I have a fairly large yard. Here's a photo of the yard as it was right after mowing it a long time ago:
Last year I hired a couple of guys to use a bobcat and scrape off the weeds and top layer of soil so I was left with nothing but dirt. Since then, I haven't had to touch it. Of course, the year's gone through its course of seasons and now the weeds are all back.
The bobcat job was a fluke. I got a super low price for the job that I'll never get again. However, I still want to be able to NOT deal with any weeds for at least a year. I'm getting ready to cut them all down again, and the plan is to apply RoundUp. I've experimented with the roundup in other parts of my yard and so far everything I've applied it to is dead and dry to the point where I can scrape my foot across it and there's nothing but dirt left behind. That's what I want to do to the entire area you see in the photo.
Since I've never done this before, I'm not sure what to expect in terms of the lasting effects of the Roundup. It advertises as keeping weeds away for 4 months, but I'm sure there are many factors that go into it.
I'd like to be able to cut the weeds down now, apply roundup, and not have to deal with any more weeds until they inevitably start growing back next spring. If I apply the Roundup now, in May, would it keep the ground bare at least through the winter? We have really hot summers, although the crazy rainy day shows up once in a while. I'm assuming a few days of rain here and there won't bring back the weeds, correct?
I realize my post is long-winded. I apologize.
As a side question, I've been using the single-gallon tank sprayer to apply the roundup to smaller areas. When I bought the sprayer, I saw a device you attach to a hose that I can put the roundup in. It has a dial that lets me set the chemical/water ratio and looks like it would make covering such a large area easier, but would it actually work? I don't want to end up wasting the Roundup because too much water was mixed in.
I'm also on a tight budget, which is why it would be nice to only have to buy the roundup once a year (I think I would have to get the $100 ultra concentrate bottle).
