How to Overwinter Plants

A new round of cooling has caused the weather to freeze suddenly. It is very important to keep the plants alive during the winter. There are many common ways for plants to survive the winter.

1. Winterize with fallen leaves

The principle is to quickly produce hibernation hormones and inhibit growth to prevent excessive consumption of nutrients. Secondly, abscission cells are produced in the lower part of the petiole, which can also cause the leaves to fall off quickly to reduce nutrient consumption.

2. Overwintering with seeds

It usually occurs in root, stem and leaf plants, such as leeks and lotus roots. However, these plants generally adopt two ways to fight against the severe cold. The first is to produce seeds to pass on the family line, and the second is to "lose leaves to survive."

3. Use waxy film or grease to survive the winter

This is also a common way for evergreen trees to spend the winter, which is mainly similar to pine trees, cypress trees, etc. They tend to secrete a layer of wax on the surface of their bark and leaves, which can keep out the cold while preventing their own water from evaporating.

4. Use roots to survive the winter

The principle is that some plants can convert protein and starch into sugar and dissolve it in water through the action of saccharifying enzymes in their bodies, thereby increasing the concentration of plant cell fluid, making it difficult for cell tissues to freeze, thus increasing the plant's ability to resist cold.

5. Overwintering with seedlings

In fact, the plants first accumulate a large amount of nutrients when winter is approaching. With the arrival of autumn, the trees lose their transpiration function and reduce the dissipation of heat and water in the body.

How to manage plants in winter to survive the winter

1. Bag to keep warm

When the temperature drops, we can put a plastic bag on the plants. The plastic bag can keep them warm, especially at night when it will be colder. You can put on the plastic bag before going to bed.

However, it is easy for water vapor to appear when putting plastic bags on plants, so the plastic bags need to be opened during the day to prevent the water vapor inside from damaging the roots of the plants.

2. Cover with thick soil

We can also cover the roots with a thick layer of soil. The deeper the soil, the less likely it is to be frostbitten. The soil can also play a role in heat preservation, but the soil needs to be kept loose, which is more conducive to the breathing of plants.

Covering with a thick layer of soil will prevent water accumulation, and watering must be done thoroughly to prevent water accumulation due to the heavy soil.

3. Apply base fertilizer

As the saying goes, "Applying a layer of fertilizer in winter is like covering yourself with a quilt." Winter fertilizer can be used in spring to prevent cold and keep warm. Before winter, plants are usually repotted. At this time, we can apply a layer of base fertilizer in the potting soil, which is more conducive to plant growth. Moreover, the nutrients in the fertilizer can promote the growth of plants more vigorously and improve the frost resistance of plants, which is also very beneficial.

4. Spray antifreeze

After diluting it with water, spray it directly onto the surface of the plant. Antifreeze can increase the vitality of plant cells, allow plants to produce cold resistance factors, and improve the plant's own ability to resist freezing.

However, antifreeze is not available in all areas, so choose according to the actual situation. For example, in a place like Harbin where the temperature is relatively low, if antifreeze is sprayed, the water will soon be frozen on the leaves of the plants, causing frostbite to the plants.
