You might want to keep an eye out for signs that your calathea is infected with a disease. For example, you could notice that the leaves of the plant are wilting or browning.


Calathea leaves generally turn yellow when they are overwatered. To give the greatest growth circumstances for the plant, the soil should be somewhat wet at all times.

In contrast, if you keep them in a moist container, not only will the leaves become yellow, but the roots may also be injured.

If you see yellowing leaves, investigate the soil and look into the plant’s roots immediately away. Check for any soft, brown areas or a rotting stench, since these might be symptoms of root rot, which can be devastating.

Soil testing will assist you in determining how frequently and how much to water your plants. A routine is hard to maintain. If you don’t have a moisture meter, use your finger instead.

If the soil becomes dry before then, simply water the top half an inch. Wet it fully so that the water may drain through the holes and eliminate any accumulated residue.

The significance of watering in Calathea management involves consideration of the following factors:

Water Quality:

Calatheas are quite fussy about the water quality they are exposed to, hence many farmers only cultivate them with rainwater or distilled water.

Aside from the chlorine and chloramine poisons, the yellowing of the leaves may be caused by mineral and salt accumulation in tap water.

If the mineral content of your tapwater is too high, you should consider switching to a purer water source. Make sure it’s at a comfortable temperature.

Potting Mix:

Calatheas require a highly precise moisture condition, and potting mix with soil is essential for this. You’ll need a medium that’s light, airy, and porous.

The combination should be water-retentive but airy enough to avoid becoming stodgy. See this page for detailed information on making the best potting soil.

Inadequate Drainage:  Without proper drainage, even the greatest soil may become a muddy bog.

Dry Soil

However, if the soil becomes too dry, the Calathea will become stretched very quickly. It, like stress in general, can induce yellowing.

Calathea leaves do not droop visibly under dry conditions, unlike the leaves of other plants, hence they cannot be used to determine whether or not the plant requires water.

Their flowing foliage reacts so significantly to variations in temperature and light that it cannot be used as a barometer.

If your Calathea closes its leaves during the day, it might be a sign that the soil needs to be watered, but don’t rely on it. The soil must be regularly monitored.

Low Humidity

For maximum development and flowering, many tropical plants, such as Calatheas, demand humid conditions. They might be able to survive times of low humidity, although the stress may lead their leaves to yellow.

Despite their native environment’s high humidity levels of 90% or greater, indoor plant humidity levels can range from 50% to 70%.

Although the Rattlesnake Plant (Calathea lancifolia) is known to be the most tolerant to low humidity, it nevertheless dislikes dry air.

The following methods can be used to enhance humidity:

Room Humidifier: A humidifier is the workhorse of horticultural instruments for the diligent guardian of a Calathea collection in camera-ready condition. However, they involve more work, and there are simpler ways to raise the humidity.

Grouping Plants: Calatheas make a lovely tropical collection, and by keeping them close together, you may be able to increase the humidity in the area.

It’s vital, though, not to pack them in too tightly. Keep the place adequately ventilated and on the lookout for any insects that may try to infiltrate your group.

Water-filled Trays: Evaporation may be used to boost humidity in a space by putting water-filled trays around it.

To maintain the container above the water level, place the trays near the plants or the stones under the pots. You may use seashells upside down on the soil as miniature reservoirs for watering plants to help retain moisture and avoid root rot.

• Misting – Some growers feel that spraying their Calatheas is advantageous, despite the fact that misting is too brief to have a major influence on overall humidity.

If misting does not significantly boost humidity, it may nevertheless help the plant by watering the air surrounding it without wetting the soil.

Using the same water you use for watering is a great method to avoid leaf stains. Before misting, always ensure that there is enough air circulation around the plant; otherwise, you risk fostering fungal issues.

Incorrect Lighting

There are many different kinds of plants that have yellow leaves. However, they all have one thing in common. Their leaves turn from green to yellow when exposed to light.

This is true with Calathea. This plant grows in tropical climates, where it gets plenty of sunlight.

When you move the calathea indoors for the winter months, its leaves start to change color. The reason why this happens is that the leaves are constantly absorbing more energy.

If you want to keep your houseplant looking healthy, then you should make sure to provide it with enough natural light.

You can also use artificial lights to help brighten up the room. If you don’t get enough sunlight, then you may need to repot your plant into a larger pot, so that it will receive more rays.

When you’re choosing a new indoor plant, be careful to avoid buying any that look like they might be sick or dying. Also, try to choose something that has vibrant colors and lots of leaf detail.


A plant that is acclimated to the sun will have a different color than one that doesn’t get enough sunlight. If you live in a temperate climate, you will need to give your plants plenty of light to grow well.

When you first buy a houseplant, you should make sure that it gets the proper amount of light exposure. The best way to do this is to put it outside on the windowsill. This means that it will receive direct sunlight throughout the day.

Temperature Extremes

It’s easy to forget that plants have feelings just like animals. That is why it’s important to treat them with respect, especially when you’re trying to grow a plant indoors.

If you don’t take care of your indoor garden properly, you might end up having to deal with yellow leaves. This article explains how this happens, and also gives some tips on how to prevent the problem.

If you live in an area where temperatures vary widely, then it can be difficult to keep a plant alive through the winter months.

The best way to ensure that your houseplants survive the cold weather is by keeping the temperature inside at around 60 degrees Fahrenheit (15 C). You should never leave your plants outside, even if you think that they will freeze.

When you first bring your plants home, you need to make sure that all of their water is removed. Then, wait until the soil warms up before watering it again. Once your plants are back indoors, you shouldn’t let them get any colder than that.

