1. Soil causes

When planting rose flowers, if there are yellow leaves in the rose flowers. Well, the first thing we have to consider is whether or not the soil. Chinese rose likes to grow in soft and fertile soil, and the PH value should be controlled at about 6.5. If the permeability of the soil is too poor and too alkaline, it will lead to poor growth of rose flowers and yellow leaves. At this time, we should remove the rose plant in time, then cut off the rotten roots of the yellow leaves, and then prepare the soil with weak acid and good permeability, and plant it into conservation.

2. Watering reason

Rose has a certain demand for water in its growth. If there is a lack of water, it will have a great impact on the growth of rose. However, water should not be too much, otherwise it will reduce the soil permeability and affect the root growth of rose. So whether it is too much or too little watering, it may lead to the phenomenon of yellow leaves in rose flowers. If too much watering, then timely drainage, dry the soil, reduce the number of watering. On the contrary, if the watering is too little, then it is necessary to appropriately increase the number of watering to meet the water requirements of rose growth.

3. Reasons for fertilization

Fertilizer is also an aspect that we need to pay more attention to when growing rose flowers. When fertilizing, there are many things we need to pay attention to. If we apply too much fertilizer, the rose flowers are prone to fertilizer damage, which leads to the fertilizer damage of rose flowers. However, if there is no fertilization for a long time, then the leaves of Chinese rose may turn yellow because of lack of nutrition. Therefore, if there is too much fertilizer, it can be adjusted by watering, changing soil and other work. If fertilization is too little, then we should pay attention to timely topdressing, increase the proportion of nutrition, and provide adequate nutrition for rose flowers.
