This being the first year here I really didn't prepare properly last fall when I cleared my garden area. There was a lot of thistle in that space and I had hoped that with a lot of weeding, etc. that I could stay on top of it in my veggie garden, and eventually be rid of it. But, I guess it's not meant to be during the growing season because it's getting the better of me. This stuff is horrible and it's next to impossible to stay ahead of. I know there has to be a way to get rid of it for good and I'm hoping that you all can help. I'm thinking that in the fall, when I put the garden to rest for the season, that if I till everything under, spray (or drown) the whole garden area with round up, mulch, then cover with black plastic for the winter that it might kill off the thistle seed. Or should I spray, then till & mulch? Is that realistic or is there some other way to get rid of this stuff. I can't plant, due to rain and late freeze, until mid or late May. So if I keep it covered as long as possible would that kill the seeds so this stuff doesn't come back next year? Please, I need advice from all of you seasoned gardners out there.
