How to Care for Dendrobium (Dendrobium orchid)

Korean name: 덴드로비움

Key facts

Care Guide

Detailed care guide

Dendrobium is an orchid whose flowers line up along jointed, cane-like stems. It wants more light than a moth orchid and needs a cool winter rest to flower again.

Watering

Water thoroughly when the bark or moss is almost dry — about weekly in spring and summer, every two weeks in winter. Don’t let water sit between the canes.

Light

Bright indirect light. It likes more light than a moth orchid, so a window behind a sheer curtain is ideal. Spring and autumn sun is fine, but midsummer direct sun scorches the leaves.

Humidity

It likes 50–70%. In dry winters use a humidifier or a pebble tray.

Temperature

It grows well at 18–28°C. From late autumn through winter keep it somewhere cool at 10–15°C so it sets flower buds. Don’t let it drop below 5°C.

A common first-timer mistake

Don't cut canes right after they finish flowering. They still store food, and some flower again the next year.

If you have pets

Dendrobium orchids are considered non-toxic to pets, though eating a lot may still upset a stomach.

Through the Seasons

New canes grow from spring through summer. Feed orchid fertiliser every two weeks and water generously. In autumn stop feeding, water less and move it somewhere cool. That cool rest is what brings flowers from late winter into spring.

Common Problems and Fixes

If it grows baby plants (keikis) on the canes instead of flower buds, the winter was too warm or too wet. Old canes shedding yellow leaves is normal; on new canes, suspect overwatering. Wipe off scale insects with a cotton swab dipped in rubbing alcohol.

Repotting and Propagation

Repot every two years, just after flowering, into fresh bark or moss. Keep the pot small relative to the roots. Once a keiki on a cane has roots 3–5 cm long, you can cut it off and pot it separately.

Who It's Good For

It suits anyone who received an orchid as a gift and wants it to bloom again year after year, and who has a bright window. A cool spot near a balcony in winter makes it easier.
