Care Guide

Watering

Keep soil evenly moist but not waterlogged

Fertilization

Diluted balanced liquid feed every 2 weeks. Avoid over-fertilizing, as it can lead to leggy stems and reduced flowering

Banana peel tea:Chop 1–2 banana peels, soak in 1 liter of water for 3 days, dilute 1:20 with water before applying as a root drench; discard solid peels to prevent pest infestations
Pruning
  • Trim back overgrown mats in early spring to maintain a neat, compact form
  • Remove yellowing or damaged leaves to improve airflow and reduce disease risk
  • Pull up unwanted spreading stems to control its invasive growth habit in garden beds
