Lady Fern is easy to grow and thrive in moist, well-drained soil. Plants can tolerate dry soil conditions better than most other ferns. Lady ferns grow best in shaded areas of the garden but can handle sun if soil is constantly moist. They grow to be 1 to 3 feet high and have a plant spread of 1 to 2-1/2 feet.
