Description
While Lady Fern may look high maintenance, it's incredibly easy to grow in moist and well-draining soils. It's deer, rabbit, and disease resistant, which means the fronds keep their appeal all season long. It naturalizes well when grown in optimal conditions (even in clay and wet soils), making it a great choice for nearly every gardener.

How to Grow
Light: Part-sun (4-6 hours sun) to shade (< 4 hours sun). It can handle more sun if the soil is moist, but the fronds risk burning.
Water: Tolerates more soil dryness than some other ferns, but the soil must not be allowed to dry out.
Spacing: 1.5 – 2.5 ft apart
Fertilizing: Annual application of compost. Avoid any inorganic fertilizers, as they may burn the roots.
Winterizing: Leaves should be trimmed to the ground in late fall or early spring.
Maintenance & pruning: Very low maintenance. Trim leaves in the late fall or early spring. Plants can be propagated by division in spring every few years as desired.
Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:
