Anyone got any tips as to how to remove all the "spawn" of growth arising
from taking out an acanthus ? |

Removing acanthus
I had two clumps of Acanthus in different parts of my garden that I wished
to remove. I tried digging it up, as you did, but the roots are long and any piece left in the earth will send up more shoots. So I tried a different method for each of the clumps and they've both worked - I'm acanthus-free this year! I laid thick black plastic sheeting (I used an old compost bag, spread out with the black interior face down) over the growing shoots from one of the clumps, securing the sides down with bricks to shut out all light - and left it in place for a couple of years. I put some pots of flowers on top to disguise the plastic. The shoots from the other clump I sprayed with Round-Up - they do die down but will send up more, which you need to spray again until the root system is killed off. The time to do this is when the leaf is growing, from late spring onwards. It's not too late now but you may have to repeat from spring next year, and that should do it. I don't know why the experts on the gardening programmes enthuse so much over Acanthus - it's spiny, and invasive, and not easy to get rid of. Mind you, I can appreciate it for its structure - but only in the large garden of some stately home! NB. Before spraying the leaves with Round-Up, you must cover adjacent plants (I put plastic shopping bags over them) as it's a systemic herbicide and you might otherwise lose them. Obviously, take the bags off afterwards once the spray has dried on the leaves (you need only a fine spray - don't over-wet the leaves). Avoid a windy day as you will get spray drift, and spray when there is unlikely to be rain for several days. PS. I found Round-Up also successful at killing off Ground Elder, though it took several seasons. I had loads of it in my garden and now I have none. "p.k." wrote in message ...

At my last house I had, for topographical reasons, to build a long raised bed with railway sleepers along the lower side of the house. I was skint, so I had to fill the bed with some awful stony subsoil mixed with builder's rubbish. Acanthus loved it: given a start with some better stuff, they grew well and the clumps increased nicely, but gave no sign of invasive suckering. Plenty of seedlings popped up in the path below. -- Mike. |
