Growing and Maintenance Tips

Yarrow is one of the easiest perennials to grow and is a good choice for beginners. All it needs is full sun and well-drained soil. It thrives in average to poor soil and is drought tolerant once established. Plants grown in rich soil tend to be tall and floppy. After the flowers have faded, cut the plant back by half. This will likely stimulate a second flush of blooms in late summer.
