Micky's recent post asking about Roundup inspired this.
Years ago, we planted some Boston ferns around an oak tree. Their purpose
was to fill in densely and prevent 1000s of baby oaks from popping up from
the roots. The ferns did that admirably; however, they tend to extend their
domain into areas where we don't want them. I always controlled that with
They are at it again so eight or so weeks ago they were sprayed. No result.
Two weeks later they were sprayed again. No result. Two weeks later they
were sprayed yet again but with a double strength mix. No result.
I know the Roundup is good, other plants in other areas were sprayed, dead
as door nails now. Any idea how/why it isn't affecting the ferns?
