How to care for azaleas indoors in summer
Core introduction: How to care for azaleas indoors in summer and tips for growing azaleas, followed by detailed content sharing.
In summer, potted azaleas should be fertilized with only "2 types" for deep leaf color and continuous bud formation.
Azaleas bloom beautifully and prefer a cool climate. High temperatures will lead to slow growth. Their vigorous growth periods are in spring and autumn, but they also grow slowly in summer, which is the most crucial season and the key to successful care.
After entering summer, azaleas will grow slowly. The first thing we need to do is to place them in a place with moderate sunlight, such as under a flower shelf with scattered light, or under a big tree. Due to high temperatures, the activity of azalea roots decreases, and their absorption function weakens. To ensure good growth, we must ensure good ventilation and adequate water. The watering principle is to water thoroughly when the surface of the potting soil is dry to a depth of one or two centimeters. If you are growing them indoors, make sure the bottom does not accumulate water, as this can easily lead to root rot.
Should we fertilize them? Fertilization should not stop. When growing azaleas in summer, I usually only choose two types of fertilizers. The first type is to supplement acidic substances, and the second type is to promote root development, hardening of branches, and formation of flower buds at the top, which is mainly composed of phosphorus and potassium elements. The fertilizer to supplement soil acidity is ferrous sulfate, as azaleas are flowers from the south and cannot lack acidic substances. In alkaline soil, their leaves will be green in the veins and yellow elsewhere, especially noticeable in new leaves. Therefore, it is necessary to supplement ferrous sulfate at least once a month. The dilution ratio of ferrous sulfate in summer is 1:1000 or more. After diluting it with water and thoroughly watering the potting soil, wait for about half an hour to allow the roots to absorb the ferrous sulfate components, and then water thoroughly again to wash away any excess ferrous sulfate that has not been absorbed.
The second type of fertilizer is potassium dihydrogen phosphate. I usually choose one with a focus on phosphorus and potassium elements, using it twice a month. Phosphorus and potassium fertilizers can promote root development, making them thicker and the tender branches gradually harder and older. In the hot and humid summer, the top of the plant will gradually close and differentiate into flower buds. If you continue to fertilize at this frequency and get these two types of fertilizers right, by autumn, the top of the branches will close, the tender branches will become older, and flower buds will quickly grow.

Fertilization should not be lacking. By autumn, every tender branch will grow a flower bud, which will continuously expand. When they bloom in winter, they will be very beautiful. Phosphorus and potassium fertilizers must be water-soluble and not too concentrated, with a minimum ratio of 1:1000. However, to grow azaleas well, ventilation must be good, with some scattered light and adequate water. These points should also be maintained to ensure your azaleas are full of flower buds in autumn.
