Brown spots on Calathea are usually the result of over-watering or too much direct sunlight. To fix brown spots on Calathea, first ensure that the soil is well-draining and not soggy to the touch. If the potting soil is too wet, consider repotting into fresh, dry soil or using a much smaller pot with better drainage.
Water the plant only when the top 2-3 inches of soil feel completely dry to the touch; when the soil feels damp and cool to the touch, the plant doesn’t need watering yet. Secondly, avoid exposing Calathea to direct sunlight.
Place them near light-filled spots but not necessarily in direct sun, as direct light can cause some of the spots to darken or become more noticeable. If possible, keep the plant in an environment with ambient light and bright indirect light.
If brown spots have already appeared, try cutting off the damaged leaves. The plant should have plenty of new growth which you can remove and transplant elsewhere if desired. Finally, remember to mist the leaves of Calathea regularly with distilled water so the leaves stay hydrated and do not dry out.

Why does my Calathea have rust spots?
Rust spots on your Calathea may be caused by a few things. First, they could be caused by an infestation of mites or scale insects, which will cause the plant to produce extra sugars, resulting in the rusty spots.
Secondly, the leaves may be getting too much direct sunlight, which can also cause rust spots. Finally, the rusty spots may be caused by a common houseplant fungus known as Pseudomonas. This fungus is often caused by over-watering, keeping the leaves wet for extended periods of time, or using water that’s too cold.
In order to remedy the rust spots, you should check the plant for signs of pests and remove any affected leaves. Additionally, make sure to water the plant less frequently and use water that is closer to room temperature.
What does Overwatered Calathea look like?
When a Calathea plant is overwatered, there are certain signs to look for that will help identify if the plant has too much water. These signs include droopy and limp leaves, yellowing or browning of the leaves, mushy or rotted stems and root systems, and it is possible for the Calathea’s leaves to be covered in a white powdery film, which is commonly referred to as mildew.
If your Calathea has been overwatered, the leaves may also feel soft and pliable when touched. You may also see an accumulation of water at the base of the plant and/or water droplets on the underside of the leaves.
In severe cases of overwatering, it can cause the stems and leaves to turn black and die.
How often should I water Calathea?
Calathea plants generally do not need a lot of water and should only be watered when the top 1-2 inches (2.5-5 cm) of the soil is dry. Generally, that means that you should water your Calathea about once a week.
However, this can change based on a few factors. If your home is particularly dry or the soil is especially sandy, you may need to water your Calathea a bit more often. Conversely, on hotter days, you may find that your plant absorbs more water and needs to be watered more frequently.
To get a better sense of how often you should water your Calathea, check the soil with your finger every few days and adjust your watering schedule accordingly.
How do you know if Calathea needs water?
Knowing when to water your Calathea can be tricky as it’s easy to overwater and cause root rot. The best indicator is to feel the top of the soil. If the soil is dry and powdery, it’s time to water. It’s important to water until the water comes out of the bottom of the pot and onto the saucer, devoid of any standing water.
You can also wait until the leaves start to curl, which is a sign of drying out. Similarly, if they start to look droopy, it could also be a sign of needing more water. A lack of moisture can cause leaves to yellow and drop off, so be sure to manage the right balance.
Additionally, if the leaves start to look dull, wipe them with a damp cloth and mist the leaves with water to get the shine back.
Why are Calathea leaves curling?
Calathea leaves curling is usually caused by a few different main problems:
1. Too Much or Too Little Water: If a Calathea is getting too much or too little water, its leaves will start to curl up. The key to making sure your Calathea gets the right amount of water is to only water the plant when the top inch or so of soil is dry.
Additionally, make sure you are watering with room temperature distilled water or rainwater.
2. Low Humidity: Calatheas thrive in higher levels of humidity, so dry air can also cause the leaves to curl. To make sure your plant is getting enough moisture, you can spray it with filtered water in the mornings and use a humidifier.
3. Temperature Stress: Calatheas prefer to stay in temperatures between 65-78°F at night. If they are exposed to temperatures lower or higher than this they will start to curl up. Additionally, avoid direct drafts of heat or cold.
4. Too Much Fertilizer: Too much fertilizer can cause a Calathea’s leaves to burn, which will lead to curling. Make sure you are only fertilizing your Calathea once a month, with a half-strength liquid fertilizer.
Fixing the underlying issue should help your Calathea leaves uncurl. If the issue is persistent, try pruning off any damaged leaves as well.
