pachysandra infected with gout weed
I have a bed of nice pachysandra which has been infected with gout weed. I have tried weed killer but it also kills the better plant. Is there any way to kill this without weed killer? Could the pH solve the problem, as I understand pachysandra likes acid soil. I don't know about gout weed. Thank you.
Really the only way to control goutweed (aka: bishop's weed) is to hand pull it and mulch around the area where it keep popping up. You could try using Roundup, or even boiling water, and spot treat the goutweed while covering your pachysandra with a shield of some kind (like cardboard). Still the best way would be to simply pull or dig it up.
