Fertilization
Apply a balanced organic fertilizer as new growth emerges.. Avoid over-fertilizing with nitrogen, which promotes foliage growth at the expense of flowers.
Banana Peel Tea：Steep chopped banana peels in water for 24-48 hours, strain, and use the liquid to water the base of the plant. This boosts potassium for prolific blooming. Discard peels in compost to avoid attracting pests.Pruning
- Pinch back young shoot tips in late spring to encourage a bushier habit;
- Deadhead spent flower spikes regularly to promote continuous blooming;
- Cut stems back to the ground in late winter or early spring before new growth begins.
