Answer: Banana peels are a source of potassium so you can bury a banana peel in the soil around your roses if you'd like. Feeding Hybrid Tea, Polyantha, and Floribunda roses should begin in the spring and continue throughout the summer growing season. The first feeding should come in early spring as soon as leaf buds begin to swell. Clear away mulch and work plant food into soil around the plant. Use 1 rounded tablespoonful of fertilizer per plant (or 1 pound per 25 square feet of bed area). Second feeding should be made at the same rate and immediately following the first heavy bloom. Third feeding, also at same rate, should be made in late summer. In southern areas, where blooming extends into October and November, a fourth feeding should be made about the first of October.
