I used banana peel to fertilize. I heard this from my son-in-law who is a Master Gardener, then read it on Hometalk. As my roses had been looking sad the past couple of years I was ready to try anything. See 1 mo. results.

Awsome tip! I recently got a job taking care of the parking lots and plants for my town. There
are only 2 of us that take care of every thing. I already use these tips in my own garden and I plan on using them in my work as well. We both are taking the master gardner program this winter and cant wait! Bring on the tips!
