Fine turf can quickly become overrun by more vigorous 'weed' grasses.
Coarse grasses can invade turf, epecially where the sward suffers from compaction, drought or excessive mowing. In winter they are more common, as the fine grasses stop growing while these coarser, less desirable grasses continue to develop. Some fine grasses, such as fescues and bents, can also be 'burnt' in freezing weather, which checks their growth. |
