Banana Peel Tea：Steep chopped banana peels in water for 24-48 hours. Use the strained liquid to water the base of the shrub in early spring to support prolific blooming. Discard peels in compost.Pruning
- Prune immediately after flowering, as it blooms on old wood;
- Thin out up to one-third of the oldest stems to the ground annually to rejuvenate the shrub;
