Green leaves, yellow spots, how to save the rose if it's dead or alive?

Rose leaves appear yellow leaves and spots, what is the cause of this? Let's take a look! Last night, the flower friend came to ask me again about the rose leaves, this time talking about the Longsha gem. Lonza, as a classic European Fujimoto rose, the pink flowers fascinate many people. Among the popular roses, Longsha can be regarded as a more noble rose. For the love of beauty, many people want to raise a few trees, but if there are such yellow leaves, what should they do?

Analysis: look at the state of the leaves and find that the veins of the leaves are yellow and the whole piece belongs to the problem of yellow leaves. There are spots on the edges of the leaves, which feel like sunburns.

Q: what is the cause of this kind of rose leaves?

A: for such rose leaves, I think we need to analyze and solve them from the following points.

The problem of element deficiency

This is due to the lack of trace elements in the soil and the lack of foliage supplement. Secondly, a large number of chemical fertilizers are used, resulting in green plant deficiency and yellow leaves.

Solution:

The method of foliar spraying and watering can be solved by using two-pronged method. Use good organic nutrient solution or chelated trace elements once every 7 days. In general, yellow leaves will turn green slowly, but not seriously.

Watering problem

Long-term excessive watering can easily lead to stagnant water in the basin soil and cause hypoxia to cause root rot. This watering problem is a clich é, novice maintenance is easy to "make mistakes". Many people are used to watering without considering the moisture below the 5cm of the soil. It is suggested that the autumn rose still needs to be managed in accordance with the summer, watering once every 4 days.

Soil problem

The choice of poor soil permeability + unscientific watering has led to the scam of many people. There are only two ways to solve this problem, controlling watering and changing the soil. We all know that if the rose is slightly sour, choose the soil with good ventilation and high nutrients, which can reduce the frequency of soil exchange and accelerate the growth of the autumn rose. And burst into blossom.

Secondly, the spots seen are actually caused by insect pests. The following picture is similar to the harm of small green insects, not thrips and aphids, can be sprayed with a common insecticide. When choosing rose seedlings, we should pay attention to the diseases of the leaves.

The flower friend finally pulled out the root system and cleaned it, and found that the root system was not a big problem. But the new capillaries are few, and most of them are old roots. It shows that the root activity is poor, so it can be judged as the yellow leaf caused by poor root system and element deficiency. It can be solved by recuperating with a good nutrient solution for 15 days.

All right, this is an analysis and solution of yellow rose leaves. If you find it helpful, please like it.
