Hawkweeds are herbaceous perennials with fibrous roots and strong rhizomes. All but one invasive species has yellow flowers. Flowers resemble dandelions, and form at the top of long, hairy or hairless stems, also in compact rounded or loose, panicle-like clusters. Invasive Hawkeye species can be hard to differentiate as many characteristics cross over. For more information on how to identify the differences between native and invasive species, visit the Hawkweed Identification Key website. Hawkweed plants can reproduce by seeds, vegetatively by stolons, rhizomes and adventitious root buds.

Hawkweeds can be mowed or string trimmed, though disturbing the soil may allow the plant to spread further. Mowing and string trimming should be done before the plant has gone to seed or even before it blooms. Hawkweeds can be removed by hand or with tools, but great care is required to ensure no roots or stolons are left behind. Reducing large stands with herbicides can be effective, and will make mechanical control methods more manageable.
Hawkeye should not be combined with other green waste. Notify the attendant when bringing to green waste facilities to see if they have an area where it can be disposed. For green waste facilities put contents into a clear plastic bag. If there is not a location for it to be disposed, contents can be put into a black plastic bag and put it in your garbage bin or take to your local garbage disposal facility.
