If you’re in any drought.
Frequent mowing of the lawn and removing a little more often is beneficial for the grass. Mowing once a week is likely now. Don’t be tempted to cut very short, especially in the dry periods. In fact, many people will prefer to mulch in extended dry or drought conditions.
Using a mulching deck on the garden tractor the blades chop and chop again until the grass is in particles which return to the lawn and help it to retain moisture, while acting as a fertiliser. On that note, if your lawn is moss and weed-free you can apply a high nitrogen summer lawn fertiliser. On the other hand, if you have a weed and moss problem it’s not too late to apply a combined fertiliser, weed and moss killer.
