Hibiscus Left Out in Freeze: Scratch Test for Survival

Viability Test

Scratch bark near base. Green cambium = alive. Brown = dead.

If Alive

  • Keep in shade, water moderately (not wet).
  • Wait for new growth before moving to sun.

Reality Check

28°F likely killed a tropical hibiscus in upstate NY. But verify before giving up.
