The Rhododendron just bought home is not very suitable for the home environment, especially in the dry home environment, when the original flower bud develops normally, the flower bud will stop growing in the dry environment. Then there will be drying, shrinking and falling buds. If the environment is not improved and the humidity is increased, the plant will wither. How can it bloom?
When the Rhododendron is budding, it needs to be watered once a day, 2-3 times a day, and often to the surrounding ground to increase the air humidity. In rainy days, you can contact with rain water to irrigate, and the plants will grow better and blossom faster.
In winter, Rhododendron is kept indoors. The temperature in most families is between 15 ℃ and 20 ℃, so it is easy to sprout new buds. However, the new buds will be next to the flower buds. In the spring of next year, the flower buds will continue to grow and compete with the flower buds for nutrients. If the nutrients of the flower buds are insufficient, they will gradually shrink and be difficult to bloom.
In winter, try to control the environmental temperature of Rhododendron at about 10 ℃, not too high, or wipe the buds in time in spring to hinder the growth of flower buds and avoid competing with them for nutrients.
Rhododendron only has long leaves and does not bloom. It can be understood that it has excessive nutrition, but new branches do not bloom. Too much fertilizer and water, especially too much nitrogen fertilizer, all nutrients are concentrated in the leaves, nutrient distribution is uneven, and too much water will affect the overall growth of the plant.
Before flowering (March to April), do not apply nitrogen fertilizer, only increase P and K fertilizer to promote flower bud differentiation. Cut off the long branches in time, reduce the branches and leaves of the crown, and enhance the transparency. After spring, control watering to make the basin soil moist and the basin surface dry.
