Rattlesnake, brown spots are a terrible sight and can be a cause for concern. These spots can be attributed to factors such as low humidity, excessive exposure to sunlight, or inadequate watering practices.Rattlesnake Plant Brown Spots

Read on to discover valuable insights on what to do when spots appear on your plant and how to rectify this problem to ensure your plant’s well-being.

What Are the Reasons That the Rattlesnake Has Brown Spots?

The reasons that the rattlesnake has brown spots is that the plant is that it has poor soil conditions or low humidity, and it may be under too much light. In addition, it can have sap-sucking insects, facing diseases, placing excessive amount of fertilizer and poor water quality.

Brown spots or even brown tips on the rattle snake plant leaves can be caused by overwatering, poor-quality water, excessive sun exposure, fungal diseases, and pest infestations. To address the problem effectively, you need to be able to pinpoint it first and know the key reason for the problem.

– Poor Soil

It’s not just about the amount of water you give to your rattlesnake plant but also the quality of the soil that it would be living in. If the potting soil is too compact, it can lead to plants becoming waterlogged, and with the wrong type of soil, you will see how the plant will still have water standing on top or even at the bottom.

You must consider how this plant is one that has roots that like to breathe, and compact soil doesn’t allow for proper airflow or drainage. It’s like trying to run a marathon with shoes two sizes too small—uncomfortable and suffocating. As a result, the plant will begin to have excessive water stuck along the roots.Brown Spots on Snake Plants

– Low Humidity

Rattlesnake plants have a humidity craving, and so they prefer their surroundings to be a little moister, with humidity levels around 50 percent, compared to the average humidity in your home. As they face low humidity, the leaves will begin to change their color and look weakened.

If your Calathea lancifolia isn’t getting the right amount of humidity, it can start to show its discontent by developing unsightly brown spots on its leaves. It’s like a cry for help, signaling that it feels parched and needs moisture. If this issue persists, things can only go from bad to worse, with the leaves turning brown and crispy, and the plant’s growth coming to a halt.

It’s a stressful situation for your plant; we all know that stress leads to vulnerability. A stressed-out rattlesnake plant becomes a prime target for infestations and diseases. It’s like the weakened immune system of a tired traveler falling prey to all sorts of nasty bugs.

– Too Much Light

Low light conditions may occasionally be the culprit when it comes to brown spots on Calathea leaves, although it is not as prevalent as excessive sunlight. This may be the stage before the leaves are subjected to having sunburn; as a result, they will develop brown dots on the leaves.

If your plant currently resides in a dimly lit area, it might be worthwhile to relocate it to a spot with more sunshine. Giving your plant access to brighter light can help improve its overall health and minimize the occurrence of brown edges.

Remember, finding the right balance is key. While these plants aree ones that appreciate bright, indirect light, direct sun can be too intense and cause damage to their delicate leaves.

– Sap-sucking Insects

While the rattlesnakes are generally resilient to pest invasions, they are not entirely immune and may occasionally fall victim to these tiny intruders. Fortunately, most pest problems with these plants are more of a nuisance than a major threat as indoor plants seldom succumb to this threat.

Nevertheless, these pesky sap-sucking insects can leave their mark by creating small brown leaf tips where they have pierced the plant tissue with their mouth, and they will leave dark shades of spots. You have to examine the leaves and the surrounding of the plant to check the infestation of the bugs that are attacking the plant.

Although these spots may be unsightly, addressing the pest issue promptly and implementing appropriate control measures can help protect your plant and restore its pristine beauty. Remember to keep a watchful eye for any signs of pests like spider mites and take action to ensure your plant remains healthy and vibrant.

– Diseases

Among the various diseases that can lead to brown spots on the plant, leaf spot disease takes the spotlight as the most prevalent culprit. This troublemaker is caused by fungal or bacterial pathogens, which tend to thrive in warm and humid environments. The most prominent overwatering-triggered disease is the deadly root rot and the degree of the risk that it has reached.

Dealing with spot disease can be quite a challenge, as it can be resistant to treatment. That’s why the best approach is to focus on prevention, taking proactive measures to shield your beloved rattlesnake plant from these troublesome diseases.

– Too Much Fertilizer

While providing nutrients is important for the plant’s growth, too much fertilizer can lead to an imbalance and damage its delicate root system. When these rattlesnake plants are overfertilized, the excess salts and minerals build up in the soil, resulting in a phenomenon known as fertilizer burn.

This burn that comes from the fertilizer will cause damages the roots and disrupts the plant’s ability to absorb water and nutrients properly. The brown discoloration is often a sign of fertilizer burn. The high concentration of salts in the soil draws water out of the plant cells, causing dehydration and browning of the foliage.

– Poor Water Quality

The quality of water you use to water your rattle calathea plants can have a significant impact and may even lead to brown spots. Tap water commonly used for watering plants contains chlorine, fluoride, and other additives municipal water systems add.

While intended for human consumption, these additives can be detrimental to your plant. When you water your plants with tap water containing these substances, they can accumulate in the soil over time. As a result, the roots absorb the water along with these chemicals, which can cause damage and lead to the formation of pots on the leaves.

What Are Ways to Restore Rattlesnake Plants with Brown Spots?

Ways to restore rattlesnake plants with brown spots is to stop watering the plant for a while and increase the humidity surrounding it. You should also deal with the diseases, avoid any compact soil, and provide the right light for it, avoid overfeeding it and try to adjust the temperature.Ways to Restore Rattlesnake Plants

– Stop Watering the Plant

If your plant has already begun to turn brown, you should immediately cut the water supply and observe what’s happening. This way, you can cross out the most probable cause — overwatering.

