The Latest Girdling Method for Sugar Tangerines and Points to Note

Citrus fruit trees often use the girdling method when preserving fruit. It cuts off the phloem of the plant's trunk and main branches, retaining nutrients. With the root system temporarily lacking water and fertilizer, its growth is inhibited, thereby suppressing the sprouting of summer shoots and reducing the risk of fruit drop caused by competition between fruit and shoots for water and fertilizer. So how should sugar tangerines be girdled properly? Let's find out together.

1. Selection of Plants for Girdling

When girdling sugar tangerines, you must first select suitable plants. Not every sugar tangerine tree is suitable for girdling. You should choose those with strong tree vigor, dark green leaves, fully matured spring shoots, and a tendency to sprout summer shoots. For weak plants that are poorly managed, lack nutrients, or suffer from severe pests and diseases, girdling is not suitable, and it may even cause the tree vigor to weaken further and yield to drop severely.

2. Suitable Time and Method

For fruit preservation after the flowers have fallen, treatment should be differentiated according to the strength of tree vigor and the number of flowers. Generally, one treatment is applied. For fruit trees with vigorous growth and few flowers, generally two treatments are applied, the first at the end of flowering and together at the end of the physiological fruit drop. For girdling, it is recommended to cut two-thirds of a large branch or main branch; large branches in the middle and lower part of the canopy should not be cut. After girdling sugar tangerines, the wound takes half a month to heal, so girdle once every half a month, while girdling wounds that need 30-50 days to heal have a better fruit preservation effect, and one girdling is enough to achieve the purpose of fruit preservation.

3. Points to Note for Girdling

Girdling must be combined with other agricultural techniques. If fertilization management is neglected after girdling, tree vigor will weaken and yield will decline. Therefore, when girdling, attention should be paid to the level of fertilization and the growth vigor of the planting to decide whether to girdle and how many times to girdle. Girdling too early and too many times, with excessive fruit preservation, causes tree vigor to decline and even plant death; while girdling too early and too many times very easily leads to the phenomenon of alternate bearing. Many fruit growers begin girdling after the flowers have fallen, girdling once every 10-15 days, and even girdling continuously during the peak of the second physiological fruit drop, which very easily makes it difficult for spring shoots to turn green, results in an excessive fruit set, prevents autumn shoots from emerging, and forms alternate bearing.
