A healthy lawn will always combat weeds! It is extremely important to note that, regular maintenance is key to maintaining a weed free lawn. This includes regular mowing, watering and fertilising to promote healthy growth and crowd out any weeds!

Understanding Lawn Weeds

Heres a few common weeds you may have heard of or even have found in your lawn:

How to Get Rid of Weeds Before Laying Turf

It is very important to ensure you remove all weeds or previous grass types prior to installing your brand new lawn! If you do not do so, these weeds and other grass types will make their way through your new lawn.

Step-by-step guide to weed removal prior to laying new turf:

  1. Clear the area of plants, grasses and any other unwanted weed growth. Pay particular attention to Kikuyu and Couch varieties as these are extremely invasive and may require more than one total kill application. Clearing the area is best done by spraying with a total kill, such as Roundup or Zero (Glyphosate). These needs to be complete a minimum of ten to fourteen days prior to laying your new lawn.
  2. Cultivate or Rotary Hoe dead matter into the existing soil base or export/remove the dead matter off site.
  3. Add in a turf underlay product to make sure you have the best base for your new lawn. We recommend 100mm as a good growing medium for a new lawn. Always be sure to double-check your pH levels to ensure it is still within the appropriate range of 5.5 to 7.

Preventing Weed Growth in Lawn

Keep your lawn healthy!

The obvious but not always easy solution to preventing weeds in your lawn is to keep your lawn healthy. A healthy lawn will combat any weeds due to it’s strong, deep and thick root system and dense growth that makes it hard for weeds to grow through.

  • Use a fertiliser such as Lawn Solutions Premium Fertiliser. To find out more about when and how often to fertiliser read out latest blog How Often Should You Fertiliser Your Lawn.
  • Protect with pre-emergents such as Lawn Solutions Oxafert. Pre-emergents are the best tool for preventing weeds emerging in your lawn. They will stop weed seedling from germinating in the soil.
  • Be vigilant and treat weeds as soon as they appear in your lawn. One year’s seeds is seven year’s weeds! Pull any weeds that pop up in your lawn before they have a chance to go to seed. Once gone to seed, this is when they become particularly stubborn to eradicate.
  • Mow regularly, some weeds can be suppressed with regular mowing.
  • Keep your lawn healthy with a regular watering routine. For an established lawn, our recommendation is to water deeply once per week. Preferably in the morning, otherwise in the afternoons when the temperatures are ideal.

Chemical Weed Control Options

Selective herbicides are able to selectively treat broadleaf weeds or grassy weeds, depending on the chemical without harming your lawn, however non-selective herbicides like glyphosate will kill any plant they come into contact with.

Always make sure to identify what weed you have and what your grass type is to ensure you don’t accidentally kill your lawn! If you are unsure, please email photos through to us at info@allturfsolutions.com.au where we are able to help identify and recommend what product you can use to treat.

Be sure to always follow labelled rates and ensure you wear the appropriate safety wear as recommended on the products labels. Safety comes first!
