We have trees that keep growing back after we dig them out?

Question

another grows in another spot. The roots are long and tough to remove. The tree will grow really tall really fast with a soft trunk. Long branches with rows of little leaves, like a fern style. It has a strong smell that stays on your hands.

Help us get rid of these things. How do we kill the roots they just keep spreading.

Answer 1

You either need to dig out the whole rootball as in the case of ground-elder or get a proprietary rootkiller from a hardware shop. Drill several holes into the stump, pour the stuff in and let it do it's thing.

I had 12 to get rid of in my garden and it looked like the Somme afterwards! It looks good now though.

Answer 2

Sounds like "Tree of Heaven".  I planted one cause I thought the seeds were cool, and they are pretty.  But yeah, very fast growing.  Big weed.  

I was lucky and got most of it out the first time. Only had a few more to pull.  

Getting some concentrated Round-Up (generic stuff may be better) and cut the trunks and paint the herbicide on.  

  Garlon I thin is another thnig that kills trees from the inside.  

  Keep at it. You can get it gone.  Maybe take a year.  But stay on top of it.  I feel for ya.

Answer 3

Similar to my syringa tree that is invasive. I manage to kill the 10 metres mother tree by ring-barking and drilling holes around the base and putting hydrochloric pool acid in the holes. The big tree died but new ones sprout because the roots are still alive deep down the soil. I just have to resort

pulling the new growth at least every 3 months. The good thing is at least there's no more big tree to bear fruits and scatter all over the garden and mess the roof gutters..
