Last Updated: 2024/11/06, Dandong rhododendron likes the warm, cool and humid environment. Dandong rhododendron cultivated in southern cities must be shaded by curtains in summer, otherwise, the sun will burn the leaves and affect the growth of pregnant buds. At the same time, lay a layer of grass bags or sawdust on the ground, about 5 cm thick, sprinkled with water. Put a layer of bricks on it, and then put the flowerpot on the brick. In case of high temperature, in addition to wetting the ground, spray on the leaves of rhododendron several times a day to form a cool and humid microclimate suitable for the growth of Dandong rhododendron. Southern cities enter immediately after the end of the rainy season in Huangmei.

Southern cities enter the hot season immediately after the end of the rainy season in Huangmei. Light fertilizer can be applied in early July to facilitate bud formation. Since then, it is forbidden to apply liquid fertilizer to the basin in the hot season to prevent root damage. In order to ensure that the azaleas grow well and spend the summer safely, 0.2% potassium dihydrogen phosphate can be sprayed on the leaves once a week. In the high temperature season, diluted with 25% omethoate and water every ten days to 1000ml 15000 times, foliar spraying can control insect pests. Spraying leaves with topiramate or carbendazim every ten days is very effective in sterilization and disease treatment.
