Deadheading spent flower heads is recommended to promote extended blooming. For best growth, cut stems back to a couple of inches above the soil after the first killing frost. Apply a thin layer of compost each spring for more vivid color, followed by a 2-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than one inch per week. Requires good drainage. Divide plants every 3 to 4 years as new growth begins in the spring, lifting plants and dividing them into clumps. Yarrow is easily dividable by simply digging up a large quantity and shaking loose into clumps. Ideally, this is done in springtime though yarrow will tolerate propagation virtually anytime.

No unusual shipping concerns for this plant.
