The invention relates to a planting method of red orange. The planting method includes: (1), selecting and preparing land; (2), pressing branches for propagation; (3), digging planting pits; (4), planting; (5), managing young trees; (6), managing fruiting trees; (7), preventing and controlling disease and pest; (8), harvesting at proper time. A position, where epidermis is removed, of each branch is wrapped by mud, bone powder and a rooting agent in the mud are conducive to branch rooting, and rice vinegar plays a role in sterilizing and disinfecting, so that red orange seedlings maintain excellent performance that mother plants have; iron wires are used to bind trunks of the young trees, so that transverse growth of the red orange trees is facilitated, cultivation time of the red orange trees is reduced, and fruit yield of the red orange trees is increased; nitrogen fertilizer and phosphorus fertilizer for promoting shooting and sodium humate are proper in proportion, so that branch shoots are promoted to grow transversely; nitrogen fertilizer and phosphorus fertilizer for strengthening shoots and sodium humate are proper in proportion, so that the branch shoots can be promoted to grow more thickly and strongly; artificial pollination is performed after flower thinning, so that fruit setting rate of the red orange is increased.
