i recently had a minor problem with weeds in a flowerbed of mine. the weeds were a mix of things but the worse was purple nutsedge. so to fix the problem i had to buy image herbicide to kill most of them. on the label it says do not use where roses (and others)will be planted within a year or so. i had intended to put 4 to 6 rose bushes here next spring. does anybody have experience with image or some other herbicide thats supposed to be bad for roses? do you think 6 months or less will be enough to allow me to plant my first rose? if not, is there anything else i might be able to do?
