Almost every landscape has shady areas, and ferns are a great group of plants that are perfect for those shady spots. Early spring is an excellent time to plant ferns in a landscape; it allows them to settle in and establish before the heat of summer arrives. So, if you've got some shady areas and you think ferns would work there now is the time to get them in the ground.
