Lawn Maintenance For Dry Climates

Spring is the ideal season for bringing back to life a lawn in a home garden that has seen better days. An understanding of the causes on the other hand, improves the chances of successfully revamping the lawn, and ensuring that the same pattern does not repeat itself in the future. Sometimes the seasonal change can be blurred but you can find the best Turfing services in Brisbane to get an all year low maintenance yard.
The reasons why a grass degenerates can be boiled down to two main factors. Other tasks such as feeding and de-thatching, contribute to the success or otherwise of the lawn.

If a lawn has been poor from day one, then it’s reasonable to assume that the soil was not adequately prepared prior to turfing. Assuming however that a grass did grow satisfactorily at one time, but has since declined, and assuming as well that the routine maintenance tasks are in order, then the reason behind its decline can probably be traced to compaction at the topsoil level, caused by the impact of excessive foot traffic on a relatively small area.

In many cases, topsoil compaction can be relieved by the actions of a scarifying or de-thatching machine, that not only removes the thatch (the build-up of organic matter that decomposes very slowly) but also digs into the soil to a depth of one or two cm, thereby breaking-up the hardened, impervious top layer of the soil.

Scarifying is most effective on perennial grass varieties such as Bermuda, Zoysia or Paspalum that grow by means of rhizomes. Conversely, great care must be taken with grasses that have shallower root systems and spread by stolons.

Shortly after the de-thatching/scarifying, the lawn should be fed with a balanced fertilizer, containing the three macro-elements; phosphorous, nitrogen and potassium. For environmental reasons, readily soluble fertilizers such as Ammonium Sulfate are not recommended today, but excellent results can be obtained from controlled or slow release fertilisers.
