Why don’t rhododendrons bloom?

There are many reasons why azaleas do not bloom. If the air is too dry, sprinkle water on the surrounding ground to increase the air humidity. If it is caused by new buds and dead flowers, the buds should be wiped in time in spring. If it is caused by too much fertilizer and water, then water and fertilize scientifically.

1: The air is too dry

The azaleas you just bought home are not very adaptable to the environment at home, especially the dry environment at home. Even if the original flower buds develop normally, the flower buds will disappear in a dry environment. will stop growing. Then there will be dryness, shrinkage, and bud drop. If the environment is not improved and the humidity is increased, the plants will wither and how can they still bloom?

When the azaleas are budding, they need to be watered once a day, sprayed 2 to 3 times, and often sprinkled with water on the surrounding ground to increase the air humidity. On rainy days, you can irrigate with some rainwater, and the plants will grow better and bloom faster.

Two: Kill the flowers after new buds appear

< p> Rhododendrons are maintained indoors in winter. The indoor temperature in most homes is between 15 and 20°C, making it easy for new shoots to germinate. The sprouted new buds are often next to the flower buds. The flower buds will continue to grow in the next spring and compete with the flower buds for nutrients. If the flower buds lack nutrients, they will slowly shrink and become difficult to bloom.

Try to control the ambient temperature of azaleas at about 10°C in winter, not too high, or wipe the buds in time in spring to hinder the growth of flower buds and prevent them from competing with the flower buds for nutrients.

Three: Too much fertilizer and water

Rhododendron only has leaves but no flowers. It can be understood that due to excessive nutrition, new branches sprout but no flowers. Too much fertilizer and water, especially too much nitrogen fertilizer, will cause all nutrients to be concentrated in the leaves, resulting in uneven distribution of nutrients, and excessive watering, which will affect the overall growth of the plant.

Before flowering (March to April), do not apply nitrogen fertilizer, only increase phosphorus and potassium fertilizers to promote the differentiation of flower buds. Cut off leggy branches in time to reduce the number of branches and leaves in the crown and enhance light transmittance. After spring, control watering so that the pot soil is moist and the pot surface is dry.
