If you’re a gardener, you’ve probably experienced the devastation of finding your beautiful croton leaves have suddenly turned brown and withered.
This is a common problem for many gardeners because it’s often difficult to determine what caused the leaf discoloration in the first place.
In this blog post, we will discuss some possible causes of browning croton leaves so that you can better understand how to prevent it from happening again!
Why Are My Croton Leaves Turning Brown?
The leaves on your croton plant are turning brown as a result of overwatering or leaf burn. Overwatered leaves can sometimes be damp to the touch, whereas burnt leaves are usually dry and crispy.
I will now take a more in-depth look into both of these causes and what you can do to prevent them. By the end of it, you should be able to bring your croton back to full health…
Brown Croton Plant Leaves from Too Much Water
This problem can occur because many gardeners don’t understand how much water their plants need and end up drowning them by accident!
This often happens with new (and sometimes even experienced) gardeners who aren’t aware that most houseplants usually require less frequent watering than outdoor plants.
You should only water croton when the top inch of soil is dry. This tends to be once a week during the warm months, but only once every two weeks during the week.
You can test the soil by dipping your finger into the top inch of soil. Only water the plant if you can’t feel any moist soil. Alternatively, you can use a moisture meter to get an accurate reading, which means there will b no need for any guesswork.
As a result of overwatering, your croton plant will end up with root rot (if left untreated). If this has already happened, you should immediately take measures to dry out the soil and repot your plant in a fresh, new potting mixture.
You should also prune the rotten roots if the plant has root rot. Make sure to dispose of them away from your plants to avoid any fungal infection.
Brown Croton Plant Leaves from Too Much Sunlight
The leaves on your croton plant may also turn brown if it is exposed to too much sunlight. Sun scorched leaves typically have sun-scorched, dry edges and are often darker in color than the rest of the leaf.
If your plant is suffering from sunburned leaves, move it to a shady spot where it will be protected from direct sunlight for at least two weeks.
If this happens, you should re-position the plant so that it gets more shade…
A shady porch or windowsill where there is dappled light might be perfect for keeping your plant leaves as green and healthy as possible. You can also hide the plant behind structures or other plants to keep the plant away from direct light.
Although I love using grow lights in the winter months, they should be used with caution. It’s possible to burn leaves if you position the light too close to the plant or you have your light on for too long.
Brown Croton Plant FAQs
Croton leaves are a mystery for many people. As such, I will now answer some of the most frequently asked questions I get in my inbox.
Will brown croton plant leaves turn green again?
No, it is unlikely that brown croton leaves turn green again. However, new leaves will grow eventually if given enough care.
Should I remove brown leaves from croton plant?
Yes, you should remove brown leaves from your croton plant. This is because the dried-up and dead leaves will attract bugs that might then contaminate your healthy plants. It’ll also improve the aesthetic appeal of your plant.
Will too much water cause croton plants to turn brown?
Yes, too much water can cause your croton to turn brown. However, this usually happens when the plant is already in dire straits (such as root rot).
When I touch my croton plant, it seems like there is moisture on it?
This is usually due to overwatering. Guttation is when excess water accumulates on the surface of leaves. If this happens, you should reduce watering to avoid root rot or fungal growth in your croton plant.
Will direct sun cause croton plant leaves to turn brown?
Yes, this is why you should only give in-direct sunlight to your croton plant. Sun-scorched leaves are the result of too much direct sunlight, so it’s best to keep croton in a shaded area.
In conclusion, brown croton plant leaves can be caused by overwatering or too much sun. As soon as you notice this, take measures to prevent further damage and treat the problem quickly!
By taking quick action, your plant should return back to its healthy green state in no time at all. If not – I recommend contacting a professional for help.
