Mouse-ear chickweed general information

Mouse-ear Chickweed

Mouse-ear chickweed is very common in fine turf, as it will tolerate very close mowing

Mouse-ear chickweed or Mouse-ear as it is also known is a short lived perennial weed that is very common in intensively managed turf and luxury lawns. It thrives in moist soils that suffer from poor drainage, but can also withstand hot, dry conditions too. It can also tolerate shade.

It forms a dense mat that can easily tolerate very low mowing heights, however, it can reach a height of nearly 30cm if it is left undisturbed.

Mouse-ear

It has a shallow fibrous root system and new plants form from roots, forming from nodes of the stems. It also reproduces from seed and it blooms continually during the summer months. The plants develop very quickly from seed, and this weed can spread very quickly in a relatively short period.

Mouse-ear chickweed has various medicinal uses, it can be used to soothe skin irritation, cuts, eczema and rashes and contain a rich source of vitamins.

Mouse-ear Chickweed leaves

Mouse-ear chickweed leaves are tiny and covered in fine hairs

The leaves are opposite and dark green in colour, with the surface being covered in short hairs. They are oval or lanceolate shaped and typically measure between 10 – 20mm long and 3 – 8mm wide, however, in fine turf they are often smaller.

Mouse-ear chickweed roots

The root system is shallow and fibrous

Prevention and control of Mouse-ear chickweed

Encouarage a healthy sward with good turf management practices to reduce the opportunity of weeds invading. Weeds are likely to be more troublesome on neglected turf, where grass coverage is generally thin and weak.

Reducing the shade may help prevent this weed from establishing.

Improve the surface drainage with regular aeration to help reduce the establishment of this weed.

Removing this weed by hand can be an effective way of controlling mouse-ear chickweed, especially if the infestation is not severe.

It the infestation is widespread then a selective weed killer may be the best option. Ideally only treat the infected areas to keep chemical usage down to an absolute minimum. Mouse-ear chickweed is susceptible to most selective herbicides and a single treatment should be enough for complete control.