Why are the leaves on my Calathea turning brown?
The leaves on your Calathea turning brown could be caused by several different factors. It could potentially be due to environmental stressors such as direct sunlight, inconsistent watering or inconsistent humidity levels.
Calatheas require consistently Care to thrive with indirect lighting or partial shade, evenly moistened soil, higher humidity, and minimal fertilizing. If temperatures drop below 65 degrees Fahrenheit or exceed 85 Fahrenheit, the leaves can start to turn brown.
Additionally, brown leaves can indicate that your Calathea is receiving too much nutrients from fertilizer and the excess is burning the leaves. Lastly, inadequate air circulation can also cause the leaves to brown.
To fix the issue, move your plant to a well-lit area that doesn’t receive direct sunlight and ensure that the temperature is monitored and not dropping under 65 Fahrenheit or exceeding 85 Fahrenheit.
Additionally, make sure that you provide consistent water to ensure that the soil does not dry out, either underwater or mist it to allow for more adequate humidity. Lastly, only use a light fertilizer at half strength and adjust the feeding schedule to seasonally, 3 times a year.
Should I cut off brown Calathea leaves?
When it comes to brown leaves on Calathea plants, it is important to assess the cause before making any decisions. In most cases, brown leaves on a Calathea can be the result of underwatering, overwatering, increased levels of light, or mineral accumulation.
If the brown leaves are due to underwatering, the best way to fix the issue is to increase the moisture levels of the soil and reduce light exposure. If the issue is a result of overwatering, you should reduce the amount of water given to the Calathea, and the brown leaves should soon fall off on their own.
Additionally, if the brown leaves are due to increased levels of light, try relocating the plant to an area with less sunlight. Finally, if mineral accumulation is the cause of the brown leaves, it may be necessary to repot the Calathea or flush the soil with filtered water.
In some cases, cutting off the brown leaves may be Draconian, as this may leave gaps in the foliage or cause the plant to become lopsided. Furthermore, the plant may struggle to replace the leaves and be more exposed to pests and disease.
As such, it is best to assess the cause of the browning leaves before making any drastic decisions.
Can I cut the brown tips off my Calathea?
Yes, you can cut the brown tips off your Calathea. It is important to be aware that brown tips are usually an indication of a cultural issue, so it is best to identify and address the problem before trimming off the affected leaves.
Typical causes of brown tips include incorrect watering, too much direct sunlight, not enough humidity, or fertilizer burn from overfertilizing.
To address the issue, make sure you are watering your Calathea when the soil is dry and avoid overwatering. It may be beneficial to increase the humidity around your plant either by misting with a spray bottle, placing a humidifier near your plant, or placing the pot on a tray filled with wet pebbles.
If you are fertilizing your plant, make sure to follow the product’s instructions for proper dilution and frequency and avoid fertilizing in the winter months when plant growth slows down. Properly address the cause of the brown tips before trimming them off.
Trimming off the affected parts of the leaves can also be done, although it’s unideal, as it can cause stress on the plant and leave unsightly cuts on the leaves.
Will Calathea leaves grow back?
Yes, Calathea leaves will grow back with proper care! The exact time it takes for a Calathea leaf to regrow depends on the species, but generally it takes between 3-6 months for a new leaf to form. To ensure optimal growth, Calatheas require bright indirect light, high humidity, a moist but well-draining soil, and regular fertilization.
Watering thoroughly and allowing the soil to dry between waterings will also help encourage the regrowth of new Calathea leaves. Additionally, provide adequate fertilizer to your Calathea to ensure your plant is receiving all the nutrients it needs for re-growth.
By following the proper care guidelines, you will be well on your way to enjoying a full and happy Calathea plant with lots of new leaf growth!.
How do you bring a Calathea back to life?
If your Calathea is looking a bit worse for wear, fear not – with a bit of attention it can easily be brought back to life! Start by checking the plant’s watering needs and make sure the soil is neither too wet nor too dry.
Calatheas prefer moist but well-drained soilless potting mix. To maintain proper moisture levels, aim to water your Calathea once a week. The water should be room temperature and be at the soil level with excess water draining away.
Additionally, maintain a humid environment, as Calatheas do not do well in dry conditions. Keep the plant in bright, indirect sunlight and make sure to rotate it every once in a while to ensure even growth.
Finally, provide plenty of plant food. A balanced liquid houseplant fertilizer can be applied every one to two months. With the right care, you can easily bring your Calathea back to life!.
