We have a row of something like boxwood or similar shrub in between our rented home and the neighbor's. The entire row is just full of asparagus fern which we'd like to get rid of........ without killing the shrubs. This row of shrubs may have been planted 25+ years ago, and is very dense, so getting these ferns out by the roots is a non-starter (I've had enough trouble with it all on its own, so I know better than to try).
Any ideas??? Pleeease!!!!
