The seedlings planted in that year can grow naturally by watering once, and watering once every 15 days according to the soil moisture. Combined with intertillage weeding, topdressing 1 ~ 2 times a year is appropriate in spring and autumn, and dilute liquid fertilizer mainly containing nitrogen is generally applied.
Holly sprouts and grows branches many times a year, which is extremely resistant to pruning. It should be pruned once in summer, and it can be pruned into a flat shape or a spherical shape or a conical shape in autumn according to different greening needs, and the branches should be properly thinned to maintain a certain crown-shaped branching state. Measures such as piling up soil to prevent cold can be taken in cold places in winter.
