From the second year of planting, oleander plants can be shaped. In order to make oleander blossom again, it is necessary to pick the heart properly after each flowering, which can make the flowering times reach 3~4 times a year.

Pruning method

In order to make the plant shape of oleander plump and blossom luxuriantly, this goal can also be achieved by short-term cultivation and pruning of oleander plants. When the height of the newly cultivated trunk reaches 40 cm, cut off the top from the node with full axillary buds at 20~30 cm. After half a month, new buds will grow and develop into the first layer of three branches that year. After autumn or early spring, according to the growth of new branches, the pruning height is determined, and the secondary pruning height is about 70cm. After three times of shaping and pruning, the crown of oleander can be in the shape of "three forks and nine tops", with short, thick and plump plant type and good ornamental effect. The future pruning work is mainly to cut off the weak branches and old branches in the hole, so that the branches are lush and full of flowers. When transforming the old oleander pile, we should choose strong main branches, cut off sprouting branches, and develop and finalize the design in the second year after plastic surgery. After pruning, the crown of oleander is full and mushroom-shaped.
