The rubber tree leaves are oily and rich, and the leaves are rotten. This is the culprit that causes the rotten leaves.
A few days ago, a flower friend sent a picture to ask me the reason for the rotten leaves of his rubber tree. Xiao Qi sent it to share with you. When you encounter this situation in the future, you can know how to prevent and prevent it. The leaves of the rubber tree are shiny, and there is no shortage of fat and water. It proves that the cultivation is very good, but the leaves begin to rot and turn yellow. Xiao Qi told us what the reason for this yellowing is and how to treat it. I hope it can help everyone. The yellow of leaves is not the normal aging yellow of old leaves, but a kind of rotten yellow leaves. This disease is one of the most common diseases of rubber trees. Leaf blight, low indoor temperature, poor light and poor ventilation are the three main reasons for this. Xiao Qi, tell me how to deal with it.
The indoor air is not well ventilated in winter. If you are planting in an impervious high basin, the drying rate of the basin soil is very slow. If you water it in winter, the temperature cannot reach the temperature of growth. With large pot species, the root system of the rubber tree is very well developed. There is no problem without watering in winter, and there is no problem to water again at the beginning of spring. The solution is to check whether the plants in the basin are rotten. If not, put the rubber tree in a brightly lit place and cut off all the leaves with rotten spots, which must be all. Those with methyl topiramate are sprayed with methyl topiramate with water 1000 times as much as water. Without carbendazim, you can spray with carbendazim 1vex 800. Stop watering and spray 2-3 times. It is best to change the basin soil at the beginning of spring. The basin soil permeability is very poor. First, the dry soil is slow. Second, watering is not thorough, the bottom is not dry, or it is not silting up all the time. Raising well is the king.
