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 for your lawn.
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, September is one 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.
So would I recommend coring as a form of preventative maintenance? – absolutely. It will definitely pay dividends in keeping your lawn in tip top shape.
