How To Keep Plants Warm in Winter?

Do you want to keep your plants warm in winter as they can be in danger of dying during the cold months?

Plant growth might be difficult due to shorter days, lower temperatures, and chilly air.

As the temperature drops, many houseplants have a modest response that causes their leaves to turn yellow or die.

Your plants shouldn’t be left outside in the cold throughout the winter for a variety of reasons including frost, heavy snowfall, rain, and brisk winds.

You’ll find this brief guideline useful if you’re unsure of what you can do to keep your winter vegetables or plants warm during this chilly season.

Ways of Keeping Plants Warm in Winter:

1. Control the humidity in your house:

The temperature falls as does the relative humidity.

Spray the plants frequently or install an air humidifier because this feature is crucial for tropical plants.

Smaller plants benefit from the moisture- and heat-saving effects of placing a glass bell chamber or recycled plastic bottles.

2. Cover your plants:

Because it doesn’t raise the temperature significantly, covering your plants with a drop cloth or old blanket can be beneficial during the colder months.

Spread it out evenly and make sure it doesn’t contact any of the plant’s branches or leaves when covering your plants.

Open up during the day to give them the most air and light possible.

3. Improve the way you water:

The majority of plants, especially those that are indoors, require less water over the winter.

Overwatering should be avoided to prevent root rot.

When watering indoor plants, stay away from using cold water.

Use water that is at a reasonable temperature to avoid startling the roots.

Before watering your plants in the winter, make sure the tap water isn’t too chilly and warm.

4. Use Mulch to Protect Your Plants:

Applying mulch or hay will help insulate your plants. As a result, the roots of the plants are safeguarded and moisture and heat are retained.

Adding jugs of warm water to the mulch will also provide additional protection from the cold.

Better insulation is provided by moist soil.

Make sure to add an insulating layer on top to stop the soil from freezing to the roots.

A natural barrier that insulates and retains heat and moisture is made by a layer of mulch that is a few inches thick.

Mulch layers also guard against heavy snowfall or rain from compacting the soil’s structure.

Grow mats placed over topsoil or sheep’s wool gardening fleece also offer sufficient protection.

5. Place plants in greenhouses:

By putting them in a greenhouse over the winter, plants can be kept in the best condition possible.

While shielding against wind, rain, and frost, glass panes let in the warmth of the sun by suspending bubble wrap or cloth, you can try to enhance insulation.

Smaller, simpler-to-heat areas are created by dividing the greenhouse in this way.

Use space heaters as an alternative to reduce humidity and keep the temperature steady.

6. Take them inside:

Tropical plants can be kept inside all year long since they are perennials, even though they frequently act like annuals in temperate and subtropical climates.

Tropical plants thrive near windows or glass doors that are bright, but placing them close to heat sources is to be avoided.

7. Dig them up:

If you have snow, you can dig up your tuberous perennials and let them dormant until spring.

 It would be easiest to simply pot them and keep them permanently indoors, where the temperature is always comfortable.

8. Plants can be protected in the warm winter by pliable soil:

The health of the roots and the entire plant depends on a substrate that drains efficiently.

Cold temperatures and saturated soil can promote disease, mildew, and root rot.

Regular soil moisture also encourages the development of shallow roots, which damages plants and makes it easier to uproot them.

Due to the possibility of uprooting in severe winter gusts, outdoor plants are affected.

To ensure that your garden has everything it needs to flourish over the winter, safeguard your plants with a growing medium that retains water well and drains efficiently.

Because it is inherently sterile, coco coir reduces the likelihood of pests or disease spreading, and it keeps a structure that is adequately ventilated to encourage strong root growth.

How Can Trees Be Safe from Freezing Conditions?

During storms, freezing winds regularly pelt tree trunks, killing many of them.

Here are some tips to keep the plants warm in winter so they stay cosy and content:

1. Cover the Trunk:

Like humans, a tree will be protected from frost damage by covering exposed areas like trunks.

It can be covered with a variety of materials, including commercial tree wrap, plastic tree protection, burlap nets, and discarded potato sacks.

2. Wrap the Canopy Up:

For young trees, it is advised to maintain leafless or evergreen canopies for at least 1-2 winters after planting.

To prevent freeze, and burn and keep them warm during severe weather, simply encase the top in plastic. The higher branches can be wrapped with the same materials.

3. Develop A Wind Barrier: 

It is possible to lessen the cold damage caused by wind gusts to the trunk and young trees by constructing a barrier as a plant warmer for the winter.

This barrier can be formed from various porous materials, such as burlap.

4. Shield the Roots:

The anchoring organ of the plant also needs to be kept warm.

Leave a few inches between the tree’s primary trunk and the outer canopy and pile some shredded bark on top of the tree.

FAQ- How to Keep Plants Warm in Winter?

Q1. When is the temperature too low for my plants?

Tender plants will die with a light freeze or 29 to 32 degrees Fahrenheit.

The majority of plants are severely damaged by the moderate freeze, which is between 25- and 28 degrees Fahrenheit.

 Most plants are severely harmed by a severe or harsh freeze when the temperature drops below 25 °F.

Q2. For my plants, should I purchase a heater?

It is becoming more and more crucial to purchase a couple of high-quality space heaters if you want to keep plants warm during the winter.

These heaters will offer the heat your plants require to be healthy.

Q3. In winter, how frequently should I water my plants?

However, as a general guideline, you may anticipate watering most plants once or twice a week during the spring, summer, and autumn and once a week or fortnight in the winter.


The above-mentioned advice can be useful if you’ve had trouble to keep your plants warm over the winter.

Always bear in mind that caring for your plants entails more than just keeping them warm in the winter.

You should also spend money on quality fertilisers.

Anyone who owns indoor plants should get one that meets their demands.
