2. Pruning of aging branches: After kumquat enters the peak of fruiting, the aging branches outside the crown can be cut off from the base to restore the tree shape.
3. Pruning of green branches: The new branches of kumquat in the full fruit period are generally not long. Except for the long branches, some of them grow 2 ~ 3 branches at the same position at the top, with different lengths. For this kind of branches at the same level, we can use the method of removing the strong and retaining the weak, and delete some of them. Soft branches that have not reached lignification in winter can be cut off from the base.
4. Pruning of long branches: How long the long branches of kumquat are on the backbone branches, which can reach 1 m or more, with thorns. Long branches are often exposed in the middle and lower parts, and the top of branches at 1/3 often germinates into broom branches, which not only disturbs the tree shape, but also covers other branches. Long branches should be cut off from the base, except for the part that must be reserved to supplement the crown vacancy, it is best to erase them in time when the buds or branches are young, so as not to consume nutrients.
5. Pruning of fruiting branches: The fruiting branches of kumquat are still green and robust because of the developed conducting tissues. Because the branches are short, there is no need for short pruning, and dense weak branches can be thinned out.
6. Trim dead branches: Such branches should be thinned from the base. Dense transverse branches are thinly cut around the branches, and those with vacancies can be appropriately retracted.
