How to predict frost
Forecasters cannot always correctly predict the occurrence of frosts. The decrease in temperature is different in areas of the same region. Summer residents know that even a slight cold snap is dangerous:
- -1 ° С - the ovary dies;
- -3.5 ° C - blossoming buds freeze;
- -3 ° С - buds will not open;
- -2 ° С - flowers freeze and fall;
- -1.5 ° C - fruits will not develop from flowers.
Gardeners have learned to recognize impending frosts in the spring by signs:
- gets colder in the evening after a hot day;
- the wind dies down;
- the sky becomes clear, bright stars appear;
- birds and frogs become silent;
- there is no dew in the morning;
- atmospheric pressure rises.
Cover vegetables with plastic wrap. The situation with trees is more complicated. Gardeners offer 4 ways to protect trees from sudden cold snaps.
Smoke in the garden
The oldest and most proven way to protect crops from frost is smoke. Summer residents prepare firewood, straw, cut grass, branches, foliage in advance. Several bonfires are made in the garden in the evening on the leeward side of the site. The main thing is to create thick smoke, it is the creeping smoke that will save the plantings from the frosty cold. Gardeners warn that the coldest temperature is in the morning. If you want to save the harvest, you have to keep the fire going until it gets warmer, finish making fires after sunrise.
Sprinkling the area
The second way to save trees is by sprinkling. A spray nozzle must be put on the hose. Trees are watered several hours before severe frosts. This is usually done at night. Some gardeners suggest shedding well around tree trunks during the day. After abundant watering, it is necessary to cover the watered part of the earth with foil. Later, the film is removed, steam rises from the soil, thereby protecting the crown of the tree.
Shelters from frost
Small trees can be covered with foil and burlap at a temperature of at least 5 degrees below zero. Any material will do, the main thing is not to break the branches. Summer residents put a cover on the crown of a tree and fix it on the trunk. When covering a tree, you do not need to strongly tie the material to the tree or reinforce it with sticks and stones. Don't worry, there is no strong wind in cold weather. The disadvantage of this method is that you need to find a large amount of covering material if there are many trees in the garden. It is almost unrealistic to cover a large tree.
Fertilizers that save from a cold snap
Fertilizers can save trees. But for this you need to know when to expect a cold snap. Fertilizing is carried out a day before the cold weather. Spray with a solution of superphosphate and potassium nitrate. If you applied phosphorus and potassium in the spring, then this way you helped the trees become less vulnerable.
Actions after frost
Trees need help after cold weather. Leaves and flowers are treated with anti-stress drugs. Zircon is able to improve their condition. Frozen flowers can no longer be reanimated, but those that did not have time to open may still move away. Experienced gardeners plant trees with different flowering times to help protect them from frost in May.