Fertilization Issues

If you’re trying to get pregnant, then you might be interested in learning more about calathea leaves. Calathea is a plant that grows all around the world. If you want to learn how to make your own fertilizing solution from this plant, then keep reading below.

You should know that calathea isn’t just used to create fertilizers. It’s also been found to help with fertility problems.

For example, some women who have trouble getting pregnant suffer from a condition known as polycystic ovary syndrome (PCOS). This is a hormonal disorder where the body doesn’t produce enough hormones.

In order to combat PCOS, you need to consume a lot of calories and lose weight. However, it can take years before your body starts producing healthy levels of estrogen and progesterone.

When you start taking calathea, the hormone-producing glands in your body will increase their production. As a result, your body will start making the right amount of these two important hormones.

If you want to prevent yourself from getting burnt by calathea, then make sure that you wear protective clothing. You should never handle the leaves of this plant without using gloves.

In addition, you should avoid touching the leaves of any other plants. This is especially true for wildflowers and vegetables.

Many people have been burned after handling these items. In fact, it’s estimated that more than half of all poison ivy cases are caused by contact with the leaves of another plant.

So how do you tell whether or not a particular plant causes a skin reaction? The best way to find out is to look at its leaves. If you see tiny white dots, then you can be pretty certain that you’re dealing with a poisonous plant.

Flushing the Soil

Flush the soil is a process that involves removing all the topsoil from a garden. This leaves the roots exposed, which can cause them to rot. If you’re interested in learning how to flush the soil, here’s a guide.

This method works well for plants like calathea, but it can also be used on trees, shrubs, and flowers. You’ll need to remove the topsoil by hand, and then you can use your shovel to dig up the area.

After you’ve removed the topsoil, you’ll want to soak the ground in water for several days. Then, you should plant new seedlings.

You can do this without damaging the root system of the plants, so you don’t have to worry about losing any growth potential. After you finish planting, wait until spring before you start fertilizing.

Caught in A Draft

If you’re looking to keep your home cool, then you need to install some window air conditioners.

However, many people don’t realize that installing these units isn’t enough. You also have to make sure that they work properly. This is why it’s important to learn how to check for leaks.

When you look at a window AC unit, you’ll notice that it looks like an upside down triangle. That shape comes from the fact that the compressor is located on the bottom of the device.

When you turn the power off, you should be able to feel a slight breeze coming through the vents. If this doesn’t happen, then there might be a leak.

To find the source of the problem, you can use a flashlight to shine light into the vent. If the beam is bright, but the area around the vent stays dark, then you know that there’s something blocking the airflow. Once you’ve found the problem, you should fix it.

Pests and Diseases

Plants that grow in the desert have to deal with lots of things that other plants don’t. One of these is pests.

There are many different kinds of insects, spiders, mites, and more that can cause damage to your garden. Fortunately, you can use calathea leaves yellow to keep them away from your plants.

This plant was first used by Native Americans to protect their crops. Today, you can buy it at stores like Home Depot, and it’s also available online. You can even make your own version of this natural pest repellent.

In order to create a homemade insecticide, all you need is water, some lemon juice, and a few drops of dish soap. Mix the ingredients together, and then spray the mixture onto the leaves. The combination will kill off any bugs that come near your plants.

You can also put the calathea leaves yellow in a bucket filled with soapy water. This should help to deter the insects that are attracted to the smell of the soap.

Repotting Recovery

Repotting is a process that gardeners use to get their plants back into shape after a period of neglect. This article explains why repotting is important, how to choose the right pot for your plant, and when to repot.

When you first bring home a new houseplant, you might be tempted to leave it alone. You want to make sure that you have enough room to grow. However, this isn’t the best way to care for your plant.

Why Are My Calathea Leaves Turning Yellow

If you don’t give it the attention it needs, then you could end up with a sickly looking plant. That’s because you need to water and fertilize your plant regularly.

If you let it sit for long periods of time without doing anything, then you’ll notice that its leaves will start to yellow.

This means that your plant is suffering from nutrient deficiency. The solution is to repot your plant. This involves removing the soil from the bottom of the pot and replacing it with fresh dirt.

Aging Foliage

If you live in the city, you might be wondering why your plants seem to be turning yellow. If so, you’re not alone. Many people have noticed that their houseplants start to look a little bit sickly.

This is due to the fact that many plants rely on sunlight for energy. When the light levels in the room decrease, the plant’s ability to photosynthesize also decreases. As a result, the leaves become more and more pale until they eventually turn completely yellow.

This process happens because the chlorophyll in the leaf starts to break down. The end result is that the green pigment in the leaves becomes less and less effective.

So what can you do about this problem? You should try to keep the light levels in your home at a constant level. However, you shouldn’t expect to see a drastic change. In fact, it may take several weeks before the color of the leaves changes.

New Leaf on Calathea Yellow?

No. Once a leaf goes yellow, there is no turning back. When the entire leaf becomes yellow, it will dry up and fall off.

Even if one side of a leaf becomes yellow, the green side will continue to photosynthesise and keep the leaf alive. Depending on the underlying reason, the progressive yellowing of that calathea leaf may persist or reverse.


Some calathea blooms are particularly spectacular. If they do not receive the attention they demand, they will swiftly express their displeasure. You are not alone in asking what is causing your calathea leaves go yellow; it is a rather common occurrence.

What follows is an examination of the underlying causes of this problem and the measures you may take to address it and prevent it from recurring.

These plants’ popularity stems from the shape and pattern of their leaves. If you provide your plant with the nutrients it requires to develop, it will reward you with lush leaves.
