Pruning treatment for frozen leaves and branches
This article introduces the experience of maintaining green plants, such as what to do with potted plants that have not been moved to a warm place in time due to sudden temperature drops. Let's find out the introduction by the editor.
Suddenly, one night the spring breeze comes, a thousand trees and a million trees pear blossoms. What a wonderful picture, but for many flower friends, it is quite worrying because many potted plants have not had time to move indoors before the snow falls, and there is a concern that the potted flowers will freeze to death.

If you have not moved your potted plants indoors in time before, you can take some rescue measures after snowfall to avoid severe frostbite in the potted plants.
1. Move to a warm place in time
"It's not cold when it snows, but it's cold when the snow melts," so don't think that your potted plants have been covered with thick snow, but it doesn't necessarily cause frostbite. For evergreen potted plants or potted plants in bloom, clear the accumulated snow in time before it melts, and then move them to a warm room.
When the weather is sunny, you can place the potted plants in a place where they can be exposed to sunlight to receive the warmth of the sun, which helps the potted plants recover. For example, hanging orchids, pansies, etc.
If it's a potted plant with a certain cold tolerance, you can clear the accumulated snow and place it in a sheltered and sunny spot. For example, large-flowered hydrangeas, with cold tolerance above -10 degrees, can survive the winter in a sheltered and sunny spot without moving indoors.
2. Pruning treatment for frozen leaves and branches
If the potted plants have frostbite, leaves or branches that have been frozen should be cut in time. Especially for some succulent stem plants, such as meat trees, longevity flowers, Marguerite daisies, and geraniums.
If the branches and leaves have frostbite, they should be cut in time to prevent rot and infection of the branches, leading to the withering of the entire plant.
3. Water and fertilizer control
Whether it's potted plants moved indoors or potted plants overwintering in a sheltered, windy spot, attention should be paid to controlling watering. For varieties with poor frost resistance, slightly drier potting soil can tolerate lower temperatures. For potted plants indoors, due to poor indoor ventilation, it is also necessary to control watering and water only when the potting soil dries.
For some light-loving plants, such as bougainvillea, if maintained in a warm room during winter, it is important to control water and fertilizer. If the water and fertilizer are abundant, there will be excessive growth, and the winter sunlight intensity is not enough, which can lead to more severe excessive growth, causing the plant to become weak, so it is necessary to control water and keep the potting soil slightly dry, avoiding nitrogen fertilizer.
4. Clearing snow to prevent broken branches
In addition to paying attention to cold-tolerant potted plants, we also need to pay appropriate attention to outdoor, cold-tolerant tall plants. If there is too much snow accumulated, it is necessary to knock the snow off the branches in time.
If left unattended, many plants have not had time to shed their leaves, and thick snow on the branches can easily break them. For example, if the long branches of our climbing roses are broken by the snow, it would be a great pity.
