When in drought
Before you do it’s wise to spike the lawn first to relieve compaction and allow water to penetrate to the roots. A spiker attachment on the garden tractor or purpose built spiker/aerator will do the job of helping prevent the water sitting on the surface.
When asked how long should you let the sprinkler run for, a handy tip is to leave a clean, open jam jar on the lawn with the sprinkler running. When the jar has collected 13mm (0.5”) of water the sprinkler has been running long enough on an established lawn.
Newly laid lawns or those raised from seed in the spring will need more watering during their first summer. You’ll be mowing regularly if there is rainfall, though not during drought but it will help the grass in hot weather if you raise the height of the cutter deck a little to help prevent the lawn drying out.
Mulching is another aid and if you don’t have a mulching deck you can leave the grass collector off to do a similar job of letting the cuttings help protect the lawn. A light application of fertiliser on an established lawn is beneficial this month. If it’s dry and you can’t water use a liquid feed rather than a granular one. A weed and feed treatment earlier in the year will have put paid to most of the typical lawn weeds but if you have any persistent ones they can be spot treated.
