Hi everyone. Im a keen winemaker and I've found a spot where wild
brambles are growing with abundance [1}. As a winemaker this is a
great delight to me. However in one large part of the area, the
brambles are interspersed with nettle (the soft stingy type where the
tip breaks off and injects its poison). Is it possible to use a
weedkiller to kill these off without afecting the brambles? If so, can
anyone recommend a brand?

[1] I can easily pick enough for about 15 - 20 gallons.

Thanks in advance.
