In April this year, the transplanted begonia tree species were in the yard at home, but in the past month or so, it was found that the newly grown leaves were yellow and white, and finally slowly dried up. What happened?

Answer content:

Hello, Comrade Li! The new leaves of Begonia turn yellow and dry because of iron deficiency, and the yellow leaves turn pale seriously (only the veins are green) and dry and fall off. cause

Yes: 1. When the rainy season comes, the soil water content is too high and the soil permeability is poor, so it is difficult to absorb iron. 2. Too much rain or watering leads to vigorous growth of begonia buds, resulting in insufficient iron supply; 3. The soil is alkaline or too much phosphate fertilizer is applied.

Iron is easily fixed and not easily absorbed by plants. All the above reasons can cause the new leaves of branches to turn yellow.
