You know there is a dry granular fertilizer called "blood meal" that's supposedly great for roses. A neighbor told me broadcasting it around the garden was a way to keep the cottontails out, so I used to do that. Of course you have to replenish it after each rain. I don't know about roses, but it sure did make the bermuda grass grow good around the garden.:laughing:
And I never bothered composting, but did like to throw the egg shells and coffee grounds into the garden and till them in.
