Advanced Lawn Maintenance
Some cool season grasses grow in clumps and do not produce runners. Any damage to these lawns will result in bare patches, and the grass will not grow back into these areas.
Generally there may be dieback in lawns as a result of any disease, drought or other stresses that the turf may suffer. The lawn may also become thin and less attractive, and may be more susceptible to weed invasion.
Renovation period is great time to over sow and thicken up the lawn and ﬁll in any bare patches that have developed during the year.
Contact your turf renovation specialists or Area Manager for the correct use and seeding rate, and how to sow the seeds evenly and easily for your lawn.
One of the main beneﬁts in topdressing is to correct the variations in surface levels that occur over time.
When considering top-dressing its important to select the correct material. Generally a mix of sandy loam or triple washed river sand, or a mixture of the both, is used as top dressing material.
The best way to spread the top dressing material evenly across the lawn surface is to use a lawn leveller, or a similar tool to rub the top dressing into the lawn surface.

Bare patches in your lawn may occur for a variety of reasons, for example heavy trafﬁc and excessive shading.
To regenerate bare patches, a light cultivation to reduce compaction and eliminate weeds before you start is recommended. If your lawn type can be established from seed then you may be able to reseed the bare patches.
If you have Couch, Kikuyu or Buffalo lawn you may take runners from the healthy lawn areas and plant them in the bare patches. If the bare patch is large and you need an instant cover then you will be required to order new turf and have it laid accordingly. Contact your turf renovation specialist to ﬁnd out more with regards to your lawn speciﬁcally.
Coring is one of the best ways to relieve the inevitable soil compaction that occurs with normal trafﬁc wear and tear around the home.
A coring machine has special hollow tyens, which are driven into the soil under the weight of the machine and removes “cores”, about the size of an adult’s index ﬁnger. The coring machines action has a shattering effect on the soil and this helps to relieve compaction whilst the removal of the cores, allows air and water to penetrate deeper into the root zone, thus improving condition for growth. Rake up the cores and remove them from the lawn.
To improve soil quality top dress the open core holes by ﬁlling with triple washed river sand or a similar grade of material, or other amendments such as lime, gypsum and fertilisers, as recommended by your lawn renovation specialists.
Thatch is a layer of decomposing organic matter that builds up on the soil surface, underneath the leaf cover. Thatch accumulates when the build up of organic matter occurs faster than it can be naturally broken down in the soil. Excessive build-up makes it more difﬁcult to mow without scalping. It also limits water penetration to the soil and makes the lawn more susceptible to heat stress.
Thatch can also harbour insects and disease and can prevent lime, fertilisers and other products from reaching the soils beneath.
A dethatching / scalping machine removes the layer of thatch.
Consult with your turf renovation specialists with best practice, and best time of year for this to be completed for your lawn.
