When you see this name, you may involuntarily think that it is azalea. In fact, it is not the case. There is still a big difference between the two. The flowers of Rhododendron ovata are very unique, just like the funnel shape we used to use in our home, but the color of the flowers makes you linger after seeing them, and you can’t help but want to capture them with a camera. This most touching moment. Therefore, the visual shock it brings to people is extraordinary. Of course, you must be careful when raising it. Let’s take a look.

1. Soil requirements

When Rhododendron ovata grows, it needs to be cultivated with suitable soil. Usually it is most suitable to choose some acidic soil for cultivation. However, the soil in the northern region is very alkaline, so if you want to cultivate it, the potting soil needs to be prepared to a certain extent before it can be used.

2. Management of fertilizer and water

The root system of Rhododendron ovata is very slender, so the requirements for fertilizer concentration and water quality are very strict. When applying fertilizer to it, be sure to use the right amount. Before flowering in spring, you can apply phosphorus fertilizer to it once a month to make its branches, leaves and flower buds grow better. After flowering, you can apply a nitrogen fertilizer mixture 1 or 2 times. You can apply phosphate fertilizer once or twice from September to October. When growing and blooming, it requires a lot of fertilizer and water, but when it goes dormant in winter and summer, it requires less, so it is necessary to control and prevent root rot at this time. In addition, the weather in the north is relatively dry, so you should water or spray it in time to increase the humidity.

3. Regular plastic surgery

For Let its plants bloom faster, so you should pay attention to pruning them regularly. Generally, the method of topping is used to promote the germination of its branches. For those whose flowers are relatively compact and affect the flower shape, the buds can be thinned in advance. This will not only make the flowers bloom more vividly, but also allow them to bloom next time. Annual flowering and growth are smoother. Its germination ability is relatively strong, so sometimes proper pruning is done to maintain its beautiful appearance, so that its ornamental and commercial properties will be maintained.

4. Flowering period control

It usually differentiates its flower buds in autumn. At this time, we need to artificially control the flowering period by refrigeration or raising the temperature. If you want it to bloom early, you can move it to a greenhouse and cultivate it at a temperature of 20 to 25 degrees, and spray water on the branches and leaves frequently. If you want to delay it, just let it stay in a low temperature state, the temperature is 2 to 4 degrees. When the pot soil is dry, water it some, move it outside in summer, and it will bloom in 2 weeks.
