Please help me to kill this weed......

Don't mix mogeton to strong it turns everything orange!

 

Ah, must be what happened to this poor girl. No wonder she looks so surprised.

Try strong vinegar or acetic acid. You could also use Roundup with detergent and/or wallpaper paste, to make the weedkiller stick to the waxy surface of the liverwort.

 

Acetic acid yes. Glyphosate no. Treat early before the formation of sporocarps because it is much more difficult to control after. Or just live with it as said. If you can reduce the moisture in the area and get it dried out and air there will be much less forming anyway

Have you tried bleach on it, did some moss once and it was good:thumbup:

Pressure washer removing all organic material, then repoint if necessary. You could apply Algon by watering can as well. Weedkillers are not going to solve your problem IME.

It's called marchantia. Found this on internet that says to mix a bit of glysophate with detergent to get through the waxy surface.

Thanks everyone for the advice.

 

I probably would have left it but it is coming up between the flags next to the house so is looking a right mess.

 

I agree, I think the key is getting through the waxy surface. What detergent could you use for that? Can you just add washing up liquid to a weed killer or is there a specific product?
