Why can't we keep azaleas at home?
Today, I will introduce to you why we can't keep azaleas at home and the precautions for keeping azaleas as houseplants. Let's learn about it together.
Is it suitable to keep azaleas indoors? It is not difficult nor easy to keep azaleas well. Most azaleas prefer a ventilated environment, so it is actually not very suitable to grow them indoors. Then, where is it generally suitable to keep azaleas? Let's let the editor of Aipet.net give a detailed introduction.
Is it suitable to keep azaleas indoors?
In fact, azaleas are not suitable for indoor cultivation because although they like shade, they are most afraid of poor ventilation. It is not suitable to keep any plants in a residential room. From the perspective of photosynthesis in plants, they do not receive much sunlight and can only release a small amount of oxygen, while at night they release a large amount of carbon dioxide. In other words, their benefits cannot outweigh their drawbacks.
Azaleas can be exposed to the sun, but not constantly. Azaleas are neutral flowers that prefer a warm, semi-shaded, cool, ventilated, and humid environment. They require loose, fertile, humus-rich acidic (loess) soil with a pH value between 5.5 and 6.5. Avoid using alkaline or sticky soil. The suitable growth temperature is between 12°C and 25°C. In summer, they need shade and sun protection, and in winter, they need frost prevention and warmth. It's best to move them indoors, especially the more delicate azaleas like the Western azaleas, which require more attention in terms of care.
Why are azaleas not suitable for indoor cultivation?
It is known that the biological amplification effect of azalea leaves reduces the concentration of toluene in indoor air. This has a very positive practical significance in the field of indoor air pollution and has a bright application prospect.
Although azaleas can purify the air, they are not cold-resistant. They should be moved indoors during the Cold Dew and Frost Descent periods and placed in a sunny area. In other seasons, it's best to keep them outdoors with proper shading to prevent "cold." And at the beginning of winter, attention should be paid to opening windows for ventilation. If kept in the shade for a long time, it is prone to dropping buds.
Where is it suitable to keep azaleas?
1. For cultivating Western azaleas, both indoor and outdoor environments are needed: indoors for winter frost protection (not lower than -2°C to -3°C), and outdoors to survive the hot summer. In the Jiangnan region, they are kept outdoors from mid-April to early November, requiring natural shade from deciduous trees or artificial shade structures to create a semi-shaded and cool growing environment. The ground should have a drainage slope, and the flower pots should be placed on shelves.
2. Pot selection: In production, ventilated and inexpensive clay pots are used. Large-scale production can also use hard plastic pots, which are aesthetically pleasing and convenient for transportation. Both domestic and international large enterprises use them. Azalea roots are shallow and expand slowly, so it's best to use small pots to avoid uncontrolled watering, which is not conducive to growth.
3. Soil: Commonly used is black mountain soil, also known as orchid soil, or peat soil, Huangshan soil, decomposed leaf soil, pine needle soil, and decomposed sawdust, with a pH range of 5 to 6.5. These soils have good permeability and drainage and are rich in humus.
4. Potting: It is usually done in spring when moving out of the room or in autumn when moving into the room. A layer of coarse soil for drainage is placed at the bottom of the pot. After potting, place it in the shade for several days before moving it to the appropriate location. Young seedlings need to be repotted more frequently, every 1 to 2 years, and after 10 years, it can be done every 3 to 5 years. For older plants, repotting is not necessary unless there are problems.
