What are the times and precautions for spring bud removal in citrus?
Spring bud removal in citrus is done to extend its lifespan. Manually removing the young buds of summer shoots and autumn shoots stimulates the surrounding buds to sprout. When bud removal is stopped, the tree is allowed to sprout and send out shoots, which is called "releasing shoots." So when is the best time to remove buds from citrus in spring? And how should it be done? Let's take a look together.
1. The best time for bud removal
Spring bud removal in citrus is generally done in the year before fruiting, when summer shoots and autumn shoots should be released, and timing is very important at this point; the sprouting of summer shoots must not be delayed. Summer shoots can be released in May, and autumn shoots in mid-September. In some regions, due to the influence of temperature, summer shoots can also be released in mid-July. Releasing shoots too early or too late will affect the tree's production and growth. For spring bud removal in citrus, it is best to choose clear weather. Before removing buds and releasing shoots, the fruit trees should be fertilized, and if there is a water shortage, they should be irrigated in time, because drought will reduce sprouting. Spring bud removal has relatively high requirements. If shoots are released too early or too late, it will not only increase the number of bud removal operations, but also cause more losses to bud removal, leading to a large reduction in nutrients, while also increasing labor.
2. Bud removal methods
When the young buds of summer and autumn shoots are removed, it stimulates the sprouting of secondary buds. You must wait about a week before removing the newly sprouted young buds from the new shoots, and then they sprout again. The more you remove, the more they sprout. Bud removal continues until the new buds meet the requirements, at which point bud removal is stopped and the tree is allowed to send out shoots.
3. Precautions for bud removal
The summer shoots or autumn shoots retained after bud removal not only sprout well, but are also numerous and uniform, which increases the number of fruiting mother branches and thereby increases the yield of young trees. Therefore, releasing shoots is best carried out in the year before fruiting. For young trees that have just begun to bear fruit, excessive sprouting of summer shoots will compete with young fruit for water and nutrients, and in severe cases cause fruit drop. So at this stage, bud removal and shoot release should be avoided as much as possible; it is recommended to postpone shoot release until after the fruit has set steadily, which can resolve this conflict. In addition, in arid regions, vigorously growing citrus trees often also send out many autumn shoots after a drought, resulting in fewer flowers the following year. In this situation, removing summer shoots can prevent early autumn shoots and prevent the occurrence of late autumn shoots.
