About Calatheas

You need to remember that Calatheas require high humidity to thrive, so make sure to keep their environment at 60% ambient humidity or above to prevent leaf dehydration and other issues. Unlike other plants, Calatheas lack thick foliage to store water, making them more susceptible to rapid dehydration. Signs of low humidity include brown patches, curled leaves, and stalled growth. This is especially important during the winter and when your plant is recovering from root damage.

To ensure proper Calathea care, it’s important to choose the right location and humidity level for your plant. Consider placing your Calathea in a bathroom or kitchen, where humidity levels are naturally higher. You can also use a humidifier or group your plant with other foliage to increase ambient humidity. Additionally, using a pebble tray or enclosing your Calathea in a transparent barrier can provide extra moisture.

Remember, combining humidity tips can enhance their effects and lead to a thriving, healthy plant.

Ideal Humidity Levels

To maintain the health of your Calathea, it’s important to ensure that the ambient humidity levels are above 60%. This can be achieved by using a variety of methods, including using a humidifier, placing your plant in a bathroom or kitchen, grouping it with other humidity-regulating plants, using a pebble tray, or enclosing it in a transparent barrier. It’s also important to measure the ambient humidity levels using measuring equipment, such as a hygrometer, to make sure you are maintaining the ideal levels for your Calathea’s health.

In addition to using these methods, you can also incorporate humidity-regulating plants into your indoor jungle. These plants, such as ferns and peace lilies, release moisture into the air through transpiration, helping to maintain the ideal humidity levels for your Calathea. By combining these methods and incorporating humidity-regulating plants, you can ensure that your Calathea is thriving in its environment and avoiding issues such as brown patches, curled leaves, and stalled growth due to low humidity.

Signs of Low Humidity

If the humidity around your Calathea drops below 60%, you may notice brown patches, curled leaves, and stalled growth. These are all signs of low humidity. Calatheas lack the thick foliage that other plants have to store water, making them susceptible to rapid dehydration. This dehydration can cause leaf cells to wither and die, leading to brown patches on the leaves.

Low humidity can also cause the growth of your Calathea to stall, making it difficult for the plant to thrive. Additionally, plants that require high humidity, like ferns and orchids, may suffer from the same issues as your Calathea. Leaves may become dry and brittle, and the plant may not produce as many flowers or fruits as it would with adequate humidity.

If you notice signs of low humidity in your Calathea, it’s important to take action to increase the humidity for the health of all your indoor plants.


Maintaining the health of your Calathea also requires understanding its vulnerabilities. These plants lack thick foliage to store water, making them susceptible to rapid dehydration. Signs of low humidity include brown patches, curled leaves, and stalled growth. However, winter and root damage can make them even more vulnerable to dehydration.

To prevent dehydration, it’s important to maintain high humidity levels through the use of a humidifier or other methods.

Winter care is also important for the health of your Calathea. During the winter months, the air tends to be drier, which can lead to low humidity levels and dehydration. It’s important to keep your plant away from cold drafts and to maintain a consistent temperature. Additionally, it’s important to monitor the soil moisture levels and adjust your watering schedule accordingly.

By taking these precautions, you can ensure that your Calathea stays healthy and thrives throughout the winter months.

Location and Room Factors

Choosing the right location for your Calathea is crucial to its health, so it’s important to consider the room size and heating/cooling setup. Calatheas prefer warm and humid environments, so avoid placing them near drafty windows or air conditioning vents that can cause fluctuations in temperature and humidity.

If you live in a large space, it’s recommended to place your Calathea in a smaller room or an area that can be enclosed to maintain the right humidity levels. Additionally, make sure to provide adequate air circulation to prevent stagnant air from accumulating around your plant.

With proper room placement and temperature control, your Calathea will be able to thrive and show off its beautiful foliage.

Maintaining Humidity

To keep your Calathea healthy, it’s important to provide the right environment with high humidity levels and proper air circulation. One way to maintain humidity is by choosing the right location for your plant.

The bathroom is a great spot as it naturally has high humidity levels. The steam from the shower or bath can help keep your Calathea hydrated. If the bathroom isn’t an option, consider placing your plant in the kitchen near the sink or stove where there’s plenty of moisture in the air.

Another way to increase humidity levels is by using a pebble tray. Simply fill a tray with pebbles and add water until it reaches just below the top of the pebbles. Place your Calathea on top of the pebbles, making sure the bottom of the pot isn’t touching the water.

The water will evaporate and create a humid microclimate around your plant. This can be especially helpful during the drier winter months or if you live in a particularly dry climate.

Effective Methods

Maintaining humidity levels for your Calatheas is crucial to their growth and overall health. As mentioned in the previous subtopic, there are various ways to maintain humidity levels such as using a humidifier, choosing the right location, grouping your plants, and using a pebble tray. But what if you don’t have a humidifier or don’t want to spend money on one? Don’t worry, there are some effective DIY humidifying solutions you can try.

