When we maintain it at ordinary times, we all hope that it will bloom soon, so that we can appreciate its beauty as soon as possible. Generally, the method of coring is used to make it send out new branches quickly. Some flower branches may have dense buds. In order not to affect the beauty of flowers, bud thinning can be carried out appropriately. In this way, the quality and quantity of flowers will be greatly improved, which will also be of great help to its flowering in the coming year.

Rhododendron rubrum has strong germination ability. If there are too many branches, the growth of plants will be seriously affected and the ornamental effect will be greatly reduced. So at this time, we need to do some plastic trimming to change this phenomenon. Pruning branches doesn't mean you can do it at any time. Generally, it is carried out in spring or autumn, and some diseased branches, dead branches and some forked branches on its plants are cut off one by one, so that nutrient consumption can be well avoided and the flowers of the plants are bright and full.

2. Flowering control

The red rhododendron usually starts flower bud differentiation in autumn, and we can artificially control the flowering period by some refrigeration and heating treatments at this time.

If you want to bloom in advance, you can move it to the greenhouse for maintenance, keep the temperature at 20 to 25 degrees, and often spray water on its branches and leaves to keep the humidity above half, so that it can bloom basically in one month.

If you want to welcome the blooming of azaleas later, let those plants that have formed flower buds stay in a low temperature environment for a long time. As long as the temperature is kept between 2-4 degrees, when the soil looks dry, you can pour some water on it. In summer and autumn, it can be moved outdoors, and basically it will bloom after 2 weeks.
