In which month does the azalea bloom and what color is it?

Azalea is also called azalea. There are many varieties of azalea in nature, including spring azalea and summer azalea. Spring azalea blooms from April to May, and summer azalea blooms from July to August. But it also depends on the origin. The flowering time varies greatly in different regions. Artificial breeding depends on the breeding conditions, and the flowering time can also be controlled. The flowering period can last for more than one month.

The colors of azaleas include: red, purple, blue, green, yellow, white, pink, etc.

Is azalea harmful to the human body?

Placing azaleas indoors is harmful to the human body. Azaleas of various colors contain different toxins. For example, the plants and flowers of yellow azaleas contain strong toxins, which can cause poisoning if people come into contact with them; the flowers of white azaleas contain tetracyclic diterpenoid toxins, which can cause vomiting, breathing difficulties, numbness of the limbs, and other poisoning symptoms if people come into contact with them.

Rhododendron has luxuriant leaves, beautiful and varied appearance, strong germination ability, tolerance to pruning, and unique root piles, making it an excellent bonsai material. In the garden, it is best planted in clumps or patches at the edge of the forest, by the stream, by the pool, and by the rocks, or it can be planted scattered under sparse forests.

Rhododendrons are also good materials for flower hedges, and hairy rhododendrons can be cultivated into various shapes through pruning. The Rhododendron Specialty Garden is very unique.

Even though azaleas always give people a lively and bustling feeling when they are in bloom during the flowering season, their dark green leaves are also suitable for planting in the garden as a low wall or barrier when they are not in bloom.

How to fertilize azalea

1. Base fertilizer

Basal fertilizer refers to the fertilizer that is sandwiched in the potting soil during the process of repotting and soil change. The fertilizer used can be a slow-release compound fertilizer or a well-rotted organic fertilizer. The fertilizer is mainly used to improve the soil and slowly supply nutrients. You can use well-rotted bone meal and some slow-release compound fertilizers and mix them into the potting soil.

The base fertilizer used should not come into contact with the roots of the azalea. That is to say, after the fertilizer is added, a layer of soil should be placed on it, and then the azalea should be planted to avoid fertilizer damage.

2. Topdressing

Top dressing is the fertilizer applied during the growth period of azalea. It is usually applied after flowering, before new buds emerge, and during the differentiation of flower buds. When it has finished flowering, top dressing can be applied in time to promote the sprouting of new buds and enter a new growth period.

When applying topdressing, quick-acting fertilizers should be used. The fertilizers can be relatively simple, and the fertilizer effect should be fast. In the cool autumn season, phosphorus and potassium fertilizers need to be applied, and the application of nitrogen fertilizers should be controlled to promote the differentiation of flower buds.

3. Fertilization principles

Rhododendrons need to be fertilized frequently with thin fertilizers, and the concentration of the fertilizer should not be too high. We can add one tenth of the fertilizer to the water every time we water it.
