Clematis are often known for their different flower colors and attractive green leaves, so if the foliage starts to turn white or pale, then you know something is wrong.
It’s often a sign that care is to blame or that nature is to blame for the discoloration, but it’s more likely a bit of both.
Fortunately, if a clematis turns white or pale, it’s not as bad as other discolorations, such as blackening of the leaves, which is certainly cause for concern.
That being said, here are the main reasons for white leaves on a clematis and how to fix it today.
loss of light
One of the main causes of white leaves on clematis is lack of sun or light in general.
These plants need lots of bright light every day, usually full sun, and if you don’t get enough the plant won’t grow as well as it normally would.
If clematis doesn’t get enough light, it can cause chlorosis (loss of chlorophyll) resulting in white, pale, or yellow leaves.
Ideally you should give the plant at least 4 hours of full sun a day to avoid chlorosis and also to ensure beautiful flowers every season, because without lots of light you won’t get strong flowers.
Solution
If you’re growing outdoors, find a spot that gets several hours of full sun each day, even if the spot is a bit shady, that’s fine.
You just don’t want to grow in low light, that’s all.
Although clematis plants need lots of light, you should always be wary of temperature extremes during the hottest times of the year because the leaves can be sunburned and red or have other problems.
If you plan to grow indoors, most windows will provide enough light, but if for some reason they don’t, consider turning to an indoor grow light.
I recommend this one by the way.
In general, you can expect your clematis leaves to slowly recover and return to that beautiful green color once the light issue is resolved.
harmful
Unfortunately, Clematis plants cannot escape the occasional infestation, just like most other plants.
Sometimes things happen even when your care has been adequate.
Some pests you may encounter are aphids, mites, scale insects, and thrips.
These particular pests love to feed on the leaves, absorbing nutrients and, in turn, turning the leaves white and/or pale.
Some signs that you have a pest problem are as follows.
- rolled up leaves
- Fallen or withered leaves
- White or pale leaves
- yellowing of leaves
- holes in the foliage
- Bumps on the leaf surface.
- Pests visible as small white or black dots.
- Spider web a sign of red mite
- sticky sheets
- understory growth
Solution
A common way to control pests is to use a cotton swab dipped in alcohol to remove the pests by hand and clean the surface of the leaves.
This is a great method however, if you don’t want to get close to anyone you can try neem oil which I usually recommend for parasites.
The reason for this is that all you have to do is spray the leaves and/or soil of the plant and that will kill them and keep them away.
Plus, it also works great for mold issues.
I recommend this neem oil if it’s something you want to try.
Either way, both methods are ideal for getting rid of those pesky pests from your clematis.
Once they are gone, prune the damaged leaves and wait for new shoots to appear.
powdery mildew
If you notice that the leaves of your clematis have developed a powdery white substance, you have what is called powdery mildew.
Powdery mildew is a fungal problem that can be caused by poor growing conditions or just plain bad luck, as the spores can travel with the wind and infect plants up to 100 miles away.
Fortunately, powdery mildew isn’t very harmful to plants, but it can strip nutrients from leaves and cause discoloration or dryness.
Here are some ways to actively prevent or reduce the risk of powdery mildew developing.
- Provide good air circulation
- Also prune the overgrown areas of the plant to get more air circulation.
- Reduce humidity if necessary
- Don’t let the water stay on the leaves or on the ground.
Solution
There are actually several ways to get rid of powdery mildew, depending on what you’re working with.
A fairly popular method is to use a tablespoon of baking soda diluted in a liter of water and then pour it over the soil and/or leaves.
It works surprisingly well.
You can also use some forms of fungicides, like the neem oil I mentioned above, as well as copper-based fungicides.
Once the powdery mildew is gone, your clematis leaves will turn from white to green in no time.
conclusion
There you have it, the most common causes of your clematis leaves turning white or pale and how to fix them.
As always, I hope you can identify which of these causes is the cause and then have an aesthetically pleasing clematis for years to come.
Have fun gardening and enjoy the experience!
