Care Guide
Water moderately during active spring growth and blooming; reduce as the plant dies back in summer.
Apply a light, phosphorus-rich organic amendment if soil is very poor.. As a legume, it fixes its own nitrogen; avoid nitrogen-heavy fertilizers which promote foliage over 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 in early spring to support bloom development. Avoid using raw peels directly on the soil to prevent pests.- Deadheading: Remove spent flower spikes if you wish to prolong the blooming period;
- Seed Saving: Leave some pods on the plant to mature and dry if you want them to self-sow for the following year;
- Cleanup: Pull up and compost the entire plant once it turns brown and dies back in the summer heat.
