Apply diluted organic feed once monthly. Use low-nitrogen feed to support bloom production without excessive foliage growth

Banana peel tea:Chop 2–3 banana peels, soak in 1 liter of water for 3 days, dilute 1:10 with water for root drench; discard solids to avoid odor and pest attraction
Pruning
  • Trim overgrown trailing stems in late summer to maintain compact form
  • Remove dead or yellowed foliage in early spring to stimulate new growth
