This kind of flower can be directly planted in the soil or potted. But it has requirements for soil, because of its own nature, it is particularly fond of acid soil, and the soil must be soft, if it is very hard, they will not grow well. Drainage also needs to be in place, there will be water on its growth will also have an impact. In addition, we should use the soil containing humus. It's better to have sand, sawdust and cake fertilizer in the soil
If we want to use flowerpots for planting, we need to pay attention to that the roots of plants need to leave some original soil during the transfer process. In addition, we should be careful not to hurt the root. If the plant is quite lush, we should trim the leaves properly, cover the drain hole at the bottom during the basin loading process, and then use coarse soil as the drainage layer. After the middle part is filled with soil, the plant can be moved in, and pay attention to the depth and water consumption during the moving process.
Watering needs careful attention, because Rhododendron is very fragile, it can not be too dry or too wet, if it is in a dormant state, it can reduce the amount of water, or even not watering. When the temperature is high, the frequency of watering should be increased. Between March and June, when the plants are growing in large quantities, we need to water more according to the actual situation. In the hot summer, we should water every day, and after autumn, the number of watering can be greatly reduced.
Fertilization is very important. We need to use thin fertilizers. Some basic fertilizers have a long effect, such as bone meal and cake fertilizer, while top dressing requires quick acting fertilizers, such as organic fertilizers containing elements such as N and P. When spring comes, potash fertilizer should be applied every month before flowering, but when autumn comes, it's fertilizer containing phosphorus, no fertilizer is needed in winter
