Analysis of the reasons for the yellowing of new leaves on roses and how to deal with it
The editor will discuss the introduction of green plants and flowers about the reasons for the yellowing of new rose leaves and how to deal with the yellowing of new rose leaves. The editor of this site will introduce to you next.
Recently, I have received many consultations from flower friends about the yellowing of new rose leaves. Many flower friends have also asked about this problem in the iAsk Circle. Today, let's specifically analyze the reasons for the yellowing of new rose leaves.
Reasons and characteristics of yellowing of new rose leaves
The phenomenon of yellowing of new rose leaves is most likely to occur in potted roses, while it is less common in ground-planted roses. The main reasons are as follows:
1. Single potting soil composition
Why is it that potted roses are more likely to have yellowing of new leaves, while ground-planted roses do not appear to have this problem? The main reason is that we use media to mix the potting soil for potted roses, so the nutrient components in the potting soil are directly related to the media we use.
If we use some media that do not contain nutrients or the variety of media is too single, it is easy to cause the potting soil to lack comprehensive nutrients, leading to calcium, magnesium, iron, and other trace element deficiencies in roses, which directly manifests as yellowing and chlorosis of the leaves.
Therefore, when configuring the potting soil for roses, it is recommended to diversify as much as possible and add some media rich in trace elements, such as compost, volcanic rock, and red jade soil, to prevent potting soil nutrient deficiencies.
2. Root damage caused by improper management
Many times, the nutrient deficiency in potted roses is not due to the potting soil but rather the roots.
Attentive flower friends will find that roses that have suffered from fertilizer damage often have new shoots that easily turn yellow and chlorotic. This is because the root damage caused by fertilizer damage leads to poor absorption, resulting in malnutrition and nutrient deficiencies.
In addition to fertilizer damage, root damage caused by excessive watering and闷根 can also easily lead to nutrient deficiencies in roses. Therefore, avoiding root damage during maintenance is very important. Flower friends who do not know how to care for roses can follow the methods introduced in the book "How to grow roses from scratch" step by step.
3. Climatic environmental impact
Why has the incidence of yellowing of new rose leaves been so high recently? In fact, it is mainly influenced by the climate. This year's weather is relatively abnormal. After entering May, the weather is very hot when it is sunny. At this time, due to the high temperature, the potting soil is easily sunburned, causing the roots to have absorption problems.
Moreover, after the first bloom, the consumption is significant, and it is easy to have nutrient deficiencies. These deficiency symptoms are generally mild and can improve with the growth of new rose branches. However, if the maintenance is poor, it can also worsen.
The most common cause of yellowing and chlorosis of new rose buds is iron deficiency, so many flower friends will supplement ferrous sulfate separately. However, the reason for iron deficiency is mostly due to poor root absorption, so the effect of applying ferrous sulfate to the roots is relatively poor. Moreover, sometimes there may be a lack of calcium or other trace elements. For beginners, it is still very difficult to distinguish which trace element is missing. It is recommended to use multiple trace element fertilizers to supplement multiple trace elements at the same time.
Sugar wood enzyme is a saccharified organic trace element fertilizer, diluted 500-800 times for foliar application, which can be transported through sieve tubes directly to plant organs such as leaves, flowers, fruits, and roots. It has targeting, quickly activating plant absorption capacity, supplementing multiple trace elements, correcting yellow leaves, and improving plant resistance.
