Canna is a common ornamental plant. Its flowers are golden and bright, and the leaves are wide and turquoise, which has a high ornamental value. However, during the maintenance process, the phenomenon of yellowing and drying of canna leaves occurs from time to time, which affects the overall appearance of canna. Today, let's take a look at the reasons and solutions for the yellowing and drying of canna leaves.
First, nutrient deficiency is one of the main reasons for the yellowing and dryness of canna leaves. Canna has a high demand for nutrients. If it is not fertilized for a long time, or if it is not fertilized properly, it will cause the canna plant to lack nutrients, which in turn will cause the leaves to turn yellow. The solution to this problem is to fertilize the canna plants regularly, paying attention to the balance of nitrogen, phosphorus and potassium fertilizers when fertilizing, and avoiding excessive application of a single fertilizer.
Second, improper water management can also cause canna leaves to turn yellow and dry. Canna prefers moist environments, but is not tolerant of moisture. If you water too much, it will cause a lack of oxygen in the roots of the canna and the leaves will gradually turn yellow. And when there is a lack of water, the canna plant will also dry up the leaves due to the lack of water. Therefore, in the process of maintenance, it is necessary to grasp the timing of watering and follow the principle of "seeing dry and wet".
Third, insufficient light is also one of the reasons for the yellowing and dryness of canna leaves. Canna loves light, and if left in the shade for a long time, the canna leaves will gradually lose their luster and become dry. The solution is to move the canna plant to a well-lit area so that it receives full sunlight. In summer, the sun is strong, so avoid direct sunlight to avoid burning the canna leaves.
Fourth, sudden environmental changes may also cause canna leaves to turn yellow and dry. Canna is adaptable to the environment, but if you suddenly change the maintenance environment, such as moving from indoor to outdoors, or from a cool place to the sun, the canna leaves may appear yellow and dry. In this case, the environment should be gradually adjusted so that the canna plant gradually adapts to the new environment.
In short, in order to solve the problem of yellowing and drying of canna leaves, we must first find out the cause, and then take corresponding measures to ensure the healthy growth of canna.
