Peace Lily Removal?

richard49richard49 Posts: 22
I have a small border where there were Peace Lily plants; I removed the plants (as best I could) to use the area for other planting.

Ever since the Peace Lily plants have been re-growing due to the small 'bits' left behind, or small parts of the roots I missed.

I've been trying for the last year to stop them from growing so this morning dug up the area they were in to see if I could finally get rid of them but found a huge amount of them coming up under the soil.

It feels like I'll never get rid of them!

Have you got any suggestions apart form digging out all the soil to quite a depthe and replacing it with fresh soil?

Thanks.

    Where are you? The only Peace lilies we have here are houseplants :)

    I wonder whether what you've been removing is wild arum, @richard49?  Peace lily is an indoor plant, though its leaves look a bit similar to wild arum.  

    I have a lot of wild arum in my garden.  Digging out as much as possible, very carefully following the leaves down to remove the little corm from which they grow, seems to be the only method which works - but only up to a point, as you've found.  Not only do little bits of corm re-grow, but the plants seed themselves readily as well.  I dig them up when a clump is in the way, and otherwise just pull up the leaves when I see them, which weakens the plant.

    I don't have a great knowledge og plants and as they looked like Peace Lily's That's what I went with; but yes, they are probably wild arum.

    I tried using a hoe to slice through them as soon as they appeared hoping that would weaken them to the point of dying off but no luck there.

    If you can pull out as much of the top growth as possible - including the white underground stem - that should discourage them for most of the growing season.  You can kill any weed, even dandelions and couch grass, if you remove the green top growth as soon as you see it, though it may take a while.  My grandpa used to say "Hoe every Tuesday..."  -nothing special about Tuesdays, it was just the frequency of hoeing which was important.   :)
