Calathea sanderiana, also known as the Rattlesnake Plant, is a beautiful foliage plant loved for its unique leaf patterns and vibrant colors. It belongs to the family Marantaceae and the genus Calathea.
Calathea sanderiana has a preference for higher temperatures. It thrives in temperatures ranging from 18 to 24 degrees Celsius. Avoid exposing it to temperatures below 13 degrees Celsius as it can negatively impact its health.
The Rattlesnake Plant prefers bright but diffused sunlight. It is suitable for placement in a well-lit indoor location without direct sunlight. Excessive exposure to intense sunlight can cause leaf yellowing or burning. If grown outdoors, choose a partially shaded or shaded spot to protect the plant from excessive exposure.
The watering frequency and amount depend on the season and environmental conditions. Calathea sanderiana likes to keep the soil moist but not overly wet. Typically, watering two to three times a week during the growing season is appropriate. In winter or cooler seasons, the watering frequency can be reduced, but do not let the soil completely dry out.
Fertilizing is important for the growth and leaf patterns of Calathea sanderiana. It can befertilized monthly using indoor plant fertilizer. Follow the instructions on the fertilizer packaging for proper application and avoid over-fertilization, which can harm the plant.
Pruning Calathea sanderiana helps control its shape and promotes new growth. Trim any yellow, diseased, or damaged leaves, and regularly trim excessively long leaves. Use clean and sharp scissors for pruning and ensure good ventilation for the plant after pruning.
Other considerations include maintaining moderate humidity and temperature. Calathea sanderiana prefers a humid environment and can benefit from increased air humidity through misting or placing it on a tray with moist pebbles. Additionally, be mindful of avoiding direct exposure of the leaves to cold drafts or hot air, as it can cause damage to the plant.
