How to care for apricot trees in winter

Pruning and shaping

Winter pruning of apricot trees is pruning during the dormant period. The focus is on pruning diseased and weak branches, dry branches, and overgrown branches to promote the formation of fruit buds as soon as possible. At the same time, trim the tree shape reasonably, pay attention to the opening angle, and maintain good lighting and ventilation conditions. Be sure to protect the wound in time after pruning. You can apply appropriate medicine to speed up wound healing and prevent the wound from drying out.

Garden cleaning and frost prevention

Qingyuan

Remove fallen leaves, cut off diseased branches, dead branches, diseased and insect-infested branches, and burn them in a centralized manner. Remove surrounding weeds to prevent the source of disease and eliminate overwintering insect eggs. Remember to apply an oil "wound healing antiseptic film" to the wound in time to promote its healing.

Insulation and antifreeze

Spraying the trunk and branches of apricot trees with 100 times diluted "Tree Protector General" can kill bacteria, disinfect, keep warm and prevent frost. A total of two sprayings are required, one before the soil freezes and one in early spring.

Pest control

Scrape off gum disease

Gummosis is a common disease of apricot trees, which affects fruit yield and quality, and in severe cases can even cause the death of the entire tree. To prevent and control gum disease, you must first scrape off the gum, then apply "Tree Protector General" lotion on the wound to make the diseased skin fall off quickly and prevent the invasion of bacteria. In order to eradicate gummosis, the girdling technique can be used in winter to apply the cationic active agent "Flower King No. 2" to the apricot trees to control their growth and achieve a preventive and therapeutic effect.

Control of borer

The method of inserting poison sticks is usually used to prevent and control borer, which is more effective. The specific operation is to first sharpen one end of the wooden stick, then dip it in pesticide, and then insert it into the insect mouth. This can not only block the defecation channel of the borer, but also poison the pests deep in the tree.
