Origin
Calathea sanderiana, also known as Maranta sanderiana, originates from the tropical rainforests of South America, mainly Brazil. This plant species belongs to the Marantaceae family and is primarily native to shady, humid environments.
Characteristics
Calathea sanderiana is known for its striking leaves, which grow on long, slender stems. The upper side of the leaves is dark green, while the underside is purple-red, decorated with a pattern of fine, lighter-colored lines. A characteristic feature of this species is its unique rhythm: it opens its leaves during the day and closes them at night – a phenomenon known as nyctinasty (sleep movement).
Care
For optimal growth, it is important to place Calathea sanderiana in a location where it is not exposed to direct sunlight but still receives plenty of light. The plant likes high humidity and requires regular watering to keep the soil slightly moist. For fertilization, you can use a general houseplant fertilizer, which should be applied once a month during the growing season. It is important to avoid overwatering, as this can lead to root rot.
Care mistakes:
1. Tap water
Calatheas are very sensitive to the fluoride and chlorine found in tap water.
-
The mistake: Watering with fresh tap water.
-
The symptom: The edges of the leaves turn brown and dry out.
-
The solution: Use rainwater, distilled water, or at least let tap water stand for 24 hours before watering the plant.
2. Air that is too dry
As a tropical plant, Hungarian homes (especially during the heating season) are too dry for it.
-
The mistake: Placing it near a radiator.
-
The symptom: Curling leaf edges and a wilted appearance.
-
The solution: Place the pot on a tray filled with pebbles and water (so that the bottom of the pot does not touch the water), or use a humidifier.
3. Direct sunlight
Although it loves light, its leaves are paper-thin and fragile.
-
The mistake: Placing it on a south-facing windowsill.
-
The symptom: Faded colors, yellow spots, or specific burn marks on the leaves.
-
The solution: A bright spot, but with filtered light (for example, behind a thin curtain).
