Plant Care Guide for Calathea Roseopicta Marion《竹芋》
-
Light
Thrives in bright indirect sunlight to partial sunlight. It can tolerate lower light conditions but may experience slower growth and less vibrant leaf colors. Avoid direct sunlight, which can cause the leaves to scorch and lose their distinctive patterns.
-
Soil
Use a well-draining, peat-based potting mix with added perlite or sand to improve aeration.
-
Water Requirement
Keep the soil consistently moist but not waterlogged. Use room-temperature water to avoid shocking the plant. Calathea plants are sensitive to chemicals in tap water, so using filtered or distilled water is recommended.
-
Temperature
Ideal growing temperatures are between 18℃ to 27℃. Keep it away from cold drafts and sudden temperature changes.
-
Humidity
High humidity is essential for Calathea. Aim for a humidity level of 60% or higher. Dry air can cause the leaf edges to brown and curl.
-
Fertilizer
Fertilize lightly during growing season. Fertilise every 4 to 6 weeks during the growing season.
-
Caution
Regularly remove any yellowing or damaged leaves to maintain the plant’s appearance. Pruning is generally minimal, as Calathea does not grow very large.
