Overwintering Dwarf Crepe Myrtle Seedlings in New York

Dormancy Is Essential

Dwarf crepe myrtles are deciduous; they need a cold dormancy period (hours at 40°F). Indoor warmth breaks dormancy, causing weak growth.

Correct Approach

  • Move pots to unheated garage or basement.
  • Water weekly to prevent desiccation.
  • If in Long Island/SE NY, may survive outdoors next spring.
  • In colder areas, keep potted and protected.
