Large Plant Growing In Wall

[muchlovex]

Please help. There is a large plant growing in my wall. I keep cutting it down, but it grows back. It appears that the roots are in between the bricks.

Is there any special way that I can kill the roots without taking the bricks out.

I think the plant is a Butterfly Bush.

They are almost impossible to kill. I dug one up a few years back and chucked it in a dark damp corner to take to the tip and the bloody thing took root.

You could wait til it has some leaves on it and then spray the leaves with a systemic weed killer.

Why do you want to kill it muchlovex? It is fantastic for butterflies, they love it and butterflies are becoming rarer and need all the help they can get. Plus it has gorgeous big racemes of flowers.

I want to kill it as it's causing damage to my wall, which in turn will make it unstable.

I'll try a weed killer on it. thanks

If the roots get bigger it could cause damage to the brickwork. Try pouring a bit of petrol (to the roots if possible)

I'd want to kill it too, ladybirder - Buddleia is a pain in the ground, even more so when it roots in your brickwork as one of mine has. You need serious root killer on it.

It sounds like, just the place where Buddleia would choose to grow.

Cut through the stem and apply 'Brushwood killer' Available at garden centers (SBK)

Keep ripping it out not cutting back, it will die off eventually
