Care Guide

- Fertilization: Feed the plant with a balanced, water-soluble fertilizer every two weeks during the growing season.
- Soil: Use a well-draining potting mix that is rich in organic matter.
- Sunlight: Place the plant in bright, indirect light. Avoid direct sunlight, which can scorch the fronds.
