Thatch can be the result from poor soil, irregular mowing and neglectful maintenance.
Excessive chemical use (particularly herbicides and pesticides) can kill beneficial insects and microbes that usually live in your soil and help eat the thatch.
Good news is removing it doesn’t need to be complicated. It is likely that you even have the equipment on hand.
If your real keen, you can investigate hiring a lawn dethatching machine.
Dethatching will leave your lawn a hot mess for a few weeks, but it will recover if done properly. It is best to dethatch your Townsville lawn in August, any later and it can be too hot.
Dethatching your lawn at the wrong time of year will result in slow recovery and provide bare areas for weeds to grow in. If you, do it when its too hot (particularly from November to February) you can burn the stolons or runners and kill the lawn completely. If you, do it when it is too cold, it just won’t grow at all because the grass is dormant.
Do not scalp your lawn too early (its first growing season) as it needs time to develop a strong root system.
The intermittent use of an organic fertiliser, like Dynamic Lifter can help reduce thatch because it will improve your soil condition and stimulates the growth and activity of beneficial microbes.
Test your soil pH level and correct if needed. A healthy lawn full of rich organic matter will have less thatch.
Grass clipping can be very beneficial for the lawn when you have a healthy soil as they decompose quickly and provide nutrients and organic matter, however, clippings can add to a thatch problem once it exists. It is best to collect grass clippings in the warmer months when they are dense and more likely to sit in piles on the lawn killing the grass underneath. In the cooler months, can be the perfect time to leave them on as there are less.