Don’t worry; it has been watered for so long, as you may see that the soil appears moist and is spongy, you’re likely overwatered your plant, and if it’s too loose and dust-like, you can begin worrying about other causes. On the other hand, you may want to repot the plant and try to resume the right watering habit, if the damage is greater.

– Increase Humidity

Insufficient humidity is another factor that can lead to the development of brown spots on rattlesnake plants’ leaves. These plants thrive in tropical environments with higher humidity. When the air around the plant becomes too dry, it can stress the leaves and cause browning and discoloration.

To address this issue, you can take steps to increase the humidity around your plant. Placing the plant on a tray filled with water or using a humidifier nearby can help create a more suitable and humid microclimate for the plant, to increase the moisture.

In addition to this, providing the right amount of humidity can create a healthier environment for your rattlesnake plant, reducing the risk of browning and promoting its overall well-being. Plus, it will buy you some time with watering and to determine if anything else is at hand.

– Deal With Disease

Fungicides can be valuable tools in addressing various issues caused by fungal pathogens. However, it’s important to note that not all bacterial spot-causing pathogens can be effectively controlled by fungicides alone and give the right plant care guide afterward.

Nevertheless, when dealing with brown dots on the rattlesnake, you can incorporate fungicides as part of a comprehensive treatment approach. By implementing preventive strategies, such as providing adequate airflow, avoiding excessive moisture, and maintaining a healthy growing environment, you can create a shield of protection around your plant, keeping those brown dots at bay.

To ensure the effective and safe use of fungicides, carefully read and follow the instructions provided on the product label. Look for a fungicide specifically formulated to address bacterial spots, as the label indicates and try to follow the right steps.

For instance, you may place some copper fungicide, as it is a commonly recommended option for tackling this type of problem and is readily available at garden centers and hardware stores. By combining the appropriate use of fungicides with other treatment measures, you can enhance your chances of successfully eliminating brown spots and promoting your plant’s health.

– Avoid Compact Soil

Opt for a well-draining potting mix that is specifically formulated for tropical plants. Look for mixes that contain ingredients like perlite or vermiculite, which help improve soil aeration and drainage, where water that is given for irrigation will drain out and not stay alongside the roots.

If you’re planting rattlesnakes in the ground, it’s important to prepare the soil properly. Incorporate organic matter such as compost or aged manure into the soil to improve its structure and drainage.

– Provide the Right Light

Choose a spot near a bright window that faces east, find a well-lit location without exposing your plant to direct sunbeams, and let its vibrant colors flourish. This allows the plant to receive gentle morning sunlight, which is less intense and won’t harm the plant.

To ensure the light is diffused and not too harsh, place a sheer curtain or blind over the window. This helps filter the sunlight, providing the plant with its preferred indirect light.

These plants are sensitive to direct light, so keeping them out of their path is crucial. Sunlight can burn the leaves and cause quite some damage. In short, placing the plant away from direct light throughout the day can safeguard it from potential problems.

– Don’t Overfeed

When it comes to fertilizing your beautiful-leaved plant, opting for organic choices like worm castings or compost can be beneficial. These natural alternatives provide nourishment without the risk of overfeeding and burning the plant.

If you prefer commercial fertilizer, applying a balanced liquid fertilizer sparingly is important. Try to be consistent and apply once a month during the spring and summer months, because this is typically sufficient to meet the plant’s nutritional needs.

To ensure you don’t overfeed your plant with long leaves, you can reduce the recommended amount of fertilizer by half. This moderation helps prevent excessive nutrient buildup in the soil, which can lead to brown dots and other issues.

By adopting these practices, you can provide your plant with the right amount of nourishment, promoting healthy growth while minimizing the risk of over-fertilization. Remember, a balanced approach is key to maintaining the plant’s well-being.

– Adjust for Temperature

Maintaining a consistent temperature range is crucial for the well-being of the plant. An environment with temperatures from 68 to 85 degrees Fahrenheit throughout the year is ideal.

Moreover, to prevent temperature fluctuations that can stress the plant, it’s essential to avoid placing it in areas prone to drastic temperature changes. Steer clear of spots near exterior doors or close to heating or cooling vents, as these can expose the plant to inconsistent and potentially harmful temperature shifts, which will ease the issue and restore it.Rattlesnake Plant Brown Spots 1

– Opt For Better-Quality Water

Distilled water is the top choice for these plants. If this water is not readily available, you have a couple of alternatives.

Filtered water or rainwater can serve as suitable substitutes for watering your plant. These options help minimize the presence of chemicals or pollutants that can potentially harm the plant.

If tap water is your only option, there’s a simple trick to make it more friendly. Allow it to sit in an open container for approximately 24 hours before watering your plant. This period allows any chlorine present in the water to dissipate, ensuring a safer watering experience for your plant.


Brown leaves can be a cause for concern, but with a proper understanding of plant care, they can be prevented and treated effectively, as below are the key points we covered:

  • Provide the plant with indirect sunlight by placing it near a bright window that faces east, while ensuring the light is diffused.
  • Increase humidity by using methods such as tray water or a humidifier. Address insect infestations promptly and take preventive measures to protect the plant from diseases.
  • When fertilizing, opt for organic options or use balanced liquid fertilizers sparingly. Reduce the recommended amount of fertilizer to avoid overfeeding.
  • Maintain a consistent temperature range between 68 and 85 degrees Fahrenheit and avoid areas with drastic temperature fluctuations.
  • Use distilled, filtered, or rainwater for watering, or let tap water sit for 24 hours to allow the chlorine to dissipate. These measures will help create a healthier environment for your plant, reduce the risk of browning, and promote its overall well-being.

By understanding the causes and taking proactive steps, you can enjoy the beauty of your rattlesnake without the worry of unsightly brown dots.
