The most common cause of a dying lawn is lack of water.  If your lawn is showing signs of dehydration this is an act now situation.  Fortunately, it is the leaf of the grass dying and not the whole plant. Applying enough water to wet the top 100mm of soil and keeping this soil wet with frequent waterings will rehydrate the grass and it will recover. 

Compaction, excessive thatch and hydrophobic soil can also prevent sufficient water reaching the roots of your lawnRefer to the Useful Information section of our website to learn how to resolve these issues.
