Do you know why your Caladium leaves are turning yellow? Many factors cause Caladium to lose its color. Some causes can be corrected within a short time, while some take a lengthy period.
The primary cause of Caladium leaves turning yellow are moisture stress (overwatering and underwatering) and Nutrient deficiency. Other conditions that can cause yellowing in Caladium are normal aging, Pest and disease, low humidity, and overexposure to sunlight.
Caladium plants are grown for their beautiful foliage. When the plant starts losing its color, the purpose of having them is defeated.
Caladium plants have breathtaking leaves that make the interior beautiful, and when you see your Caladium leaves turning yellow, that means something is wrong.
In this article, we will discuss how to fix leaves yellowing in Caladium and other indoor plants.
Reason Your Caladium Leaves Turning Yellow
Learning to take care of the Caladium plant is the first step towards a healthy and happy plant. Here is the list of reasons why your Caladium leaves are turning yellow and the possible solutions.
1. Low Humidity
Low humidity is one of the reasons your Caladium plant is turning yellow. Provide high humidity levels around Caladium plants for healthy growth, as it will translate to a big leaf.
Thus, if your Caladium plants do not have the required amount of humidity, they end up having yellow leaves.
In addition, low humidity makes the plant transpire further and thus gets the leaves to dry out.
Solutions to Low Humidity
Creating surroundings with high humidity is the easiest solution to this problem. Caladium comes from the tropics and grows in a habitat with more humidity.
Therefore, to prevent Caladium leaves from losing color, you have to provide high humidity for them.
To rectify yellowing leaves, use a humidifier all over the place to keep the moisture levels high. You can grow your plants in groups to increase humidity around them. The transpiration from the plants increases the moist content around your houseplants.
Using a pebble tray can also help to increase moisture around a plant, but this method is not as effective as the humidifier.
2. Moisture Stress
People do ask, why are my Caladium leaves so small? They didn’t know it is as a result of inappropriate watering habits.
Improper watering habits (Overwatering or Underwatering) can lead to poor growth and yellowing of Caladium leavings. And if the growth of your plant is affected same goes with the leaves too.
Caladium strives best in moist soil that is neither too watered nor dry. Therefore, striking an appropriate balance for water is essential if you want the plant to grow with beautiful leaves.
Almost all houseplants get affected by overwatering. Many think keeping plants in wet soil is the best thing for them. But when done wrong may lead to root rot, which appears on leaves as yellowish coloration.
As earlier stated, overwatering makes the soil to over-logged with water. It stops the flow of air in the soils and chokes out the roots by denying them air. Prompting root rot and Caladium leaves turning brown, which further hinders the growth of your plant.
How to Solve the Problem of Overwatering?
- If your plant is in a pot, ensure there are enough holes around for drainage.
- Ensure you mix perlite to your potting soil for better aeration.
- Try not to water the plants except if needed.
- Use good Soil mix for planting Caladium.
- Only water the soil when the top two-inch layer of the earth is dry.
One of the reasons your Caladium leaves is turning yellow is because of underwatering. Underwatering comes to play when your plant does not have the required measure of water they need for survival.
Here are some of the causes of Underwatering:
- When you keep your plant straight under the sun, the water evaporates from the soil and dries it.
- You neglect to water your plant as at when due.
- Less humidity around the plant makes the plant transpire to keep the air damp. And it results in the drying of the plant leading to pale leaves.
Solutions to Underwatering?
- Keep your plant in a little shady environment. It helps prevent direct contact with sunlight that causes excessive evaporation of water.
- Providing a humid place for your plant will help keep your plant hydrated.
- Make sure your pot has holes to let out excess water after watering during dryness.
- Check the soil regularly for dryness. You can do that by trying to push your finger into the earth. If your finger can go through, then the soil is dry.
3. Improper Use of Fertilizer
A high quantity of fertilizer can cause Caladium leaves to turn yellow. And can also hinder the growth of the plant.
Both the overuse and underuse of Caladium can stunt the growth of your plant. So extra care is needed when applying fertilizer.
Regardless of whether you use a lot of fertilizer, only what’s needed by the plant will be utilized. Where does the excess go?
