I know all of you like to grow various plants, but when winter comes, everyone who grows flowers starts to worry about whether their potted flowers will freeze to death. So let’s share how to grow potted plants in winter protects them from freezing.

4 points to consider to prevent freezing of potted plants in winter

Room temperature

If you want potted plants to spend the winter safely, moving the potted plants into a warmer room is the essential thing. Otherwise, the potted plants left outdoors will be frozen due to the temperature difference between day and night or cold waves.

Generally, it is more reasonable for the indoor temperature to be stable at about 15 degrees Celsius. Therefore, this temperature will not be too high and will not be frozen.

Lighting

The potted plants that are moved indoors still need light. The intensity of sunlight in winter is low. The potted plants should also increase the daily light time accordingly and receive longer light to maintain normal. Otherwise, there will be abnormal conditions due to long-term darkness.

Watering

Watering is also an essential part of antifreeze work. In winter, the temperature is relatively low, and most potted plants consume water at a slower rate.

Therefore, we should reduce the frequency and amount of water when watering and ensure that the water temperature is similar to the soil temperature to prevent water from freezing in the soil and damaging the plants.

Cover

If the temperature drops too fast or the cold wind blows the potted plants during ventilation, we should adequately wrap and cover the stems and roots of the potted plants. Make sure the roots are close to the ground surface covered with plastic film or straw. It will prevent the roots from freezing.

Antifreeze measures for planting flowers and trees on the ground

Plum tree blossoms

To prevent freezing plants from winter, you can wrap the stalks with thermal insulation materials to keep them warm. You can use materials such as straw, wheat straw, old cloth, and old cotton wool.

In early winter, trenches can be dug around the roots of these outdoor flowers and trees, watered once with fertilizer, and then filled with soil to protect the roots. The branches of flowers and trees that overwinter outdoors can also be painted white, effectively preventing freezing damage and preventing and controlling the diseases and insect pests that remain on the branches.

However, you should note that the quicklime must be turned into slaked lime before use for the whitening agent prepared with quicklime. Otherwise, it will burn the branches of flowers and trees.

The preparation ratio of whitening agent: 36-40 parts of water, 10-20 parts of quicklime, 1-2 parts of table salt, 2 parts of clay, and 2 parts of lime sulfur mixture stock solution. First, dissolve and mix the quicklime and salt, then pour in the lime sulfur mixture and clay, and after stirring evenly, it can use for whitening.

In case of severe cold currents or rainy and snowy weather, you can cover these plants with plastic films or other warm materials. Then wait until the weather is clear and uncover to keep the seedlings stocky.

Antifreeze measures for bulbous plants

Canna flower

Bulbous plants that need to overwinter outdoors and underground can be covered with compost soil, rotten leaves, dry grass, etc. Pay attention to keeping the bulbs under the permafrost layer. Otherwise, the bulbs will be frozen and damaged. It cannot germinate new shoots in the next spring. Note that the mulch must not contain germ eggs.

Antifreeze measures for tall garden plants

Tall privet tree

To prevent tall garden plants from freezing in winter, wrap straw ropes on their trunks and large branches. Also, you can wrap a 10-20 cm wide polythene ribbon around the outer edge of the straw ropes from bottom to top in a clockwise direction. The film can prevent freezing damage to the trunk and large branches of the plant.

Antifreeze measures for cold-resistant potted plants

Bonsai tree

For outdoor insulation of cold-resistant potted flowers and tree bonsai, the best way is to bury the pots below the outdoor permafrost layer to prevent the roots from freezing damage. you can also cover the pot surface with plant ash, which not only has a good thermal insulation effect and has no side effects on flowers and trees.

The flowers and trees that survived the cuttings in that year are small and have poor cold resistance. Therefore, except for the main branches and leaves to receive sunlight, the rest of the branches should be wrapped and covered with thermal insulation materials. To keep warm, you should also cover the potting soil with grass ash or other thermal insulation materials.
