If you have a rose bush and it’s one of those that throws roses at you, seeing yellow leaves is surely traumatic for you. What can happen to a rose bush with yellow leaves?
If you too need to have an answer and to know the reasons why the leaves of your rosebush are turning yellow (and what to do in those cases), keep reading as we’ve compiled all the possible causes and treatments that might work for you.

lack of chlorophyll
One of the first reasons you may have a rose with yellow leaves is a lack of chlorophyll. In case you don’t know, it is a green pigment with which plants absorb energy from the sun. But if it doesn’t, or it’s very little, then photosynthesis isn’t doing it properly.
What does this imply ? Well, among other things, the plant does not receive the energy it needs, which weakens it and makes it vulnerable to diseases and pests.
In the case of the rose bush, if it does not receive enough sun and does not have enough chlorophyll, it can mean the death of the plant. That’s why you have to see if it’s really the problem and apply a treatment to restore the chlorophyll (or have more sun).
Plagues and diseases
As you know, roses have many pests and diseases that affect them, which can cause yellow leaves to appear on them.
Mites, diseases caused by fungi that affect the sap of the plant, insect attacks, etc. they will inevitably make the leaves change color… Or almost.
If you detect that a pest is doing its job, the best thing to do is to wash the whole plant with neem oil or alcohol to get rid of it. If it is very resistant, you may also need to treat it with a product such as an insecticide.
Lack or excess of watering
As with other plants, in the case of roses, if you go too far with water, or if you lack it, it has consequences.
On the one hand, if the plant lacks water, the leaves turn yellow and eventually fall off. Plus, you’ll notice that they look like paper and break easily when touched.
On the other hand, you have the opposite, that is to say that there is an excess of water. when it happens the roots of the rosebush suffer. A lot. And that causes the plant to stop sending energy to the leaves, which focus on trying to recover from that drowning you caused it.
And it is that, believe it or not, it is through the roots that the plant absorbs both water and oxygen. And if you can’t do this, the plant weakens and may die.
The solution in this case will depend on what is happening.
If you have gone too far with water, it is better to remove it from the pot and change it to another with dry soil, without watering too much (even if it is dry). You will have to wait a few days to see if the plant recovers.
In case of lack of water, you will have to increase irrigation. Of course, we don’t mean that you’re going to go from not watering it to drowning it. In fact, if you do that, you’ll get right into the problem of going overboard with water. It is better to water more times but with less quantity so that there is no problem.
lack of nutrients
Another of the problems of a rose with yellow leaves can be the lack of nutrients. This reason is usually one of the main ones in the case of specimens that have been in one place for a long time (either in the pot or in the ground) and have not been fertilized for a long time.
Over the years, The plant feeds on nutrients from the soil until it stops having them and that’s when it starts to have deficiencies. Additionally, the soil itself raises the pH to a very alkaline level, which is not recommended for roses because it lacks iron, zinc, or manganese, elements that it lacks.
To avoid this, you can add these nutrients. To do this, you can do it with subscribers in irrigation or even spray so that they go directly to the leaves of plants.
thermal stress
The heat waves are huge. But not only for humans, but also for the plants themselves.
When temperatures get too high, plants, like roses, tend to get stressed. and what they do is the leaves turn yellow and fall off. It is a response to this heat.
In general, when the thermometer goes down, it should recover and release new leaves (provided it is the right time, otherwise it will have to wait until the following year).
In this case, try to take care of it as usual, even if it has no leaves, because you will be preparing it for the following year.
Natural growth of the rose bush
If you have a rose bush with yellow leaves, you have surely read all that we have given you as causes. But the truth is, one of the first questions you should ask yourself is which leaves are turning yellow.
And it is that if they’re just the ones at the bottom of the plant, there’s really nothing wrong with that. She is in perfect health.
The only thing that happens to him is natural growth. In other words, the plant dries out the lowest leaves (those near the base of the trunk) because it will give way to new leaves that will sprout at the top.
In this case, all you have to do is remove them so that they do not become a source of infection or where pests or diseases can enter.
As you can see, there are many causes that can end a yellow leaf rose bush. But if you catch it in time, you don’t have to say goodbye to your plant, but treat it so that it regains its vitality and regains the green leaves it always had. Has this ever happened to you with your roses? What happened to them and how did you fix the problem?
