All suburbs have different soils so look for a fertiliser blend for your area.
Maintaining a healthy lawn
To keep your lawn in great condition it will require year round maintenance including watering, mowing, fertilising, top dressing, de-thatching and regularly applying a quality wetting agent and/or moisture retainer.
Many West Australian soils do not absorb water well. In fact they often become ‘hydrophobic’ meaning that they actually repel water. In grey sand areas, in addition to applying a soil wetting agent, such as Aquaforce, and the MRA Moisture Retaining Aid BIAGRA during the laying process, we highly recommend regular application at least three times a year of these or similar products; at the beginning of Spring, the beginning of Summer and again mid to late Summer, (with application rates as recommended by the manufacturer or your local TGAWA member turf grower)
Once your lawn is established you can only water once on your rostered watering day, being twice a week for potable or scheme water users and three times a week for bore users, (either before 9am or after 6pm). It is generally best to water early in the morning as it allows the water to soak to the roots and be available throughout the day when it needs it most. With current watering allowances it is imperative that quality wetting agents and MRA’s are used to assist with keeping water supplied to the root zone of your turf
By fertilising your lawn you are providing it with a range of nutrients for good health and growth. Apply a slow release fertiliser every two months during the warmer months and once during winter. It is important to note that when fertilising the recommended application rate is the maximum amount that should be applied. Always apply fertiliser to a dry lawn and water in well, as fertiliser applied to a wet lawn and not sufficiently washed in can result in leaf burn.
Remember that if you apply fertiliser excessively, whatever your lawn doesn’t use washes into and affects the health of our waterways.
Mowing your lawn will help to keep it healthy and looking good. During summer your lawn will require more frequent mows (ensuring the blades are sharp) every 7-21 days to the height 10 to 20 mm depending on the variety. (Please refer to recommended heights in the WA Turf Brochure below.)
