How to stop a tree stump regrowing?

Step 1

1/5

Ensure safety and check local regulations.

 

Before you begin, ensure you are protected. Handling chemicals like weed killers can be dangerous, so it’s important to protect your skin and eyes. Always wear gloves, safety glasses, face mask and a long-sleeved shirt to prevent injury. Additionally, be cautious when using power tools like a chainsaw and wear hearing protection and a face shield.

 

It’s also essential to check with your local council before removing any tree from your property. Some areas may have regulations or require permits for tree removal, particularly if the tree is large, protected, or in a conservation zone. For large trees, it’s also wise to consult with a professional arborist. They can help assess the tree's condition and recommend the safest and most effective removal method.

Prepare the herbicide solution.

 

To effectively kill the tree stump, you will need a powerful weed killer. Mix Yates 1L 490g/L Zero Weed Killer Super Concentrate at a ratio of 103mL per litre of water or 51.5mL per 500mL of water. For woodier, more established trees, use Yates 250ml Tree and Blackberry Weed Killer Concentrate instead.

 

It’s important to have this solution ready before you cut the tree down, as it should be applied within 30 seconds of making the cut. Some trees are capable of sealing their cut surface quickly, so timing is important for the poison to penetrate properly.

Cut the tree down.

 

Using a pruning saw or chainsaw, cut the tree as close to the ground as possible - ideally no more than 15 cm above the soil. The closer you can get to the ground, the more effective the poison will be, as it will have direct access to the stump and roots. Make sure to cut in a controlled manner to avoid injury or damage to your surroundings.

Apply the herbicide solution.

 

Immediately after cutting the tree down, take your prepared herbicide solution and carefully paint it over the top of the stump. Be sure to apply the solution within 30 seconds of making the cut to maximise its effectiveness.

 

Focus on the green cambium layer around the outer perimeter of the stump. This layer is vital for the tree’s vascular system and coating it thoroughly will ensure the herbicide is drawn through the system and kills the tree.

Monitor and repeat if necessary.

 

After applying the herbicide, monitor the stump over the next few weeks. If you notice any new growth or suckers emerging from the roots, repeat the process of applying the poison solution to these new shoots.

 

Persistence is key, as some tree species may require multiple treatments to fully die off. Keep an eye on the stump until you’re sure all growth has ceased.

Nice set of instructions :smile:

 

Tho do you have any idea of how to "kill off" a stump without the poison? I have a Jacarander that had to go as it was playing with my overhead power lines. I pruned it back a few times but its also breaking my concrete retaining wall. 

It has grown back into a very nice shrub atm that I keep in check via pruning (its a mass of fine leaves) But I was asking for anyone else that maynot want to use poision.

@Dave-1 Hey Dave, fair enough if you don’t want to use a chemical. Really the best thing you can do is get it removed professionally. Using a stump grinder . Covering the whole stump with a heavy tarp or black plastic with bricks to hold it down will help as it cuts off sunlight and smothers it.

Yeah that was one option, I actually had cut a bunch of roots off it, hacked at it tried to dig under it but it has a tap root I think. And still it came back bushy as! :smile: I think it can stay there and when I remove teh tomatoes I will have another go :smile: I have heard of bicarb being used to help poisin the trees but I really dont think id try it as I grow vegetables in the garden bed. Hands on to remove 😕 

 

Thank you
