louise said:I have the same problem with the lily bed in my front yard. I'm thinking of seriously just , with a shovel,
taking each clump out of the bed and placing (perhaps on a large tarp) in the shade. Then, the bed can
be tilled up deeply, more easily clear of grass, fertilized, amended. Then move the lilies back into the
nice rich clean bed where it can be much more easily maintained. I have about eleven different ones
and would be sad to lose any of them.

Leftwood said:Yes, the worst thing about tilling is breaking up rhizomes and stolons of grasses and thistle that will produce brand new plants. I suspect that all around the edges of the daylily bed, grass has invaded. Mulching will not cure this, as the already established grass will come up through the mulch. Barring a chemical approach, I suggest that you will need to dig and remove the grass at the edges, and probably need to dig some of the edge daylilies to extricate the grass roots from the plants. Then mulch.
