DETAILS

Care Instructions
Pityrogramma calomelanos thrives in bright, indirect light and prefers moderate temperatures. It requires high humidity and should be watered regularly to keep the soil evenly moist. Avoid direct sunlight as it can scorch the fronds. This fern can be grown both indoors and outdoors, provided the conditions are suitable.
Soil
This fern prefers well-draining loamy soil that retains moisture without becoming waterlogged. A mix of peat, perlite, and loam works well. Ensure the soil is slightly acidic to neutral in pH.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize monthly during the growing season to support healthy growth. Reduce feeding during the dormant period, if applicable.
Repotting
Repot Pityrogramma calomelanos every 1-2 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, shake off excess soil, and place it in the new pot with fresh soil mix.
Propagation
Propagate this fern through division. The best time to propagate is during the growing season. Carefully separate the rhizomes and plant them in individual pots with a suitable soil mix. Keep the new plants in a humid environment until they establish.
Pruning
Pruning is generally not required for Pityrogramma calomelanos. However, you can remove any dead or damaged fronds to maintain the plant's appearance and health.
Toxicity
Pityrogramma calomelanos is not known to be toxic to pets or humans. However, it is always a good practice to keep plants out of reach of pets and children to avoid any accidental ingestion.
Additional
Ensure the plant is kept in a humid environment, especially if grown indoors. You can use a humidity tray or mist the plant regularly to maintain the required humidity levels. Regularly check for pests such as aphids or scale insects and treat them promptly.
