What are the reasons for the yellowing of new leaves on roses
After pruning, roses will grow a lot of new buds and branches, but it may be noticed that the color of the new leaves and branches of the roses gradually loses green. What is the reason for this? In fact, this situation occurs because roses show a deficiency in trace elements, which mainly results from three causes.
1. Fertilization was not promptly补充 after flowering
Roses are plants that thrive on abundant fertilization, and due to their continuous growth and flowering, they consume a lot of nutrients. If we do not replenish the nutrients after flowering, the excessive consumption will lead to the yellowing of the leaves. Therefore, when growing roses, it is important to ensure sufficient fertilization, especially after flowering.
Usually, the best way to fertilize after flowering is to use some organic fertilizers. I usually use a growth-promoting nutrient solution because it not only provides sufficient nitrogen, phosphorus, and potassium but also contains a rich variety of trace elements, which can prevent the leaves from showing a deficiency.
2. Caused by high temperatures
Especially now in the summer, as temperatures rise, the absorption ability of rose roots decreases significantly, and the roots cannot supply nutrients and water to the leaves normally, leading to a deficiency in nutrient elements in the new leaves and branches at the top of the plant.
In this case, we cannot apply fertilizer to the roots. The simplest way is to spray a small amount of trace element fertilizer on the leaves, which can effectively improve the yellowing of the leaves.
3. Improper care
Due to improper care during the maintenance of roses, the roots may be damaged, leading to root rot. This prevents the plant from absorbing water and nutrients normally, which can easily cause a deficiency in the new leaves and branches.
In such cases, applying foliar sprays can help. For the first reason, we can use direct root fertilization to solve the problem, but if it's the second reason, applying root fertilizer again can easily cause severe root damage and lead to fertilizer burn, which is very harmful to the growth of roses. Therefore, this problem can only be solved by foliar sprays.