The leftover gathers on the soil as salts and block the ability of the plant to absorb water. Along the line, it can result in smaller leaves and leaves drooping. Also, a lower amount of fertilizer might not be enough for your plant – leading to malnourishment and no growth.
Solutions to the Problem of Improper Use of Fertilizer?
If your plant is experiencing overuse of fertilizers, you can solve it by prolonged watering. This action eliminates the gathered salt and prevents any further accumulation of salts.
Before doing this, make sure your plant’s pot has holes for proper drainage. And if it is in the garden, ensure the plant is in well aerated and free soil.
Preferably, Caladium is fertilized weekly during the growing season. Use Liquid fertilizers or pellets with a slow-releasing ability.
4. Overexposure to Sunlight
Sometimes, when plants’ leaves show signs of distress and start turning yellow, it could be because of too much sun.
Caladium is a shade-loving plant, and it won’t be wise to leave them under the midday sun without providing shades for them.
Leaf burn and dry out takes place when the plant receives too much sunlight. Provide bright indirect light to keep the plant from yellowing.
Not only burned leaves, wilting, and yellowing in Caladium plant. Overexposure to sunlight can cause Caladium to undergo increase transpiration. The excess sunlight can cause stunt growth and small leaves as it tries to respond to adverse conditions.
Solutions to Overexposure to Sunlight
The solution to excess exposure to sunlight is keeping your plant under a shade. Place your Caladium in any location that receives indirect sunlight.
Caladium doesn’t need too much sunlight; bright indirect light can do the job of keeping your plant happy.
While indoors, keep the plant near a window, preferably the west and east-facing windows, where they can get sunlight for a few hours per day.
5. Root Rot
Root rot is one of those conditions that kills Caladium quicker. Its mode of operation is like that of overwatering, where the roots begin to rot and then die.
The damage becomes visible in the upper part of the plant (Leaves) and turning yellow. It happens because the leaves lack nutrients and oxygen.
Solutions to Root Rot
Cutting out the affected root is the easiest way to stop the spread of rot in Caladium plants. Take note of the root healthy roots look firm with a whitish patch, but the roots with rot are brown and flaccid.
When you notice your Caladium has root rot, here are what you need to do:
- Tap the plant from the pot and remove as much of the wet soil as possible.
- Cut off any root material that is not healthy.
- Also, cut back those damaged sections until your reach the uninfected plant material.
- Dry the root ball and re-pot in a new sterile pot using a new potting soil.
- Don’t water the plant immediately after re-potting. Give the soil time to dry below the surface.
- After that, water and keep in place with bright indirect sunlight.
6. Nutrient Deficiency
Nutrient Deficiency is one of the primary reasons why Caladium leaves turning yellow. Yellowing of leaves is due to lack of essential nutrients available for your Caladium plant.
Most Caladiums start losing color, and leaves turn pale when experiencing nutrient deficiencies such as lack of manganese, zinc, or nitrogen, and iron.
Solutions to Nutrient Deficiency
Plant food is essential to all plants, even Caladium. Feed your Caladium with Liquid fertilizer high in nitrogen to encourage leaf growth.
In the summer, feed your plant on a two-week basis and reduce to once a month in the fall. By winter, your Caladium had windup, losing all its leaves, and does not need plant food.
7. Pest and Disease
Many Caladium plants at their peak condition remain pest-free. But it is not exempted from diseases and infections such as viral infection.
Viral infection in Caladium may appear as smeared, spreading yellow patches on leaves all through the plant. And this may go with deformed stems with Caladium leaves turning pale.
Viral infections can spread fast to other susceptible plants nearby and are hard to cure.
Solutions to Caladium’s Disease and Infection
- Separate and quarantine affected Caladium from the rest of your plants.
- Examine the neighboring plants to ensure to stop any spread of disease.
- If the whole plant is not affected by the infection, cut out the healthy parts and re-pot in a new sterile pot using a new potting soil.
- Spray fungicides on the affected plant to kill all contaminants before disposing of them.
8. Natural Aging
Just like any other plant, Caladiums also go through an Aging process. As Caladiums age, the lower leaves will become yellow and fall off. The process is essentially a natural procedure in their development.
In a situation like this, Relax! You can do nothing about it. But, you can ensure your Caladium is safe for next spring by putting away the tubers.
