I was taught to place a banana (peel and all) in with roses I am planting (new bare root plant) or transplanting/moving to prevent shock. After my rose is well placed in its hole, I add apx 4-6 inches of dirt then drop the banana and finish planting as directed. To encorage deep root growth (I live in zone 5 of Midwest) I place a 1-1.5 inch diameter of pvc pipe- cut to abt 12-14inches in length, in the hole abt 6-8inches above the soil covered root ball. I fill the pvc pipe with gravel and sand. I water primarily through the pvc so water goes deep. I will minmally water at the top to keep soil around base of rose soft. During the summer when our rains are minimal, my roses are loaded with blooms while others in the neighborhood are suffering. Any time I have over ripe bananas- they get dropped on the roses. I loosen dirt around rose to abt 4 inches deep, place banana, and cover it up with the loosened soil. My roses seem to really appreciate 'feeding time' as the bananas really perk them up!
