Reviving Cold-Damaged Ground Orchids (Spathoglottis)

Ground Orchid Recovery After Cold Snap

A Miami gardener's Spathoglottis plicata (ground orchids) suffered severe damage after a single cold night. Leaves turned brown, blooms disappeared, and pseudobulbs appeared brown and shriveled. The plants face north and were fertilized two weeks prior.

Assessing Viability

Squeeze the pseudobulbs (corms) gently. Firm, solid bulbs indicate living tissue. If some are alive, reduce watering drastically—allow the medium to become almost dry between waterings. Resume light watering only when new growth emerges.

Care During Recovery

Feed lightly and regularly once active growth resumes. Protect from future cold: when temperatures below 45°F (7°C) are forecast, cover plants with blankets, sheets, or plastic. Ground orchids in Florida need this protection in northern regions.

Patience is key; recovery may take months, but healthy bulbs can regenerate.
