1. Temperature: Rhododendron Rhododendron can grow normally in a cool environment without being affected. Because of its strong cold resistance, Rhododendron can grow in an environment of minus five degrees in winter. Therefore, because of this nature, it can spend the winter outdoors when breeding in the south, but it is not suitable for outdoor breeding in the north. The normal growth temperature should be between 15 and 28 degrees.
2. Watering: the roots of Rhododendron are very sensitive to water, and the soil that is too dry and too wet will not grow well, so the watering amount should be controlled during the growth period. In summer, the demand for water is relatively high, and the watering can be done frequently. After autumn, the watering should be reduced gradually, and the watering should be controlled even more in winter.
3. Light: it needs to provide enough warm sunshine. If it is cultured in dark environment for a long time, the number of flowers will be limited. At the same time, strong light also needs to be avoided, especially if the seedlings are exposed to strong light, they will wither.
4. Fertilization: fertile soil is more conducive to growth. However, for fertilizer it does not have too high requirements, in the growth period can be fertilized every 20 days, in the flowering period will stop fertilizing, until after flowering continue to supplement nutrition.
1. Propagation: cutting and sowing are the main modes of propagation. Cutting is best carried out from June to July. Select branches with a length of about 12 cm and three leaves with oil. Then cutting can be carried out. Sowing can be carried out in April, when the temperature is suitable for seed germination.
2. Pruning: the Rhododendron needs to be pruned after flowering. While cutting off the residual flowers, it also needs to cut off some withered branches and leaves at the bottom of the plant. After clearing these useless branches and leaves, it can increase the ventilation.
1. Disease: yellowing disease will occur, which will cause the plant branches and leaves to turn yellow and lose luster. It can be improved by applying fertilizer or controlled by using some chemicals.
2. Insect damage: scale insects will occur, which can be controlled by spraying Omethoate solution.
1. Toxicity: no poison, it can be widely planted in the garden.
