Why doesn't azalea bloom?

1. The air is too dry

The azaleas that have just been bought home are not yet well adapted to the home environment, especially the dry environment. Even if the original flower buds develop normally, they will stop growing in a dry environment. Then the plants will begin to dry up, shrink and fall off. If the environment is not improved and the humidity is not increased, the plants will wither and die. How can they bloom?

When azalea buds appear, they need to be watered once a day, sprayed 2 to 3 times, and the surrounding ground should be sprinkled with water frequently to increase the air humidity. On rainy days, you can collect some rain water for watering, the plants will grow better and bloom faster.

2. Sprouting new buds and pulling out dead flowers

Rhododendrons should be kept indoors in winter. The indoor temperature in most households is between 15 and 20 degrees Celsius, so it is easy for new buds to sprout. The new buds often grow next to the flower buds. In the spring of the following year, the flower buds continue to grow and compete with the flower buds for nutrients. If the flower buds lack nutrients, they will slowly wither and become difficult to bloom.

In winter, try to control the ambient temperature of azalea at around 10℃, not too high, or remove the buds in time in spring to hinder the growth of flower buds and avoid them competing with flower buds for nutrients.

Three: Too much fertilizer and water

The fact that azalea only grows leaves but no flowers can be understood as an excess of nutrients, with new branches growing but no flowers blooming. Too much fertilizer and water, especially too much nitrogen fertilizer, will concentrate all the nutrients on the leaves, resulting in uneven nutrient distribution. Excessive watering will affect the overall growth of the plant.

Before flowering (March to April), do not apply nitrogen fertilizer, only apply phosphorus and potassium fertilizers to promote the differentiation of flower buds. Cut off the overgrown branches in time to reduce the branches and leaves in the crown and enhance light transmittance. Control watering after spring to keep the soil in the pot moist and the surface of the pot dry.
