Care Guide

Watering

Water regularly during early growth, reducing frequency once established and blooming.

Fertilization

Apply a light, balanced organic fertilizer once seedlings are established.. Over-fertilizing can lead to excessive 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 plants to promote vibrant blooms. Discard the peels in compost to avoid attracting pests.
Pruning
  • Deadheading: Remove spent flowers regularly to prevent early seed formation and prolong the blooming period.
  • Seed Collection: Leave the final blooms of the season on the plant to develop into seed pods if self-seeding is desired.
  • Clearance: Pull up and compost the entire plant once it turns brown and dies back at the end of summer.
