Cultivation method of Rhododendron tubulosa

1. Maintenance methods

1. Temperature: Rhododendron tubulosa prefers cool weather because it is generally distributed in high altitude areas. Specifically, it can be between fifteen and twenty degrees. It does not have a strong tolerance to high temperatures, so it needs to be adjusted in summer, and try not to exceed 30 degrees. It has good cold tolerance.

2. Light: Rhododendron tubulosa has certain requirements for sunlight. Especially before the flowering period, if it is too dark, flower buds will not form. But too strong light should also be avoided. Especially in summer, a little diffuse light is enough, and you can choose a time of the day when the light is not so strong to let it receive light.

3. Watering: Rhododendron crestedum likes moisture, but too much waterlogging will cause its roots to rot. In the north, the climate may be relatively dry, so you can water more and maintain appropriate air humidity. But when the rainy season comes, the main task is drainage.

4. Fertilization: This is a very important step for it. Fertilization is of great significance, especially during the flowering period. The main fertilizer used is phosphorus fertilizer, which should be applied before and after flowering.

2. Breeding techniques

1. Reproduction: You can use the cutting method, which is the most common method. May or June is best. Choose semi-woody, sturdy branches, with a length of five to eight centimeters. After you cut it, you can remove the lower half of the leaves. It will be more effective if you treat it with rooting powder first. After cuttings, the most suitable temperature is between 20 and 25 degrees, and spray frequently.

2. Pruning: First of all, in order to make it bloom better, it is best to pinch the top of the plant. In addition, since the germination ability of Rhododendron tubulosa is very strong, its branches and leaves need to be pruned to a certain extent, such as some dense and long branches.

3. Problem diagnosis and treatment

1. Diseases: There are many types, such as "leaf swelling disease". After discovering diseased leaves, cut them off in time and then apply mancozeb solution. There will also be "leaf spot disease", which can be treated with oxycarboxin.

2. Pests: "Aphids" and "mites" are quite common and can be controlled with furadan.

IV. Other issues

1. Toxicity: It belongs to a type of rhododendron, which is non-toxic.

2. Can it be grown at home?: It is also a relatively good ornamental plant. It is quite common to place it as a potted plant at home for viewing.
