How to cultivate Rhododendron yunjinensis

1. Maintenance methods

1. Temperature: It does not have high temperature requirements. As long as it is in a warm environment, it will grow vigorously. It can be kept between 15 and 30 degrees, try not to be too high. In winter, its cold resistance is not very good, so if you grow it in very cold places in the north, you need to protect it from the cold.

2. Light: Rhododendron yunjinensis likes light, but it can also tolerate shade to a certain extent. During the normal growing season and flowering time, it is sufficient to provide diffuse light. When there is strong light, provide some shade to prevent its leaves and flowers from getting burned.

3. Watering: Generally speaking, Rhododendron yunjinensis likes moisture, but it should not be watered too much in summer and winter. Too much watering in the summer can cause root rot, while too much watering in the winter can cause frostbite. It needs to be kept moist during the spring and autumn when it grows most vigorously.

1. Reproduction: You can use the cutting method, which is relatively simple and easy to survive. Choose semi-lignified branches that are five to eight centimeters long, and cut off the leaves on the lower half, leaving only two or three leaves. You can use some rooting powder first. After being inserted into the soil, shade should be provided. After its growth state stabilizes, it can be maintained normally.

2. Repotting: If it is potted planting, the soil needs to be changed once a year. The time for repotting can be after flowering each year. You can choose leaf mold, sandy soil, etc. When changing the pot, you can repair it at the same time. After repotting, you need to ensure that the environmental conditions are suitable, without strong light, and ensuring humidity, etc.

3. Problem diagnosis and treatment

1. Diseases: The two main diseases are leaf blight and rust. The former can be controlled with Class A thiophanate, and the latter can be controlled with triadimefon.

2. Pests: Common types of pests include "army bugs", "weevils", etc. There are a large number of them and they reproduce quickly. They can be controlled with Kung Fu emulsion.
