When to Uncover Bog Garden in Zone 5a

When to Uncover Bog Garden in Zone 5a

Remove mulch during a stretch of frost-free nights (likely April). Early emergers: flytraps, Darlingtonia. Frost risk lasts until late May.

Protection

  • Cover new growth with plywood on freeze nights (air gap insulates).
  • Black plastic works too.
  • Spray sulfur fungicide after uncovering.

Plants survive frost—just lose tender new leaves temporarily.
