Thistle plants have invaded my front flower bed that contains mature azaleas. I have thistle plants growing up in the azaleas and they have spread like wildfire in the bed in front of the azaleas. I have pulled them out by hand; I have used a hoe: I have used a vinegar solution; I tried to smother them with landscaping fabric and mulch. Nothing has worked. Hope you have something for me. I certainly appreciate the product, Talstar that I bought from you for our invasion of stink bugs... the product was incredible!
