Why Are the Leaves of the Elephant Ear Turning Yellow? Causes and Control Methods
The leaves of the elephant ear are very large, very beautiful in appearance, and water droplets will drip from the leaves. In daily cultivation, careful attention is needed, otherwise the leaves may turn yellow, affecting the ornamental quality of the elephant ear, so what are the causes and control methods of elephant ear leaves turning yellow?
1. External damage
When planting elephant ears, the spacing between them should be relatively large. But many people ignore this problem when planting, and during the later stage of rapid growth, the leaves expand very quickly, and a relatively close distance may cause them to interlock, competing for growing space and affecting growth. If this situation is discovered during the planting process and the distance is then increased, artificial damage may occur, affecting the nutrient transport of the root system and causing the leaves to turn yellow.
Control method: When planting elephant ears, sufficient spacing should be maintained to avoid the situation of competing for growing space. Also, daily care should reduce external contact with the elephant ear to avoid causing damage.
2. Waterlogging and dust accumulation
Most people cultivate elephant ears in semi-open shed structures, so the elephant ears are exposed outside for a long time, and external dust accumulation is relatively serious. The leaves of the elephant ear are relatively large, and the funnel shape makes it easy for dust to accumulate. Long-term outdoor exposure may lead to dust buildup, affecting the plant's photosynthesis.
Control method: If there is a lot of dust, wash the leaves, or use sprinkler irrigation to prevent it, promoting the plant's photosynthesis.
3. Soil fertility
The environment and soil have a very large impact on elephant ears, and high-quality soil is relatively important. If you have no cultivation experience and use unsuitable soil, such as soil that is too alkaline or not fertile enough, it will cause the leaves to turn yellow.
Control method: If the yellowing of the leaves starts from the highest leaves and slowly spreads downward, and there is obvious yellowing and withering at the stem, it may be insufficient fertility, and at this time appropriate topdressing can be applied.
4. Fertilizer and water
Fertilizer and water are elements needed for the growth of any plant, and the level of fertility will affect the plant's growth, and the same is true for water. If there is excess fertility, seedling burn will occur, causing the leaves to turn yellow. If there is too little fertility, the seedlings will wither and turn yellow. If there is too much water, the roots will rot and the leaves will turn yellow; if there is too little water, the plant will become weak and turn yellow.
Control method: Because the causes of yellowing from fertilizer and water are different, the symptoms that appear are also different. Solve them in a targeted way according to the actual situation: supplement whatever is lacking, and if there is too much water, do a good job of drainage.
The yellowing and withering of elephant ear leaves is mainly due to the above several causes. When planting, observe the situation especially carefully, and judge the cause of the yellowing according to the actual situation, so that the right remedy can be applied.
