Planting Instructions for Asplenium (Hart's-tongue fern):

Light:  Dappled shade to full shade Moisture:  Average
Soil:  Humus-rich, moist but sharply draining pH:  Neutral to alkaline (7.0 - 8.5) but adaptable
Planting Depth:  Roots/crown at soil level Spacing:  15 to 18"

Upon arrival:  Unpack box and check that you have everything on your packing list. Asplenium should be just slightly moist but not wet when dormant. Plant everything within a day or two.

Soil/Location:  Plant Asplenium in dappled shade to full shade in loose and airy, humus-rich, very well-draining soil. It prefers alkaline conditions for best growth and appearance so you may want to incorporate some lime, crushed limestone, or oyster shells into the planting area, and add compost or peat humus to enrich and loosen the soil, if needed. Avoid areas with intense heat or afternoon sun and avoid areas that stay wet, especially if it remains wet in the spring

Moisture:  Asplenium is native to rocky limestone where it is cool and moist but sharply drained. Water lightly, though it is rarely needed, but let them dry out between watering and never keep them wet.

Spacing:  12 to 15"

Depth:  Plant your ferns with the top of the roots/base of the crown at soil level. Mulch lightly around the crown so the roots don't become exposed but don't bury the base of the plant itself as that can promote rot.

General Instructions:  Enrich your garden with generous amounts of compost or peat humus and if needed incorporate some lime, crushed limestone or oyster shells into the planting site. Plant the roots at the depth listed, then water in once lightly. Your Asplenium will start sprouting as soon as the soil warms and generally won't need any extra water while dormant. Once they have sprouted they don't mind being watered once a week or so, if it is even needed, allowing the soil to dry between watering.

Landscape Uses:  Hart's-tongue fern has unique leathery fronds that add a compact vertical accent to the woodland garden. Combine it with hostas, Actaea (cimicifuga), Pulmonaria, Tiarella, and other shady perennials, or plant it between rocks or at the base of trees and shrubs for a more natural appearance.

Hart's-tongue fern is usually listed as Asplenium scolopendrium but it is also known as Phyllitis scolopendrium and Scolopendrium vulgare.
