method if you have stationary watering in your garden. Ale wine is less effective only if there is no wind. Otherwise it will be even hotter.

    Ukrittya

    Even if you have young or low trees you can open them. For tsgogo pіdіyde, like a special material, so sackcloth, wind up old ganchirka. It is necessary to wrap the tree and secure it with a spool. You need to work carefully. It is also necessary to know such a zahist low, so as not to harm the tickets, leaflets. Before speech, such a zahist can stand for a few days.

    Dimlennia

    One of the most effective ways. Slid to collect organic smittya, leaves, gorok, you can wind up trochs of water, and rule the bagattya right under the crown. Dim, who will be seen, create a zahisnu obolonka in the cold air. It is important that the fire itself is full of fire, but it’s not enough to deprive Yogo without respect for the whole night. Vіn mozhe zasnuti, or spread to the tree or budіvlі.

    Preparing and preparing

    The trees were not afraid of cold weather, they are processed with special treatments. Price can be:

    Custom processing can be combined with other methods.

    Watering

    Heavy watering can also be used to protect against frost. Sometimes it is necessary to simply water the growth well. Under the skin of the bush, wag 5-10 winds under a mature tree and 4-6 winds under bushes, grapes.
