1. Too much wateringThe money tree does not require much water. If you water it too much, the roots of the plant will be submerged, which will inhibit its breathing and hinder the absorption of water and nutrients, causing the leaves to turn black. When watering, you must control the amount of water. If there is water accumulation, you need to drain it in time, loosen the soil appropriately and increase ventilation so that the water can evaporate as soon as possible. 2. Increase the temperatureMoney tree likes a warm environment. The temperature in winter should be controlled above 10℃. If it is lower than 5℃, the plant will easily be frostbitten, causing the leaves to turn black. Before winter, move the plants to a warm place indoors in time to prevent them from being frostbitten. If the indoor temperature is low, you need to put a plastic bag on the top of the plant to keep it warm. 3. Strong sunlight exposureThe money tree likes sunlight but cannot tolerate exposure to the sun. If it is placed in the hot sun for a long time, the plant will be sunburned and its leaves will turn black. In summer, it needs to be properly shaded to avoid direct sunlight. Especially at noon, you need to put it in a semi-shaded place, and put it back in the sun in the morning and afternoon. 4. Infectious DiseasesIf the money tree suffers from certain diseases, its leaves may turn black, such as brown spot disease, anthracnose, etc. When the plant becomes sick, the diseased branches and leaves need to be cut off immediately, and the plant should be treated by spraying carbendazim or other drugs. Usually, we should maintain good ventilation to reduce the possibility of germs breeding. At the same time, appropriate fertilizer should be applied to improve the plant's disease resistance. |
