Planting Instructions for Osmunda (cinnamon, interrupted, royal fern):

Light:  Part shade to full shade Moisture:  Consistently moist to wet
Soil:  Humus-rich with regular moisture pH:  Slightly acidic
Planting Depth:  Top of crown at soil level, mulch lightly Spacing:  18 to 24"

Upon arrival:  Unpack box and check that you have everything on your packing list. Osmunda should be just slightly moist when packaged. Plant everything within a day or two.

Soil/Location:  Plant cinnamon, interrupted, and royal ferns in part shade to full shade in humus-rich, moist to wet soil. Edges of swamps, marshes, ponds or streams, or any areas that hold a lot of moisture are ideal. Avoid areas that get too dry during the growing season or they will struggle.

Moisture:  Osmunda is native to swamps, marshes, and wet forests where they grow tall and majestic. Keep them well watered at all times for the best growth.

Spacing:  18 to 24"

Depth:  Plant your ferns with the top of the crown just about even with the soil level and then topdress with a light covering of compost or mulch.

General Instructions:  Enrich your garden with generous amounts of compost or peat humus. Plant the roots at the depth listed, then water in good. Your ferns will start sprouting as soon as the soil warms and generally won't need extra water while dormant unless the soil gets very dry. Once they have sprouted they enjoy being watered a few times a week, as needed, and should be given extra water during dry periods. Most ferns are fertilizer (salt) and chemical sensitive, so avoid chemical fertilizers and insecticides and instead improve the soil with organic matter to help them grow better.

Landscape Uses:  Use these ferns as a backdrop in larger gardens. Plant them with hostas, pulmonarias, tiarella, and tricyrtis, or in the bog garden with ligularia, rodgersia, and other large, bold moisture loving perennials. They will reach their best potential when planted in wet conditions near lakes, ponds, and streams.
