1. Temperature: Rhododendron is suitable for growing in a cool environment. The fastest growing temperature is between 15 and 20 degrees. Too high temperature is not conducive to its growth. If you want to delay flowering, you can reduce the temperature to 2 to 4 degrees when the flower buds appear, and keep it in a low temperature state. This will have a very obvious effect.
2. Watering: a large amount of water is needed during the growth period in summer, and the water will evaporate quickly in high temperature weather. At this time, water needs to be supplemented in time, and the humidity in the air should also reach the standard. The water evaporated from the leaves can be supplemented by spraying. The soil should be kept wet all the time, and enough water will have a good growth.
3. Light: the normal growth needs to provide sufficient and warm sunshine. It will be better if the flowers are full of light and the color will be more bright. However, they can not be directly placed outside to receive strong light, otherwise they will be sunburned and will face wilting. In summer, if you breed outdoors, you can use sunshade cloth to shade it, to ensure normal growth.
4. Fertilization: for the growth of Rhododendron, it is necessary to keep the soil fertile. However, it is necessary to apply thin fertilizer frequently. Do not apply too much fertilizer every time. It can be done many times. During flowering, you can apply one time of phosphate fertilizer, and after flowering, you can apply one or two times of nitrogen phosphorus compound fertilizer.
1. Propagation: cutting is the main mode of propagation. The best time is from May to June every year. Select about 5cm to 8cm branches to cut. The temperature should also be kept between 20c and 25C. Spray water mist frequently to promote growth..
2. Pruning: the Rhododendron should be pruned properly during the growth period, so as to ensure the germination of new branches, cut off some residual flowers in time, which is conducive to the next flowering, and also reduce nutrient loss.
1. Disease: leaf swelling disease will occur, which will lead to uneven branches and leaves of plants. Bordeaux solution can be used to control
2. Insect damage: the crown net bug will appear, the larva and the adult will affect the growth and development of Rhododendron, at the same time, they will leave some unknown liquid on the branches and leaves, which can be sprayed with Omethoate solution for control.
1. Toxicity: no poison, it is a kind of drug with good effect.
2. Can you keep it at home? Yes, it has high ornamental flowers, but in summer, you should open the window for ventilation.
