Banana peel compost tea:Compost banana peels for 2–3 weeks, steep in water for 3 days, dilute 1:20 with water before applying as a root drench to avoid nutrient burn
Pruning
  • Deadhead spent blooms regularly to encourage prolonged flowering throughout the growing season
  • Trim back leggy stems by one-third in mid-summer to promote bushier, more compact growth
  • Cut back to basal growth in late autumn to prepare the plant for winter dormancy
