I hope this isnÃ¢â‚¬â„¢t a controversial subject , but IÃ¢â‚¬â„¢m after some help to get rid of my triffid like mint. I was foolish enough to plant it in a trough next to a strawberry plant and it very quickly took over! I pulled it all up and replanted in a pot (much safer!) and then dug up all around the existing strawberry and got rid of all the runners I could find.
I thought IÃ¢â‚¬â„¢d managed to get rid of it and subsequently planted 2 more strawberries but itÃ¢â‚¬â„¢s started coming up again. I dug up more runners and have covered the surface with a thick black bin liner with the strawberries poking through it, but the mint is still coming up under the plastic. Ever few days I look underneath and there are more shoots! ItÃ¢â‚¬â„¢s even started coming up through one of my strawberries!
How can I get rid of it?! Is there any safe way of applying a weed killer to the mint without affecting the other plants?
