Pruning of Catalpa trees in spring

Catalpa will sprout new branches in spring. When the new branches grow to about 30 cm, you can choose the branches near the top, then choose the branches with strong growth and distributed on different growth tracks as the main branches, and then cut off all the other branches. In addition, during the growth period of catalpa, its trunk will sprout, which should be erased in time, otherwise it will consume too much nutrients and affect its growth. Wait until the next spring, as long as the new twigs on the main branch are screened and two new branches can be retained

Pruning of Catalpa trees in autumn

The new branches of Catalpa grow very fast. After falling leaves in late autumn, the main branches left before should be cut in a medium and short way, 40-60 cm should be reserved, and then a certain amount of outer buds should be retained. Otherwise, the crown of Catalpa will be narrow and the shading area will be small. Therefore, if you want to expand the crown, you must pay attention to retaining a certain amount of outer buds. In the late autumn of the next year, it will be medium and short cut to retain the outer buds, and then the tree shape will slowly form
