1. Choose the right soil.
Soil is an essential element for plant growth, of course, some hydroponic plants are discharged. But azaleas should be raised in the soil. Rhododendron should be cultivated in soil suitable for its growth. Rhododendron is suitable for loose, breathable, slightly acidic and rich in mechanism.
2. Sprinkle water moderately.
Another important factor of growth is water. How to raise azalea and how to sprinkle water is a crucial step. I believe that anyone who raises azalea knows that the roots of azalea are particularly thin and really comparable to hair. So when we sprinkle water, we must be careful not to overdo it, just the right amount. Generally, if you spray water, you should choose to water it in the morning or at night, just avoid noon.
3, thin Qin Shi Fei
Like most plants, azaleas can't grow without nutrients brought by fertilizers. It is also because its root system is too thin, so the principle of less fertilization must be maintained for Yingshanhong. If the fertilizer concentration is too high, flower friends often ask: will azalea fall leaves in winter? It will definitely happen.
4. Temperature and sunshine
Rhododendron is a negative flower, and the optimum growth temperature is 12 ~ 25℃. Therefore, we must pay attention to shade it in late spring and early summer. The temperature rises gradually in spring and summer, so azaleas should be placed in a cool and ventilated place to avoid strong light burning leaves. When the temperature is suitable in autumn and winter, it should be taken outdoors for proper illumination.
5. Prune rows of plants
Pruning azaleas is a key step in how to raise azaleas, and only beautiful azaleas have appreciation value. On the other hand, if its lines are messy, no one will want to see it. Therefore, we can prune some diseased branches, weak branches and messy branches after the flowering of azaleas, so that azaleas look more and more Gu Zhuo-like.
growing environment
Rhododendron is one of the three famous natural wildflowers in China, one of the four alpine flowers in the world, and also an important forest vegetation. Rhododendron is born under sparse shrubs or pine forests in mountainous areas at an altitude of 500-1200 (-2,500) meters. It likes acidic soil, and it doesn't grow well or even can't grow in calcareous soil. Therefore, soil scientists often regard rhododendron as an indicator crop of acidic soil. Rhododendron likes a cool, humid and ventilated semi-cloudy environment, and is afraid of extreme heat and cold. The suitable growth temperature is 65438 02℃ to 25℃.
Sun protection is required in summer, and attention should be paid to keeping warm and cold in winter. Avoid exposure to the scorching sun, and it is suitable for growth under scattered light with low light intensity. If the light is too strong, the young leaves will be easily burned, and the old leaves will also be scorched, which will lead to plant death in severe cases. Cold-proof measures should be taken when planting rhododendron in the open field in winter to ensure its safe overwintering. Among the ornamental rhododendrons, Rhododendron occidentalis has the weakest cold resistance, and freezing injury is easy to occur when the temperature drops below 0℃.
