Which parts of fruit trees are prone to frostbite in winter

Cold winters are often a hard season for fruit trees, and some freezing disasters tend to occur in concentrated outbreaks. The most common problem for fruit trees is frostbite of the tree body, so which parts of fruit trees are more prone to frostbite? Let's find out together.

1. Branches

Branches have always been a part of fruit trees that is relatively prone to frostbite, because the branches of fruit trees are relatively thin, have low resistance to low temperatures, and are widely distributed, so when cold air strikes, they receive cold air over the widest area. Branches are also the hardest place to protect from the cold, so in the face of cold winter air, growers can remove some of the relatively thin and weak branches in advance to reduce the tree's nutrient consumption and allow nutrients to be used to the greatest extent.

2. Trunk

Freeze damage to the trunk of fruit trees generally occurs in trees with relatively thin bark. It is mainly caused by the nutrient transport channels in the bark being frozen, so nutrients cannot be supplied to the tree body, leading to death by freezing. Fruit trees such as pear trees and peach trees are relatively prone to this situation, because their trunks are not thick and sturdy either and cannot effectively protect against the cold, so external materials are generally needed for cold protection. A common method is to add a outer wrapping to the trunk, that is, using materials such as straw to bundle it for cold protection.

3. Roots

Root damage is relatively the most serious, first because it is not easy to detect, and second because it is inconvenient to treat. It is mainly caused by frostbite due to excessively large temperature differences in winter. When it is cold, snow water covers the surface layer, then as the temperature rises, it melts into the soil, and then as the temperature drops, the roots are frostbitten. Therefore, in winter, attention should be paid to waterproofing around the root area. It is best to dig a drainage trench around the roots, which can effectively prevent freezing.

4. Trunk neck

The trunk neck, that is, the part above the soil, is one of the parts most susceptible to freeze damage in daily life, and it is also one of the main points for cold protection. In daily life, people see white powdery substances distributed on this part of some fruit trees; those are cold protection methods used. This is the junction of soil, air, and water vapor, where microorganisms are extremely active, and it is most susceptible to cold air invasion in winter, so the first place for cold protection is here.

The above are some of the parts of fruit trees that are prone to frostbite. Generally speaking, as long as there is no freeze disaster, fruit trees basically do not need cold protection, and some fruit trees can still resist pure snow. If it is rain and snow, then attention should be paid to cold protection, as it is relatively likely to frostbite fruit trees.
