What is Marsh Fern?

Growing Marsh Ferns
Marsh ferns thrive in boggy to moderately wet regions. Growing marsh ferns in the home landscape will require a location that mimics such conditions or constant irrigation. Sandy, acid soil provides the best medium, but this adaptable plant can survive in almost any medium as long as it is moist but not in standing water.
Try growing marsh ferns around the edges of a water feature or pond, or along a swale where water collects in the rainy season. They are relatively unbothered by disease or pests. Remove any spent foliage as it occurs for best appearance. The plants pair well with other native species and ferns, such as Epimedium and marsh marigolds.
Marsh Fern Care
In cold climates with sustained freezes, apply mulch, such as organic bark or straw, around the plant’s crown to protect the root zone. You may want to cut off the spent fronds and make a teepee around the top of the plant. This cocoons it and adds extra protection. Remove the foliage and mulch in early spring so new fronds can break through.
Ferns generally need no fertilization in average soil. If your soil is poor, use a balanced all-purpose food, diluted by half in early spring. Otherwise, marsh fern care couldn’t be easier. The plant has a moderate growth rate and regal appearance which is a boon to any garden.
