Banana peel tea:Soak chopped banana peels in water for 3 days; dilute 1:10 for root drench to support bloom production without over-fertilizing
Pruning
  • Deadhead spent blooms to encourage extended flowering through early summer

  • Divide overcrowded clumps in early spring to promote healthy growth and spread
