The leaves of oleander planted on the branches have the characteristics of trifoliate growth, and at the same time, they are typical trident plants, that is, every time they are pruned, three new branches will grow on the stem nodes. The characteristics of this branch of oleander can be used for pruning and shaping to form a crown with three branches and nine tops. The specific pruning methods are as follows: from young plants, when the trunk grows to 50 ~ 60 cm high, topping will be carried out, and soon three main branches will grow on the trunk; When the main branch grows to about 20 cm, each branch is left about 20 cm for topping to promote it to sprout new branches again. After such pruning, a beautiful "three branches and nine tops" crown was formed.
