Five Common Lawn Weeds – Identification and Treatment

It is always easier to control weeds from the outset rather than try to remove them once they get out of hand. By choosing a suitable lawn species for your area, keeping it healthy, well maintained and at the right mowing height for your chosen variety, you’ll have a leg up on the neighbours.

Identify and remove weeds early – dig them out by hand when they are young, small and easy to remove. Once they get larger it becomes harder and if they set seed they can spread all over your lawn and garden – bad news.

Many small weeds many be carefully pulled out by hand, however you will need to make sure you have removed the roots. Using a weeding trowel or long handled, mechanical device and prizing around the roots will help ensure total removal. The bigger the weed, the bigger and stronger the roots. In some cases, a weed spray might be necessary.
