Maintenance
Yarrow has so many seeds in their flower heads! Cut once the first summer flush is spent, then leave 1/3 of the seed heads for the birds through the winter. This is a drought-tolerant plant and will spread rapidly if there is an abundance of water.
Young native plants need to be consistently watered 2-3 times a week until after their first fall. After that, they will set their tough root systems through the winter, which makes it possible to live in the harsh, arid climates
