Autumn Hawkbit

Leontodon autumnalis

autumn hawkbit
General - Autumn Hawkbit is a perennial weed that grows in a rosette formation, it is generally not a serious problem on mown lawns and turf.

It is more common in longer grass such as roadside verges and meadows.

Leaves - The leaves are very narrow with deep lobes, however the leaves can vary between plants and can sometimes be confused with those of Cats Ear.

Flowers - Autumn Hawkbit flowers are similar to those of Dandelion but smaller in size. The yellow flowers can be seen between July and October.

Roots - Autumn Hawkbit has a tap root.

Habitat - Autumn Hawkbit can tolerate a wide range of conditions, especially poorly drained soils.

Cultural Control - The weed can be physically removed by hand weeding, taking great care to remove all of the root.

Encourage a thick sward of grass to prevent any weeds taking advantage of any weak or thin areas on the lawn.

Chemical Control - If chemicals are to be used spot treatment is an ideal option for Autumn Hawkbit control.

Choose a selective weed killer that contains 2,4-D and mecoprop-p, a further application may be necessary about 6 weeks later to control this weed.

Selective weed killers should be applied when the weeds are actively growing usually between April and September.
