Bleeding hearts is over running portions of my garden. When I try to
dig up the roots i always end of splicing the roots. And wow do the
roots of that plant spread out....

Considering I have lots of ground cover that I'm trying to preserve if I
dig up Bleeding hearts' rootball but end up leaving a portion of it in
the ground, whats the likihood of it growing back? The trowels just
slice thru the roots.

Other than digging up the root of the plant, is there another way to get
rid of selective bleeding hearts without damaging the other
plants/ground cover? Something with a syringe?

Looking for all manner of advice
