My main dilemma is trying to eradicate Butterbur , Sumach ( and Celandine) from my planting areas...........I have been working on the principle of lifting shrubs which I wish to retain and digging out or weedkilling the offenders.
However, there does come a point where some stuff has to be replanted into what "should" have been a cleared area. I did this with a Peony earlier this year..........Peony flowered beautifully and thrived BUT unfortunately so did the Butterbur which is now growing thru the Peony.
As both my Peony and I are getting a bit fed up with the constant moving, I did wonder about spraying the butterbur whilst in situ...........it will be difficult to separate the leaves but could be done at a push.
Knowing that Glyphosate travels down the roots to kill the offender, does anyone know as the roots of my Peony are thoroughly entwined by the Butterbur roots, if the glyphosate would affect the Peony too ?
I ask because I have been doing the same thing with Sumach suckers and a nearby Choisya, whilst not the best specimen in the world, looks even worse than it did last year.
Any ideas or advice/info would be very welcome.....thanks...
