The reason why the bulb orchid turns yellow largely depends on the place of cultivation. Generally, a suitable growth environment should be selected for the cultivation of bulb orchid. The selection of flower basin needs a sandy basin, and it is better not to use a plastic basin or a porcelain basin. The second is the height of mutual spraying. Generally, it is better to choose a higher flowerpot, so that it can grow more vigorously with the root of bulbila. The quality of root development will affect the growth of branches and leaves. If the root cannot develop normally, it will lead to the lack of nutrient absorption, resulting in the phenomenon of yellow leaves. But flowerpots should not be too large, too large will also affect the growth of the whole plant, according to the size of plant growth to choose the appropriate size of flowerpots.
The application of fertilizer will also affect the growth of the plant when cultivating the bulb orchid. Generally, most people are willing to use the soil selected by themselves for cultivation, and then use liquid fertilizer, and sometimes put a small amount of fertilizer at the bottom of the flowerpot as the base fertilizer. Fertilizer is necessary to use, so can supplement nutrients, but we must pay attention to the amount, according to the growth of bulbil to appropriate fertilization.
Bulblets like to grow in the place with light, which is a shade loving plant, so we should avoid direct sunlight and unnecessary damage to leaves. If there is yellow leaves, it may not be enough time to find, at this time, it should be placed in the position of light for maintenance. In summer, to reduce the time of light on the bulb, put it in a bright environment, so that the leaves will not turn yellow due to the strong light.
