soil management
Rhododendron cornutum likes loose and fertile weak acid soil. If the soil is alkaline, it will easily lead to poor growth of Rhododendron cornutum, and even lead to iron deficiency and chlorosis. The soil should ensure good air permeability and drainage, and the pot soil should be disinfected before planting to prevent the occurrence of pests and diseases.
Lighting management
Rhododendron antlers don't like direct glare, especially in summer, even the sun rays in the evening should be blocked. It is best to put plants in a semi-shady place, which can not only shade the sun, but also scatter sunlight.
water management
When cultivating Rhododendron cornutum, attention should be paid to controlling watering. Too much or too little watering is not conducive to its growth. If it is too dry, it will easily cause the leaves of plants to wither and yellow, and the petals will be dim. Too much watering can easily lead to premature withering of flowers. During the flowering period of azaleas, be careful not to let the water drench the flowers when watering, and avoid the plants from getting wet at ordinary times. It is best to water it in the morning and evening, and be careful not to accumulate water in the basin, otherwise it will easily rot the roots. It is best to use natural water with a little rice vinegar instead of tap water all the time.
Temperature management
Rhododendron cornutum is not cold-resistant, so we should pay attention to heat preservation in winter, and the temperature should not be lower than 8℃. It is best to move it indoors for culture. It is hot and dry in summer, so you should always spray water on the leaves to keep them moist, and do proper shading treatment to prevent the leaves from being sunburned.
Eliminate pests and diseases
Common diseases and insect pests of Rhododendron cornutum include leaf spot, leaf swelling, aphid, sawfly and so on. This will greatly harm the growth and development of Rhododendron cornutum. Daily maintenance should pay attention to sterilization and pest control. Generally, insect pests can be treated with drugs or controlled manually. The disease needs to be cut off in time to prevent the spread of germs, and then sprayed with chemicals for sterilization. Pests and diseases mostly occur in hot and humid seasons, so we should pay attention to ensure the ventilation of soil and environment to prevent the breeding of germs.
Dressing and shaping
The residual and diseased flowers of Rhododendron cornutum should be cut off in time to prevent them from falling into the pot soil and breeding bacteria. When the amount of flowers reaches 80%, the residual flowers should be trimmed in time. The pruning of Rhododendron cornutum should be completed before the full flowering period, otherwise it will affect its flowering in the next year.
