I'm a novice gardener, recently moved into. an old house and have a lot of montbretia around; this is a fraction of the area it’s growing in.

my question is, how am I meant to get rid of the corms without dumping all this soil? They go so deep, and it’s impossible to separate the corms from the earth and Even if there was somewhere to dump it, would be too heavy to move all of it.

Not sure what to do other than let the montbretia win.
