Will anything outgrow ground elder???

I like the idea of attacking it with a flame thrower Daisymae. However I think I’d be safer trying the Mexican marigold or geraniums as my sight isn’t good and I have visions of fire engines racing to the rescue.

Apparently ground elder is edible and quite nice tasting. I have not tried it yet though as I can never find any. I’m probably not foraging in the right places.

I have the same problem with neighbours ground elder and find that Crainsbill geraniums have kept it at bay bay.

I didn't know that anything would outgrow ground elder. The only sure way is to dig it out, but that's not without its challenges. I would be inclined to apply a weed killer. One that's targeted and be vigilant for the next few years. My neighbours have a flame thrower for the weeds, I guess that is chemical free. I have actually got a variegated elder it's not so vigorous as the usual kind. The extreme temperatures last summer have all but done for it.

You could try Mexican marigold, my SIL used it to kill ground elder in one of her borders, apparently it releases a chemical that’s toxic to ground elder. I’ve never tried it myself, but it did work.
