💡 Pro Tips For Comparing These Plants

Four O'Clock Care Tips

Four O'Clocks are primarily outdoor plants and require full sun to thrive. Growing them indoors is challenging due to their high light requirements and potential for pest infestations. They also spread via tuberous roots, which can quickly outgrow a container. Indoor flowering is unlikely.

  • Plant in well-draining soil to prevent root rot.
  • Provide full sun for best flowering.
  • Deadhead spent flowers regularly to encourage more blooms.
  • Protect from strong winds, which can damage the delicate stems.
  • Monitor for pests like aphids and treat promptly.
❄️ Winter: In colder climates, dig up the tubers and store them in a cool, dry place over the winter. Alternatively, treat as an annual and replant in the spring.
☀️ Summer: Provide consistent moisture during the hot summer months. Deadhead spent flowers to encourage more blooms. Monitor for pests and diseases.

Lady's Mantle Care Tips
