Field Woodrush (Luzula campestris) is noticeable in a lawn in early spring. It can be easily seen as a patch of thicker-type grass, with hairy leaves that have tassel-like black and brown flowers protruding a couple of inches above the usual level of the lawn.
Some folk also know it as Good Friday Grass or Sweeps Brush. It is very common across all areas of the UK and temperate Europe.
Field Woodrush is a very short plant, rarely peeking above the mowing height of the grass.
It usually spreads in small patches, but can spread to a couple of metres across if left unchecked. Woodrush often goes unnoticed in many lawns due to the fact that it blends in with the grasses which surround it. Sometimes a keen eye is needed to even spot it.
Luzula Campestris is member of the rush (Juncaceae) family of plants.
Field Woodrush loves acidic lawns
Woodrush is most common in acidic lawns. It is most happy where lawn thatch has built up, weakening the grass and lowering the pH. Many nitrogen fertilisers and iron will tend to acidify the soil, making Woodrush worse. Special management of the weed is often needed to grow it out of the lawn over many years.
Field Woodrush can be controlled through an application of a weed-control as part of a regular treatment package, and I also recommend reducing the acidity through a pH adjustment treatment in the autumn.
If you have a problem with weeds in your lawn, then get in touch. I will be happy to advise.
