Answer: I think hand pulling and then putting up a barrier between your rose bed and your lawn is the best solution but you can use a natural weed killer if you feel the need to spray. The only coup is that you'll end up pulling out the dead grass and roots anyway, so you may just want to forego the use of a weed killer. There is a product on the market called Natural Weed Control. It is a mixture of 20% vinegar and orange oil. It will kill the grass without harming your rose bushes, just as long as you make sure not get any overspray on the petals or the leaves of the roses. You can order the Natural Weed Control product on the web or you can check with your local garden center.
Good luck with your roses!
