How to Care for a Rattlesnake Plant
Since this plant is native to tropical regions of Brazil, it requires plenty of warmth and moisture. It means it can’t do well in dry, cold areas.

At the same time, keep in mind that the Rattlesnake plant is very resistant to the browning of the leaves. Unlike other Calathea plants, that easily develop brown spots, this doesn’t happen so often with a Rattlesnake plant. If it does happen it is a sign that something is seriously wrong and that you need to change the care regime. Most of the time, this problem develops due to coldness and low humidity.
The best way to make your Rattlesnake thrive is to plant it in a slightly sandy soil that allows for good water drainage. Make sure to keep your plant away from direct sunlight. Too much bright light is not good for your Rattlesnake plant. It will also make the leaves fade and lose those bright markings, which may affect the plant’s appearance. The best place for a Rattlesnake plant is an indoor patio or a room in your home near a window that doesn’t get much direct sunlight.

- Soil. Your Rattlesnake plant will thrive in potting soil that is 2 parts peat and 1 part perlite. It is important to choose a potting soil that can retain some moisture while also providing good drainage. However, make sure not to use too much drainage materials because it will make the soil lose moisture quickly. You should replenish the top part of the soil in the spring months. It will allow the plant to get fertilizer properly and to benefit from all the nutrients.
- Light. This plant needs bright light but not direct light. As such, it’s best to keep it in a bright spot in a room that is away from direct sunlight.
- Temperature. Rattlesnake plant thrives in temperatures between 65 degrees F and 75 degrees F (18 to 24 degrees Celsius). Make sure never to keep your Rattlesnake plant in a room that has a temperature lower than 60 degrees F (15 degrees Celsius). You should also make sure to avoid cold drafts and any sudden temperature changes.
- Humidity. This is a plant that loves moisture, just like other varieties of Calathea. You can try misting the leaves to improve humidity but Rattlesnake plants actually prefer a tray with water. Simply place a tray with pebbles and water under the pot. It will help holding the moisture and increase the humidity levels. If this doesn’t work, consider investing in a humidifier.
- Watering. You need to water your Rattlesnake plant frequently during the growing season, from May to August in particular. It is important to keep the soil moist, but never allow your plant to sit in water. Cut the watering down during the winter months. Only water when the top of the soil becomes dry to the touch.
- Fertilizing. Make sure to fertilize your plant regularly with a balanced liquid fertilizer. Feed your plant once per month in the period from April to August. Fertilizer will improve the health of the foliage and make the leaves stronger and more impressive.

After repotting the segments, make sure to water properly but then give segments some time between watering to develop a new growth. Wait until there is new growth to start watering again.
