Care Guide
Water deeply once a week, allowing the top inch of soil to dry out between waterings.
Apply a balanced fertilizer early in the season to encourage healthy foliage and stem development.. Avoid over-fertilizing with nitrogen, which promotes leaves 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 to boost blooming. Discard solids in compost to avoid attracting pests and odors.- Deadhead spent flowers regularly to encourage continuous blooming;
- Remove the entire plant at the end of the season if self-seeding is not desired;
- Thin out crowded seedlings in spring to ensure good air circulation.
