The lucky tree is a common flower in life. Because it is easy to grow and has good meaning, many people will keep one or two pots at home. So what is the matter with the black spots on the leaves of the lucky tree? How to treat the black spots on the leaves of the lucky tree? The following editor will explain them one by one, hoping to help everyone. Why are there black spots on the leaves of the lucky tree?The black spots on the lucky tree may be caused by overwatering or poor ventilation of the soil. Another reason is that it has been placed indoors for a long time or in a poorly ventilated place, lacking sunlight, and the leaves cannot photosynthesize normally. I think this is also the reason for the blackening of the leaves. The lucky tree is a tropical plant that likes large amounts of water, fertilizer and long days. How to deal with spots on the leaves of the lucky tree1. If there are not many diseased leaves, remove the leaves with lesions; if all the leaves have lesions, don't do anything stupid and pull them out. Who will do the photosynthesis? Just leave them. 2. No matter how many or few diseased leaves there are, you have to apply medicine. In winter, the room is poorly ventilated and it is common for the leaves to get sick. Spraying medicine is necessary, but you cannot use medicine with a strong smell, otherwise people will not be able to bear it. I like to use mancozeb to treat fungi. It does not have a strong smell and is quite effective. There are many scale insects on the lucky tree. How to deal with it?If the scale insects are not serious, it is recommended to remove them manually, after all, pesticides are toxic. You can use tweezers to clip the scale insects, or stab them to death with a sharp object such as a pin. Be careful when catching them manually, and don't let any fish slip through the net. Scale insects are afraid of alcohol. Use cotton dipped in alcohol to wipe the leaves and trunks of plants to remove scale insects and larvae. When there are many scale insects, it is time-consuming and laborious to remove them manually. In this case, pesticides can be used for spraying. Commonly used pesticides include phosmet, omethoate, cypermethrin, malathion, and cypermethrin. Repeated spraying can achieve better results. |
