Dendrobium Orchid Care: Check the Type Before Winter

Dendrobium is a huge orchid genus, with upright canes and flowers that vary from one type to another. Ask for the species or hybrid name when you buy one: some keep their leaves, while others shed leaves and need a drier winter rest.

Bright light, airy roots

Give bright, filtered light and good air movement. Plant in an orchid bark mix and a small pot that fits the roots. Ordinary dense houseplant soil stays wet around epiphytic roots. The pictured plant is a cultivated Dendrobium, not a promise of the same flowers on every species.

Water for the growth stage

While new shoots and roots are growing, water thoroughly when the bark has begun to dry, then let it drain. A dormant, deciduous type may need much less water after growth finishes. Watering every Dendrobium by the same weekly rule can harm both active and resting plants.

After flowering

Leave green canes in place: they store resources and some types flower from older canes. Remove a cane only when it is fully dead. If the orchid does not rebloom, identify its type and check light and seasonal rest before adding fertilizer. Watch for mealybugs around cane joints.

Pets

ASPCA includes Dendrobium among orchids considered non-toxic to cats and dogs. Keep fertilizers, treatments and any wire supports away from pets.
