How to care for ferns:
Lighting: Although most ferns grow in moist shady places like forest floors, this does not mean that they need no light. Their normal situation in the wild is dappled light, and if the light level in the home is too low, you will see poor growth and yellowing fronds.
Water: Most ferns like an evenly moist soil with regular waterings. Allowing the soil to dry out between waterings stresses these plants.
Temperature: An individual fern’s place of origin and adaptability will determine how high or low of a temperature the fern needs. Most ferns don’t like the cold. Ferns from tropical regions truly appreciate temperatures between 60 - 70 degrees F. Those from more temperate regions enjoy temperatures between 50 - 60 degrees F.
