How to remove tree roots?

We bought a property which had artificial grass carpet in the backyard. To our shock, we just discovered tree roots growing all over under the artificial grass. They are from the trees just outside the fence. Fortunately trees were pulled off by the council a month ago. We need assistance with removing and killing tree roots and cleaning the backyard soil for landscaping. Please share your thoughts on what and how shall we fix this issue. Thanks.

Re: Tree roots and landscape

Hello @PR 

 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about landscaping your backyard.

 

That surprise discovery of tree roots under your artificial grass can be a bit daunting, but now that the trees have been removed, you’re in a good position to start fresh. Begin by pulling back the artificial turf and removing any leftover weed matting or debris. Use a garden fork, mattock, or something like the Cyclone trenching shovel from Bunnings to dig out as many visible roots as possible. If there are thicker, stubborn roots, you can cut them and treat the ends with a product like Yates Tree & Blackberry Weed Killer to help prevent regrowth. Always follow the safety instructions and avoid applying it near any plants you plan to keep.

 

Once the roots are dealt with, focus on preparing the soil for new turf. Since it’s been covered for a long time, the soil will likely be compacted and lacking nutrients. Break up the top 10–15cm of soil with a garden fork or a rotary cultivator. This will help with drainage and allow new turf roots to take hold. Mix in Scotts Lawn Builder 8kg Plus Organics Lawn Food & Soil Improver to boost soil health. If the soil feels heavy or sticky, adding gypsum can help improve structure and reduce compaction.

 

Once the area is levelled and soil amendments are mixed through, lightly water and let it settle for a few days. Before laying turf, apply a starter fertiliser like Hortico 8kg New Lawns Starter Fertiliser. Water the area the day before so the soil is moist but not soggy—this helps new turf root in quickly. Taking the time to prepare now will make a huge difference to how well your new lawn establishes. 

 

However, if you have other plans in mind, please don't hesitate to tell us or ask more questions in regards to your backyard garden project.

 

If you need further assistance, please let us know.

Re: Tree roots and landscape

Could I please ask once we use/spray poison to kill the roots, is it okay to cover the soil  same day with natural grass turf.or it MUST be kept open for a day or more before covering again with grass turf? Thank you.

Re: Tree roots and landscape

Hello @PR 

 

It is difficult to tell how far and how deep the roots have travelled. I suggest tracking the roots back to its main branch where it started to spread out if possible and cutting them off from there. Digging down to 200mm to remove the roots in that location should be enough to clear the area for lawns.

 

Let me call on our experienced members @Noelle and @homeinmelbourne for their recommendations.

 

If you need further assistance, please let us know.

Re: Tree roots and landscape

Hi @PR 

In my opinion,. it would be best to leave the sprayed/painted roots exposed to the air for a few days to allow the product to be fully absorbed into the roots before covering them over with soil and/or turf. It may take up to three weeks for the poison to break down in the soil, so be aware of that time frame when contemplating soil preparation and turf installation.
