Care
Black Cohosh prefers well-drained, rich soil. Keep the ground consistently damp but not saturated. It benefits from occasional feeding with a balanced fertilizer. Remove dead foliage to encourage new growth and protect it from harsh winter conditions.
Plant Reproduction
Black Cohosh spreads by dividing its rhizomes in the spring or fall.
Planting bare-root perennials is best in any season if they are dormant; we only sell dormant plants. Planting them year-round is also excellent if you can get dormant perennials. When your bare-root perennials arrive, soak the roots in water for a few hours to rehydrate them. Lant by digging a hole wide enough to spread the roots comfortably and deep enough to place the top portion crown (where the roots meet the stem) at or slightly above ground level. Position the plant in the hole, backfill with native soil, and gently firm the soil around the roots—water well after planting to settle the soil around the plant and eliminate air. Apply a 2-3 inch layer of mulch to keep weeds at bay and moisture locked in, keeping the mulch away from the crown. Irrigate plants regularly during the first few weeks of drought; never water in full sun, and water late in the evenings to ensure the roots are established well. Fertilize sparingly in the first year, using a balanced, slow-release fertilizer in subsequent years as needed.
