If planted outdoor, plant the foxtail fern in a lightly shaded area to avoid the hot afternoon sun. If planted indoors, keep the plant in an area receiving bright light and direct morning sun in winter.

The foxtail fern prefers soft light because too much strong and direct light can burn the leaves of the plant. In some areas, they can grow in full sun.


Foxtail ferns grow best in slightly acidic soil. They can do well in many varieties of soil, as long as the soil mixture is well-draining. A well-draining soil mixture prevents the plant from problems with root rot.


The Asparagus plant is also known as emerald fern and ponytail fern because it benefits from immersion for thorough watering. In between watering, let the top 3 inches of the soil dry out.
