Winter has really began to set in now.
Orchids need extra care over the cooler months to ensure they not only survive, but also thrive.
To protect your orchids over winter, keep them out of frost, shelter them from cold winds, and drastically reduce watering.
Because the potting mix stays wet longer in cooler weather, cold, soggy roots are the biggest threat.
Adapt your care routines to protect your orchids:
Move to a Safe Spot:
Relocate sensitive tropical orchids (like Moth orchids / Phalaenopsis) indoors or to a heated greenhouse. Hardy outdoor varieties (like Cymbidiums) can stay outside, but must be raised off the ground and sheltered from cold winds and driving rain. Use frost cloth if there is a risk of frosts and you are unable to relocate to a sheltered spot.
Watch the Temperature:
Never let temperatures drop to freezing. While some orchids tolerate slight chills, keep tropical varieties ideally above 15°C.
Keep all plants away from drafty windows where condensation can freeze on the leaves.
Drastically Reduce Watering:
Cool, wet roots easily develop root rot. Only water when the potting medium is completely dry. If your home is heated and very dry, a gentle misting or a pebble tray can help boost humidity without drenching the roots. For outdoor plants, choose a day that your washing would dry to water. This ensures the media is able to dry out before getting too cold again at night.
Decrease Fertilizer:
Since growth slows down, stop feeding entirely or use a diluted, half-strength feed only once a month. Resume normal feeding in early spring.
Know your orchids:
As orchids come from many different climates and environments, it helps to learn about the individual natural requirements for the type of orchids you grow. For example, while Cymbidiums tolerate the colder months fairly easily, the same cannot be said about Phalaenopsis orchids.
Discussion with other club members is a great way to learn how to protect your orchids within you local environment.
