Lily of the valley is a thug when happy. It ironically takes ages to establish and can be impossible to grow sometimes.
I'm now removing lily of the valley....every piece I see....after a few years trying to grow it.
There is no doubting the love affair some have with lily of the valley and that removing it is somehow disrespectful. However, digging it out is the best way. The roots are easy to see especially if the bed is to be cleared for other planting.
Is the ground wet? Does it drain well? Lavendar does need excellent drainage ESP over winter and plenty of bright sunshine. So if the ground is suitable I would dig in some grit if you intend to plant lavendar there.
