2.2 Examples of Performance Standards
2.2.6 Weed content
For most situations a few finer, smaller weeds amongst the grass content aren’t going to be an issue.
However, we would not want too many large patches of broad-leaved weeds though, especially as these can cause a player to lose their grip and slip.
Moss would not be desirable in any large amounts because it is easily kicked out leaving a bare surface.
