Can you plant yarrow in pots?
Grow yarrow in a container by itself or with other plants to add long-lasting color to a sunny deck, patio or apartment balcony. Design a waterwise parking strip with yarrow and drought-tolerant companions. Yarrow spreads quickly by rhizomes. Divide every 2 to 3 years in spring or fall to avoid overcrowding and to reinvigorate plants that begin to look matted and untidy.
