The Blue Star fern likes to have moist soil but not soggy. Best to check the soil weekly, and if the top inch of soil feels dry, give this plant a water. Ferns usually live in the forest and will tolerate low light levels, however will thrive in indirect sunlight and ideally in a humid environment. Bathrooms will be ideal for this plant. If you live in a hard water area your Blue Star Fern will benefit from room temperature rain water or distilled water if possible.
