I'm planning to remove several large patches of grass in our front yard and do a lot of tree/shrub planting in those areas this September. Trying to decide the best way to do this. I've done a bit of reading and have found that the following options should work:
1. Spraying the areas with Roundup or Bonide Kleenup.
2. Smothering the grass with plastic or some other sort of material.
I would prefer to avoid spraying anything like Roundup or Kleenup if I can avoid it, so was leaning towards option 2. And I realize that using this method could take a few months to finish the job, so now would be the perfect time to get going with that if I plan to do my plantings in mid September... I was thinking that I could just put large tarps out over the areas I want to remove, and hold them in place with rocks... Or... Maybe I could cover the grass with something else (not sure what) and then mulch over it and leave it like that for a few months. Would something like cardboard work well for this? I guess it would need to be biodegradable so that I could just plant through it without having to pull plastic out from under the mulch... I should add that the grass is mostly rye grass (and lots of clover, creeping charlie and various weeds too!)...
Any advice or suggestions would be greatly appreciated.
