With only a few weeks till the start of Spring, its a perfect time to start preparing your lawn for the growing season and one of the best ways you can do this is by coring.
There are so many advantages for your lawn and now is the time to do it while your soil is soft enough.
I’m fairly sure that most people who own a lawn have some idea what lawn coring is and while it’s been around for ages as a process to maintain your lawn, in our experience, it’s something most people don’t do which is interesting because there are a lot of compelling reasons to consider it.
Lawn coring is where small cores are removed from the lawn which are typically 10mm wide and 50mm long. A core is generally removed about every 150mm across the surface of the lawn. As you can imagine, 1000’s of these cores are removed which need to be raked up and put in the bin.
You may be surprised to know that lawn coring is a hugely beneficial thing to do for your lawn. There are many advantages including the following:
- Coring introduces oxygen back into the soil which is essential for lawn health.
- Coring removes a significant amount of root thatch from the lawn which together with the extra oxygen and free soil space, allows the lawn to reach down further into the soil profile leading to a healthier, more resilient and even more drought tolerant lawn.
- Coring improves water flow through the soil profile which does a couple of things. It can alleviate waterlogging and it can also lead to a deeper root zone because more water and nutrient are available deeper in the soil.
- Coring alleviates compacted soils.
Coring can be undertaken fix a problem such as waterlogged or compacted soils but it can also be done as a matter of maintenance, on a yearly basis to improve overall lawn health and to reduce water and nutrient requirements during the warm months.
While you can core at any time during the year, August and September are two of the best months. The increasing daytime temperatures will mean your lawn will be showing signs of coming out of winter dormancy and the winter rains will mean the soil will still be quite soft, allowing the core tines to go deeper into the soil.
Coring is not a complicated process but I would recommend using a coring machine rather than trying to do it with a hand style corer. Coring machines can be hired from most hire shops if you want to tackle the project yourself, or you may want to employ the services of a contractor to do it for you. Contractors generally use a much heavier machine than the type you would hire and because of that, the coring tines go much deeper and therefore do a better job.
Would I recommend coring as a form of preventative maintenance? – absolutely. It will definitely pay dividends in keeping your lawn in tip top shape.
Lawn coringBy: Renato on 4 September 2019Hi. I live on a sloping site with staircase leading to my lawn. I'd imagine that would preclude capacity for mechanical corer to undertake this work? I've only got 50sqm of sapphire buffalo so wonder if it's worthwhile given the lawn is only coming up to two years' old. What is your advice.

Hi Renazo Thanks for your questions Even though your lawn is only two years old we would definitely recommend coring it. Coring will help to improve drainage and provide more oxygen to your lawn, thus improving its overall health. Now is a good time as the soil is soft. As for the coring machine contact either the hire shops or a local contractor to see if one would be able to access your lawn area. Thanks again for your questions Renazo
Lawn CoringBy: Heather Woolley on 16 November 2018I feel our front lawn needs coring /aeration very badly, it has brown patches and lots of runners on top . It is Buffalo, i have tried every thing to bring to how it was, although much better needs something more. I live in CarolineSprings
