Yarrow (Achillea millefolium)
Yarrow flowers from June to August and often into October and its clusters of small, white flowers are insect pollinated. The perennial’s roots penetrate up to 20cm deep and branched rhizomes help plants to spread at a rapid rate. It grows on most types of soils, having a high tolerance for dry or infertile types, and it can often be found on sports fields and heathland golf courses. Its strongly scented, fern-like leaves appear on mature plants.
Treatment
A thick sward and fertile soil will prevent yarrow establishing in the first instance. Yarrow may be removed by hand so long as great care is taken to ensure all the roots are completely taken out. Use Greenor , Crossbar or Super Selective Plus when the weed is actively growing for maximum efficacy.
