Orchids adapt to local seasons. NorCal winter = your winter.
| Group | Winter Temp | Water | Location |
|---|---|---|---|
| Cymbidiums | Mid-30s°F OK | Barely moist | Outdoors |
| Dendrobiums | Evergreen: barely moist Deciduous: dry | Per type | Indoors <50°F nights |
| Cattleyas (inc. Epicatts) | Indoors <50°F nights | Barely moist | Indoors |
| Baby Cattleyas | Indoors <50°F | Barely moist | Indoors |
| Phalaenopsis | >55°F always | Barely moist | Indoors year-round |
Eave cover = good. But cold + wet = rot. Move tender types indoors when nights <50°F.
Stop fertilizing most by fall. Resume spring with new growth.
High if you respect temp thresholds. Cymbidiums are toughest; Phals most tender.
