Spanish invasion.

Spanish bluebells have taken over my garden. I still have a tiny clump of native bluebells but they are not yet in flower. Elsewhere these thugs have taken over. I tried last year to dig up quantities of them, but they are quite deep, and I obviously failed in my mission. I am no longer in control of my spring garden with these bluebells everywhere and no sign of my beautiful tulips because the squirrels have feasted on them. I wish squirrels dug up bluebells!
