Planting Instructions

1. Amend soil the fall before planting with 20 lbs of 10-20-10 fertilizer or mature compost per 1,000 sq ft, worked 6 inches deep.
2. Select a full-sun site with well-drained soil. Medium to light soils are best; heavy clay loam also works.
3. In early spring after last frost, dig trenches 5 inches deep and 6–8 inches apart in rows.
4. Add 2 lbs of 0-20-0 superphosphate per 50-foot row; cover with 1 inch of soil.
5. Soak crowns in lukewarm water for a few minutes before planting.
6. Set crowns 18 inches apart, buds pointing up; spread roots over trench sides.
7. Fill with 3 parts topsoil and 1 part compost. Do not compact.
8. Water thoroughly after planting.
9. Mulch 4–8 inches after emergence to suppress weeds.
10. Side-dress with mulch each fall; cut back dead fern in early spring.
11. Begin harvesting 7–9 inch spears by snapping at the base once crowns are established.
