Temperature: during the maintenance period, provide a warm environment of 15-20℃ for Rhododendron. Lighting: During the growing and flowering period, more lighting should be given. In the summer with strong light, you should pay attention to shading to avoid sunburn. Watering: It likes humidity, but it can't grow in the soil with stagnant water. Therefore, water it properly at ordinary times to keep its flower soil slightly wet. Fertilization: topdressing 1-2 times a month is enough in the growing season, and phosphate fertilizer should be topdressing before and after flowering.

I. Maintenance methods

1, temperature: azaleas in high months like to be cool, specifically, it is between 15 and 20 degrees. It is a heat-resistant variety, and it is best to adjust it when it is higher than 30 degrees, otherwise the leaves will be burned and the flowering will be affected. In addition, the temperature in winter should be above 10 degrees.

2, lighting: Rhododendron likes light, but is extremely afraid of strong light. Therefore, in summer and autumn, if you encounter too strong light, you should try to block it, or there is a big tree next to it. But when flowering, don't be too dark.

Watering: Rhododendron likes to be wet. If it is cultivated in a place with little rain, it is necessary to replenish water to the substrate in time and spray water frequently. Of course, it should not be too waterlogged, and water should be avoided.

4, fertilization: Rhododendron is afraid of hypertrophy, pay attention to dilution when fertilizing. The frequency of fertilization does not need too much, usually once or twice a month. Fertilization before and after flowering is more important, especially phosphate fertilizer.

Second, feeding skills

1. Propagation: Cutting is the most commonly used propagation method. May and June are more suitable. Select semi-lignified, as new as possible, branches with a length of 5-8 cm as materials. It's best to cut off some leaves before cutting. In addition, shading after cutting and maintaining temperature and humidity are also important.

2. Pruning: Rhododendron is very resistant to pruning, which is a very important step. Picking the heart before flowering can promote better flowering in the later stage. At the end of autumn, that is, when it is fast dormant, it is necessary to repair all kinds of bad branches such as dead branches and long branches.

Third, the problem diagnosis and treatment

1, disease: May-August, the common disease is "brown spot disease", triadimefon can be sprayed once every ten days. There will also be "currency diseases", which can be prevented and treated with copper sulfate.

2. Pests: The main category is "aphids", which can also cause plants to be infected with other diseases and need to be prevented in time. It can be controlled by carbofuran.

Four. Other issues

1, toxicity: Rhododendron alopecuroides is nontoxic.

2. Can I keep it at home? Its main value is ornamental, which is very suitable for keeping at home.
