Why do the leaves of the rose plant turn yellow and dry around the edges? What is the reason for the yellowing and drying of the leaves of the rose plant?

(From the second group of training camps)

From the leaves in the above picture, we can clearly see the drying and yellowing of the leaf tips and edges, which is a typical symptom of fertilizer damage. Do you also think it's fertilizer damage?

However, according to the feedback from flower friends, this rose has not been fertilized recently, and from the appearance of the leaves, if it is fertilizer damage, it should be severe fertilizer damage. But since there has been no fertilization recently, this factor can be ruled out. Then, what could be the deep reason causing this?

Not alone, in the flower wall creation camp, a flower friend also encountered the same problem. Please see the picture below:

Also, no fertilization has been done, which seems quite strange, right? In fact, this phenomenon should be quite common recently. Today, taking advantage of the questions from these two flower friends, I will analyze this for you and give a reminder, hoping everyone will pay attention.

Reasons for the massive browning of rose leaves in autumn

The phenomenon of a large number of dry and yellow leaves appearing from the leaf tips and edges of rose leaves is mostly caused by the following three reasons.

1. Fertilizer damage

Why do the leaves around the rose bush turn yellow and dry?

Fertilizer damage is what we are all familiar with because it is often encountered during the cultivation of potted plants. To avoid fertilizer damage in roses, thin and frequent fertilization should be practiced, combining long-acting and fast-acting fertilizers, as well as organic and inorganic fertilizers. This can help grow strong and flowering roses.

You can refer to the book "How to Grow an Explosive Rose from Scratch" written by the Green Plant Enthusiast website for specific fertilization methods. It has very detailed and practical rose cultivation methods.

However, the roses of our flower friends have not been fertilized, so fertilizer damage can be ruled out. Let's look at the second reason.

2. Drought

The weather in autumn is relatively comfortable and not as hot as in summer. Many flower friends think that since the weather is cool, water consumption is slower, and there is no need to water the roses frequently. However, this is not the case.

Although the weather is no longer hot in autumn, roses are in a period of vigorous growth and consume a lot of water. Therefore, compared to summer, the water consumption is not much less. If we neglect watering, it can easily cause rose drought.

When roses are too dry and exposed to sunlight, it can cause a large number of old leaves to lose water quickly, resulting in dry, brittle, and yellowing symptoms, which are very similar to severe fertilizer damage.

This type of drought is acute and often occurs in summer and early autumn when the temperature is still high and water consumption is significant. If it's a slow drought, it usually manifests as a large number of yellow leaves on old leaves, similar to the feeling of autumn yellowing.

What we can do about this acute drought phenomenon is to first supplement water and thoroughly water the potting soil. The fine roots of such roses have already been severely damaged, so we need to recover the seedlings first. Do not use nitrogen fertilizers to promote seedlings temporarily and can use a small amount of phosphorus and potassium fertilizers and root growth powder to promote new root growth in roses.

The yellowing leaves of the two rose friends mentioned at the beginning of the Green Plant Enthusiast website were caused by drought and lack of water. In fact, watering rose potted plants is a technical skill that requires adjusting the amount and frequency of watering according to different environments and climates. This topic is quite lengthy, and interested flower friends can refer to the introduction in the book "How to Grow an Explosive Rose from Scratch."

3. Drug damage

Drug damage is also a common cause of leaf burning, especially with some highly effective insecticides and fungicides. If the concentration is incorrect, obvious leaf tip and edge dehydration symptoms can appear the next or third day after spraying.

Drug damage is irreversible and can only be mitigated by using growth regulators to stimulate rose growth to metabolize the drug residues. Therefore, it is important to pay attention to the concentration instructions when applying pesticides.