One DIY solution is to place a bowl of water near your plants. As the water evaporates, it will increase the ambient humidity. You can also place a wet towel or sponge near your plants, or mist them with a spray bottle. However, it’s important to note that misting is not very effective for increasing humidity levels. Additionally, these DIY solutions may not be as effective as using a humidifier and may require more maintenance. Speaking of which, let’s talk about humidifier maintenance.

By maintaining and cleaning your humidifier properly, you can ensure that it’s working effectively to maintain the ideal humidity levels for your Calatheas.

Other Helpful Tips

If you’re struggling to keep your Calatheas healthy, try adjusting the air circulation in your home. Stagnant air can cause moisture to accumulate in one area, leading to mold growth and other issues.

Here are some ways to improve air circulation in your home:

  1. Open windows and doors to let fresh air in.
  2. Use ceiling fans to circulate air.
  3. Place a small fan near your plants to keep air moving.

In addition to improving air circulation, grouping your Calatheas with other plants can also help combat dry air. Plants release moisture into the air through a process called transpiration, which can increase humidity levels.

This is especially effective if you group plants with similar humidity requirements together. Not only will your Calatheas benefit from the increased humidity, but you’ll also create a beautiful indoor jungle.

Air Circulation

Improving air circulation is crucial for the health of your Calatheas, and there are several ways to achieve this. One of the easiest methods is to use a fan. The benefits of owning a fan extend beyond just improving air circulation for your plants. Fans can also help regulate temperature, prevent the buildup of stagnant air, and discourage pests like spider mites.

When using a fan, it’s important to find a balance between providing enough airflow for your plants without subjecting them to direct drafts. Placing the fan on a low setting and aiming it towards the ceiling or a nearby wall can create a gentle, indirect airflow that will benefit your Calatheas without being too harsh.

Additionally, using a fan in conjunction with other humidity tips like a humidifier or pebble tray can enhance their effects and keep your plants thriving.

Pest Prevention

To prevent pests from invading your indoor jungle, regularly inspect your plants and quarantine any new additions before introducing them to the rest of your collection. Pests can come in many forms, including spider mites, mealybugs, and scales, and can quickly spread from plant to plant if not detected early.

Look for signs of infestation, such as yellowing leaves, sticky residue, or small insects on the leaves or stems. If you detect an infestation, isolate the affected plant and treat it immediately with natural remedies or chemical treatments.

Natural remedies, such as neem oil or insecticidal soap, can be effective in controlling pests without harming the plant or the environment. However, they may require multiple applications and take longer to see results. Chemical treatments, such as systemic insecticides or contact sprays, can provide faster and more thorough control but may also have negative effects on beneficial insects or the plant itself.

Choose the treatment that is best suited for your situation and follow the instructions carefully to avoid any unintended consequences. By being vigilant and proactive in preventing and treating pests, you can keep your Calatheas and other plants healthy and thriving in your indoor oasis.

Watering Techniques

When watering your indoor Calatheas, it’s important to check the soil moisture level before watering. Use your finger or a wooden skewer to feel the top layer of soil and check if it feels dry. If it does, then it’s time to water your plant.

Here are some additional tips for watering your Calatheas:

  1. Frequency & Amount – Calatheas prefer to be kept evenly moist, but not waterlogged. Water your plant when the top inch of soil feels dry to the touch. Be sure to water thoroughly, allowing water to drain out of the bottom of the pot. Avoid letting your plant sit in standing water.

  2. Soil Flushes & Salt Buildup – Over time, tap water and fertilizer can leave behind salts in the soil, which can interfere with root function and cause leaf burn. To prevent this, flush the soil with fresh water every few months. To do this, water your plant thoroughly until water runs out of the bottom of the pot, then repeat the process 2-3 more times. This will help to remove any built-up salts and keep your plant healthy.

Measuring Humidity

If you’re struggling to keep your Calatheas healthy, monitoring the ambient humidity levels can help. Humidity measurement techniques are essential to maintaining the ideal conditions for your plant to thrive.

You can use a hygrometer to measure the humidity level in your room. This device can give you an accurate reading of the relative humidity, which is the amount of moisture in the air compared to the maximum amount of moisture the air can hold at a given temperature.

Finding the right hygrometer is important to ensure accurate readings. There are many types of hygrometers available, including digital, analog, and mechanical ones. Digital hygrometers are the most popular type and are easy to use, read, and reset.

Analog hygrometers are more affordable but can be less accurate and need to be calibrated regularly. Mechanical hygrometers are the most accurate but can be pricey and require regular maintenance. Choose the hygrometer that best fits your budget and needs, and use it to help you keep your Calatheas healthy and happy.
