Causes of yellowing of leaves in growing flowers in winter
In recent days, many flower friends have left messages to the editor backstage, asking why the leaves are yellowing. In fact, in winter, potted flowers at home are prone to yellowing of leaves if they are not paid attention to. The main reasons are as follows:
Too much watering.
With the decrease of air temperature in winter, the soil water evaporation decreases, and at the same time, the water transpiration on the surface of flower leaves will also be relatively reduced. if we still follow the inertia and water as before, the basin soil will be too wet for a long time and lack of oxygen in the soil. it will cause some fibrous roots to rot, affect the leaves and make them yellow. At this time, watering should be controlled immediately, and the soil should be often loosened to keep the soil in the flowerpot well ventilated.
Lighting problem
Some flowers that like bright light, such as poinsettia and Fusang, if they are placed in a shady place after entering the house, the leaves will often turn yellow due to lack of light, just like in summer, when we put the shade-loving asparagus and tortoise-backed bamboo in places where the light is too strong, it will cause the leaves to turn yellow. Therefore, we should pay attention to the rationality of the placement of flowers.
The temperature is too high.
Now many flower friends in the north have ground heating in their homes, but due to geothermal heating, the water temperature coming out of the boiler is about 50 degrees, and the backwater is nearly 40 degrees. When the water from watering the flowers seeps into the pan under the basin. Due to geothermal heat, the water temperature is about 30 degrees or higher than 30 degrees. This kind of heat rises, string into the flowerpot through the bottom hole, and burn the flower root into a water stain, or burn it to pieces. Loss of absorption function.
