Picking: Also known as pinching and topping, it is to cut off or cut off the top of the main stem or side branch of a flower plant by hand, so as to break the top advantage of the plant, promote the germination of axillary buds at its lower part, inhibit the overgrowth of branches, and promote the plants to branch more, form multi-flowered heads and have beautiful plant shapes.

Hairdressing: Large flowers, such as rubber trees, Millennium trees, Liriodendron chinense, and pollen leaves, are too high to be cultivated indoors and need pruning or hairdressing. Usually, before the new branches sprout in spring, all the upper parts of the plants are cut off, that is, plastering. The height of the trunk when plastering depends on the kind of flowers.

Branch thinning: including thinning branches, leaves, buds, flowers and adventitious buds. When flowers and plants grow too vigorously, resulting in too dense branches and leaves, some branches should be thinned or too dense leaves should be removed in time to improve ventilation and light transmission conditions, so that flowers can grow stronger and flowers and fruits can be more colorful. Potted flowers should also be pruned frequently for dead branches, dead leaves and leaves damaged by pests and diseases, so that the plant shape is neat and beautiful. Leaf-watching flower varieties with stripes and leaves are formed by germination of green plants. The growth of green branches is stronger than that of mottled and mosaic branches, so it is necessary to prune them in time to prevent green branches and leaves from being covered with mottled and mosaic branches and maintain the characteristics of the original varieties. It should be noted that conifers such as five-needle pine are not suitable for defoliation.
