Dryopteris erythrosora - 'Autumn Fern' aka Japanese Shield Fern

Overall Description

Dryopteris erythrosora, commonly called Autumn Fern or Japanese Shield Fern, is an arching, evergreen (semi-evergreen in cold winter climates) fern that grows in a vase-shaped clump to 2' tall and equally as wide. It is native to woodland hillsides and mountain slopes in Japan, China and Taiwan. New fronds unfurl in a wide range of various tones of orange, bronze, copper, yellow, and occasionally reddish hues as well. Foliage gradually matures into a nice medium to dark green and forms triangular bi-pinnate fronds up to 2 ft long.

Autumn Fern, as with most fern varieties, thrives in shady location with cool, damp soils.........and especially loves soils with lots of organic matter / humus. Prefers slightly acidic soil pH, and will not do well if planted in a location that is allowed to dry out completely. Needs to have a nice little shady, moist area where soil temps can remain a little cooler.

Uses include shade garden plantings, container gardening on shaded porches & decks, around entrances & around bases of larger trees that would provide a shade canopy. Can also be mass planted in shaded woodland areas for understory naturalization.

--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
