How to breed Rhododendron pubescens

1. Maintenance methods

1. Temperature: Rhododendron hairyii prefers a cool growing environment and the temperature cannot be too high. If the temperature is too high in summer, some cooling measures need to be taken. You can spray water mist to lower the temperature of the branches and leaves so that it can grow normally outdoors.

2. Watering: It likes a moist growing environment, and the soil must be kept moist so that the flowers will be more vibrant. Otherwise, the branches and leaves will become dry and dull. At the same time, Rhododendron hairyii is also very particular about the humidity of the air and does not like a dry growing environment. If conditions permit, it is best to water it with some rainwater and natural water, so that its growth ability will be stronger.

3. Light: It likes warm light, but cannot be exposed to strong light. It is best to give it appropriate shade in summer, otherwise the newly arrived flowers will easily wither. It is a semi-shade to partial-sun plant and can accept full sunlight in spring and winter with mild sunlight.

4. Fertilization: Before flowering, you can apply phosphorus fertilizer once a month, and after flowering, continue to add nitrogen-phosphorus compound fertilizer several times. More fertilizer will be needed during the flowering period. The plants begin to dormant in winter, so you should stop fertilizing them and let them spend the winter normally.

2. Breeding techniques

1. Reproduction: Cutting is the main method, which can be carried out from May to June. Cut about eight centimeters of tender branches and cut them into the soil. Keep the temperature above 20 degrees and below 25 degrees. Pay attention to shade it to prevent it from withering in the sun, and then wait for it to germinate before transplanting.

2. Pruning: It has a very strong growth ability and a very strong sprouting ability, so it needs to be pruned from time to time, cutting off some useless branches, reducing the loss of nutrients in the side branches, and cleaning up any yellowing or withered leaves at any time to maximize its ornamental effect.

3. Problem diagnosis and treatment

1. Disease: Leaf spot disease will occur. This disease will cause some spots to appear on the branches and leaves of the plant. In severe cases, all the plants will die, so it is necessary to spray mancozeb solution to control it.

2. Pests: Aphids will occur and bite the flowers, reducing their ornamental value. This is the main hazard. You can spray a dichlorodiphenyltrichloroethane solution to prevent and control it, which can have a good effect.
