One the biggest secrets I am often asked to share is what I do to get my beautiful roses. I don't use rose food or fertilizer; I use banana peels. I just scratch the mulch and dirt back from the rose plants and tuck in one or two banana peels, then replace the soil and mulch. Lucky for me, my husband eats a banana every day. I have a lot of roses, so I collect the peels during the winter and freeze them in a glass jar.
