I Desperately Want To Dig Up The Spanish Bluebells That Are Invading Our Back Yard.

Question

Unfortunately they surround a cherry tree and a plum tree, both of which were planted after the bluebells, which must have been lurking underground for years. They create a wet and slimy mess after blooming, and they multiply like crazy.

Answer 1

Unfortunately, weed killers don't seem to work on Spanish bluebells that are spread by underground runners connected to bulbs. The best thing to do is dig them up. I know that seems impossible if you have a large infestation.

You might try a weed killer first to see if that helps at all, then go at it by digging when they are actively growing.
