In the late winter and early spring every year, it is best to apply some organic fertilizer to the cuckoo as base fertilizer. After the rhododendron blossoms from April to May, because the plant consumes a lot of nutrients during the flowering period, the new shoots grow with the germination of leaf buds, which can be fertilized every 15 days or so. After the ambush, most of the shoots have stopped growing, at this time is the high temperature season, the physiological activity is weakened, can no longer topdressing. After autumn, the climate is getting cooler, and there is continuous autumn rain, temperature and humidity is suitable for cuckoo growth, at this time can do the last fertilizer, generally not suitable for fertilization after winter.

(5) pruning

Pruning is an important measure in daily maintenance and management, which can regulate the growth and development and make the growth exuberant. Daily pruning needs to cut off a small number of diseased branches and weak old branches, combined with the crown shape to cut off some overdense branches to increase ventilation and light, which is beneficial to plant growth.

(7) layout

Potted plants should not be placed on the ground, but should be placed on flower racks or inverted flowerpots, with shade nets or curtains hanging on them, and should be maintained.
