(Cue everyone showing up in my mentions to tell me how bad glyphosate/roundup is… now).
Oh, yeah, roundup is pretty nasty stuff that shouldn't be sprayed near any plant. It's TERRIBLE for them. and would you do that to a sweet innocent little blackberry bramble (just to mention a random plant that may have been infesting my yard until an series of awkward encounters with glyphosate last year.)
