Yellowing Cyclamen Leaves: Solutions For Leaves Turning Yellow On Cyclamen
The leaves of cyclamen are not only beautiful but they have their own special beauty. They are called “yellow” because the color of these leaves changes from greenish yellow to white when exposed to sunlight. When the sun shines on them, they turn yellow and become less attractive than before.
Cyclamen leaves may change colors due to many reasons. Sometimes it’s due to too much or insufficient light, other times it’s due to age and time, sometimes it’s due to pests and diseases. But all of those causes will lead to the same result – yellowing leaves. You can’t control what caused the color change, but you can take steps which will prevent further deterioration of your cyclamen plants’ appearance.
When you see yellowing leaves on your cyclamen plants, it means that there are several factors involved in the process. Let’s look at each one of them individually.
1) Too Much Light: If you have too much light shining directly on your cyclamen plants, then the color change will occur very quickly.
There is no way around it – if you don’t provide enough light for your cyclamen plants, then they won’t survive long term. They need 6 to 8 hours of direct sunlight daily. If you can’t provide that much, then make sure you choose plants that are tolerant of lower light conditions.
2) Too Little Light: If you have not enough light shining on your plants, then the leaves can turn yellow, but it will take longer time to occur.
Sometimes the process of yellowing starts from the middle of the leaves and it moves toward their tips. If you don’t see any other signs of problems, then the yellowing of leaves is due to insufficient light. In this case, you can relocate your plants to a brighter area or grow them under stronger lighting.
3) Age: The older the cyclamen leaves get, the more inclined they are to show yellowish patches on their surfaces.
This is absolutely normal and you shouldn’t worry about it. Just make sure that all the other factors (light, temperature, humidity, etc.) are ideal for your plants and they will be fine.
4) Too Much Nutrition: If you feed your cyclamen plants with too much fertilizer, the older leaves will start turning yellowish, especially the edges of theirsurfaces.
It’s not deadly to the plant, but you will definitely see a negative response to it. The best way to prevent this is to fertilize your plants in intervals. Use whatever fertilizer you are using, but apply it every 2 to 3 weeks.
5) Poor Nutrition: If your cyclamen plants don’t get enough nutrition, their leaves will start turning yellow from the middle and then towards the edges.
They can even turn completely yellow. There are 2 ways you can solve this problem: one way is to transplant your plants to better growing conditions, the other one is to provide constant feedings with a high quality plant food.
6) Temperature: If the temperature is either too hot or too cold, it can lead to leaf yellowing in your plants.
The ideal temperature for cyclamen growing is about 65 degrees Fahrenheit. Try to keep the temperature around this level if you want to prevent leaf color changes.
7) Too Much Water: If you water your plants too much, their roots will start rotting and this will lead to a chain reaction of problems in your plant’s overall health.
One of the signs that your plant is suffering from over watering is the yellowing of leaves. If this happens, refrain from watering your plant for a few days and this should help to correct the problem.
8) Too Little Water: The lack of water can cause yellowing in leaves, but it takes longer time than over watering does.
In addition, you will also see other symptoms such as shrinking stems and wrinkled leaves. Reduce your watering intervals to prevent this from happening.
If you are seeing signs that your plant is experiencing any of these problems, the first thing you should do is figure out and correct the problem for the long term. Then, to address the immediate problem of leaf yellowing, you should stop all waterings (but continue with fertilizers if necessary), remove any insect pests with soapy water, and move your plant into a very bright location.
If after a few days the yellowing hasn’t decreased in the least, then you may need to throw the plant away. It’s better for you to get rid of it now while the problem is still contained, than to risk it spreading to your other plants. Discard of it properly so that no animals or people will be tempted to dig it up and eat it.
The absolute worst thing you could do is nothing at all. If you don’t take care of your sick plants, they can (and will) spread their disease to your other plants. Don’t think that just because yours didn’t look as bad that it won’t affect yours anyway. It can easily hitch a ride on your clothing, in some of your tools, or on the bottom of your shoes.

If you have followed this guide so far, then you have learned how to identify what is wrong with your sick plant and how to go about fixing the problem. Now all that’s left to do is wait for your sick plant to either get better or die. Don’t get discouraged if your plant doesn’t immediately bounce back. Some problems are bigger than others and it may take a while for yours to recover. You just need to be patient and consistent in caring for your sick plant.
If your plant dies, all isn’t necessarily lost. Most plants will regenerate from their roots if they have not been dead for too long. So, take the lessons you learned from this experience and try again. If you still have problems, check out the FAQ and ask questions about things you are not sure about.
