Many of the friends who cultivated the flowers reflected that the potted azaleas had nourishment and they died, especially after the flowering. What caused the azaleas to be poorly fed?
The main reason for the death of Du Fu after it was fallen was excessive consumption of nutrients. After the azaleas bloom, their spent flowers often do not settle down, which will consume a lot of nutrients. In order to prevent nutrients from being consumed in a nutshell, the residual flowers should be removed in time to allow the nutrient supply to germinate new branches. At the same time, appropriate amount of fertilizer should be applied, and the nutrients needed for growth in the following year should be made up in accordance with the principle of “thinly applying the principle of thin and thinning the plantâ€. In addition, we must pay attention to the rhodopsin physiological yellow. Azaleas have high levels of looseness, strong permeability, well-drained, humus-rich acidic soils, and a suitable pH of 5-6. Some flower growers do not change the basin for the long-term use of the rhododendron, often causing the roots to stretch and the soil nutrients to become exhausted after the plants grow up. The pottings are alkalized and iron ions accumulate, making the plants iron-deficient, and the leaves lose their green and yellow, even Withered. Therefore, some 0.2% ferrous sulfate solution should be sprayed frequently to acidify the potted soil, which can ensure the normal growth of the plant.
