Lawn coring provides many benefits for home lawns, and this is especially true for many buffalo grass lawns too. And the major benefit for coring buffalo lawns is the reduction in thatch that can be achieved by this process. So lets take a look at all the benefits and the how of coring a buffalo lawn.
Coring A Buffalo Lawn
The lawn coring process involves using a lawn coring machine which punches holes into the turf using hollow tubes called tines. As the coring machine travels across the lawn thousands of holes will be created in the lawn surface, reaching through the thatch layer and into the soil.
The benefits for the lawn from coring are the removal of a small amount of thatch, as well as creating a massive boost of oxygen into the soil area which is vital to good lawn health. This aerating of the soil is the primary purpose of lawn coring and will allow far greater penetration and circulation of air amongst the roots of the turf, and can be very useful as lawns become compacted over years of use.
A further benefit of lawn coring includes the breaking up of clay soils, in which case these air holes should be filled with a coarse sand as a filler which will allow for greater water and air circulation at the same time.
The Lawn Coring Process
The lawn coring machine is quite heavy, and can be difficult to manoeuvre, as well as these things, the operator will need to take great care to avoid any sprinkler systems, as these can be busted from the coring process. A contractor specialising in lawn coring is often the best option for many homeowners as they can do the entire job in one go with no effort required on behalf of the homeowner.
After the lawn is cored it will be covered with thousands of plugs which have been pulled from the turf. these plugs will be made up of lawn, thatch and soil, and should be removed from the buffalo turf after completion. Which is most easily done with a rotary lawn mower with a catcher attached.
An application of quality buffalo lawn fertiliser should be applied to the turf directly after lawn coring and prior to any soils being added to the turf. Wetting agents can also be applied at this time for maximum benefit at the roots of the lawn.
For clay based soils, the holes can be filled with coarse sand, for nutrient poor and sandy soils the holes can be filled with a rich soil mixture. If the lawn soil is in good condition then the holes can be left open and will naturally cover over with new lawn growth within a few weeks.
Buffalo lawn coring should be done during the growing season for the turf and not in winter and not in the heat of summer, so coring during Spring or early Autumn is best.
Added Benefits For Buffalo Grass
Apart from all the normal benefits lawns can get from coring, coring buffalo grass does give us one added and important benefit with buffalo.
And this is the removal of thatch. Lawn coring is a good way of removing some of the excess thatch which is present in buffalo grass lawns. While lawn coring is not the best method of thatch removal for lawns, it is a good alternative for buffalo grass which can be very difficult to dethatch safely.
For maximum benefit of thatch removal from coring buffalo grass, the lawn will need to be cored once every couple of years to achieve the best and most consistent ongoing results.
In saying this, we must say again that lawn coring is only a minor way of removing thatch from buffalo grass, and should form part of an overall thatch management plan for this grass type.
When Does Coring Buffalo Grass Become Useless
Lawn coring will become useless and of no effect once the thatch layer of the buffalo grass reaches to a greater height than the height of the tine of the lawn coring machine.
Once this happens, the coring will never reach into the lawn soil, and will therefore be of no benefit to the buffalo lawn. In fact, once the tine can only reach one or two centimetres into the soil, the process is still almost useless.
For these reasons, we can see the vital importance of coring buffalo grass regularly, as well as using other methods to control buffalo thatch over the life of the lawn.
