1. Factors causing leaves to turn blackThis plant likes a certain amount of water, but not too much water, otherwise its roots will rot and its normal growth will be disrupted. Sometimes, leaves may become diseased due to pest attacks or low temperatures. In midsummer, it is also necessary to avoid strong light. 2. Solution1. The water supply should be appropriate. You can wait until the soil is dry before watering. Do not water if it is not dry. Moreover, during seasons of continuous rain, you should reduce the water supply, and when the weather is relatively dry, you need to provide it with more water needs. 2. This plant is more susceptible to pests such as aphids and scale insects. We can spray some pesticides appropriately to achieve the purpose of killing insects. If you don't want to use medication, you can also mash the garlic and add 1000 ml of water, stir and spray it. If scale insects appear, you can simply brush them off with an old toothbrush, which can also achieve the purpose of eliminating pests. 3. The temperature is relatively low in winter. If you are raising it in the north, you need to keep it indoors so that it can survive the cold winter smoothly. When caring for it in the south, you need to place it in a sheltered place, cover the plant with a plastic bag, and keep it warm. |
