Sometimes our lawn can be invaded – not just by weeds or pests – but by other lawn varieties. It can be frustrating and not very nice to look at – especially if you have invested time and money into having a specific lawn variety installed.
Lawns being invaded can happen in a variety of ways:
- A previous lawn – if a previously laid lawn is not disposed of correctly before a new lawn is installed, the runners or seeds can emerge and the invasion of the new variety of lawn begins.
- Lawn seeds – other lawn variety seeds can be brought into your lawn by the wind, bird waste, on clothing or even on the fur of animals.
- A neighbouring lawn – quite simply a neighbour’s lawn can creep through the fence and invade your lawn.
There’s a few ways you can go about stopping the invasion, depending on how bad the situation is. If the invasion is still relatively minor then you can simply pull out the invading grass by hand – this is the most effective and easiest way to remove it.
If the issue is bigger – If your lawn is Couch and it’s being invaded by Buffalo then selective herbicides and ‘weed and feed’ treatments can very well kill the Buffalo and any weeds too.
If your lawn is Buffalo and being invaded than selectively painting the invading lawn with Glyphosate poison may be the best option. Stop all mowing and lawn care to allow the difference in the lawn varieties to become extremely obvious. Prepare the Glyphosate mixture in an open container that won’t spill easily and set in on top of newspaper on the lawn to stop any accidental damage. Wear rubber gloves, separate the unwanted lawn by hand and use a 30mm wide paintbrush to paint the long leaves of the invader.
You should see results in 1-2 weeks but continue to check for any of the invading lawn that is still healthy and might have been missed. You can start mowing again in about 2 weeks as the poison will have worked its way through the invading lawn, but still dispose of the lawn clippings in the rubbish bin for the first 2-3 mowing sessions. Don’t put them in the green bin, compost heap or garden bed.
Once you have the major issue under control, you can continue with mowing and lawn care as normal. Any signs of new invasions can be handled by pulling out by hand or using a small amount of Glyphosate mixture.
