Care Essentials
Get to Know Your Rattlesnake Plant
Watch the humidity — a little extra moisture in the air goes a long way with this plant.
Light
medium to bright indirect
Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.
💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.
Watering
every 7-10 days
Water when the top 1-2 inches of soil feel dry. Adjust with the seasons — less in winter, more in summer.
Humidity & Temperature
Appreciates some humidity but adapts to average home conditions. Brown tips in winter? Your air might be too dry — a light misting helps.
Prefers moderate temperatures (60-80°F). Keep away from radiators and intense afternoon sun windows.
Soil
Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

Why do my Rattlesnake Plant leaves have brown tips?
Brown leaf tips and edges on a rattlesnake plant (Calathea lancifolia) come from two causes the book names for the broader Calathea group: the chemicals in ordinary tap water, and indoor humidity that is too low — both of which scorch the leaf margins even when the rest of the plant looks healthy

Cause
Brown leaf tips and edges on a rattlesnake plant (Calathea lancifolia) come from two causes the book names for the broader Calathea group: the chemicals in ordinary tap water, and indoor humidity that is too low — both of which scorch the leaf margins even when the rest of the plant looks healthy.
Solutions
- Switch to distilled water or rainwater when watering, since calatheas are sensitive to the chemicals in tap water.
- Raise humidity around the plant by placing it near a humidifier, on a pebble tray, or by frequent misting, and keep it within 65–77°F (18–25°C) away from drafts and indoor heating sources.
Prevention
Use only distilled water or rainwater, keep humidity high with misting or a pebble tray, and never let the rattlesnake plant sit next to radiators or drafty windows so the leaf margins stay clean.
Why is my Rattlesnake Plant wilting?
Drooping or visibly rotting stems on a rattlesnake plant (Calathea lancifolia) trace to two conditions the book names for the broader Calathea group: soil kept wet enough that the plant sits in water, and exposure to temperatures outside the 65–77°F (18–25°C) range — cold drafts and chilly rooms are the usual trigger

Solutions
- Let the top 2" (5cm) of soil dry out before watering again, and always pour off any excess so the pot is never sitting in standing water.
- Move the rattlesnake plant away from drafty windows and radiators, and keep the room between 65–77°F (18–25°C) so cold air does not rot the stems.
Prevention
Water only when the top of the soil has dried, drain fully after every watering, and place the rattlesnake plant in a warm spot with stable temperatures and away from cold drafts.
Pests (1 topics · 1 cases)
Why does my Rattlesnake Plant have spider mites?
Spider mites are the pest the book singles out as the most common on the broader Calathea group that includes the rattlesnake plant (Calathea lancifolia); they take hold on the foliage when indoor humidity is low and the air is dry, which is the same condition that already stresses a rattlesnake plant

Cause
Spider mites are the pest the book singles out as the most common on the broader Calathea group that includes the rattlesnake plant (Calathea lancifolia); they take hold on the foliage when indoor humidity is low and the air is dry, which is the same condition that already stresses a rattlesnake plant.
Solutions
- Wash all the leaves and stems with a gentle stream of water, then wipe them down with a mixture of castile soap and water (1 Tbsp. (15ml) castile soap to 3 oz. (1 L) of water), and rinse again with water.
- Avoid neem oil on this plant — the book states neem oil does not agree with calatheas and will cause the leaves to turn yellow and fall off.
Prevention
Keep humidity high with misting, a humidifier, or a pebble tray, check under the rattlesnake plant's leaves often for mites, and use only the castile-soap wash if an outbreak starts so the foliage is not damaged.
