1. Soil requirements

Rhododendron ovale needs to be cultivated in suitable soil when it grows. It is usually the most appropriate to choose some acidic soil for breeding. However, the soil in the north is very alkaline, so if you want to cultivate it, the basin soil needs to be prepared to use

2. Management of fertilizer and water

The root system of Rhododendron ovale is very slender, so the requirements for fertilizer concentration and water quality are very strict. When applying fertilizer to it, it must be appropriate. Before flowering in spring, in order to make its branches, leaves and buds grow better, phosphate fertilizer can be applied to it once a month. After flowering, a mixture of nitrogen fertilizer can be applied once or twice. Wait until September to October to apply phosphate fertilizer once or twice. During growth and flowering, there are many requirements for fertilizer and water, but there will be less requirements when dormant in winter and summer, so we must control and prevent rotten roots at this time. In addition, the weather in the north is relatively dry, and should be watered or sprayed in time, so that humidity can be increased. p>

3. Regular plastic surgery

In order to make its plants bloom faster, we should pay attention to pruning them at ordinary times. Generally, the method of picking the heart is used to promote the germination of its branches. For those flowers that are relatively compact and affect the flower shape, they can be thinned in advance, which can not only make its flower color more bright, but also make it bloom and grow more smoothly in the next year. Its germination ability is relatively strong, so sometimes appropriate pruning is also to maintain its beautiful appearance, so that its ornamental and commercial nature will be maintained all the time

4. Flowering control

It usually carries out flower bud differentiation in autumn. At this time, we need to artificially control the flowering period by freezing or raising the temperature. If you want it to blossom in advance, you can move it to the greenhouse for cultivation. The temperature is 20 to 25 degrees, and you should often spray water on the branches and leaves. If you want to delay, let it stay at a low temperature. The temperature is 2 to 4 degrees. When the basin soil is dry, pour some water, move outside in summer and bloom in two weeks
