Lawn Weed Treatment
Hand removal
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.
Herbicides
There are various herbicides available, including selective and non-selective. Non-selective products kill most plants including your lawn; selective herbicides target specific weeds only. It is strongly recommended that you consult your local nursery or turf expert to properly identify the weed in question first, so you can treat it with an appropriate and effective spray.
You will also need to check the suitability of the selected herbicide product for use on your lawn type. For example, many are not suitable for buffalo lawns.
For the weeds listed above (cudweed, dandelion, clover, bindii, creeping oxalis) you can use Bin-Die or Weed Control, both are safe to use on all turf varieties except ST varieties of buffalo.
Turfco carry a wide range of weed and pest control products for buffalo and other lawn varieties. Remember to always follow manufacturer’s instructions on the pack.
