Cymbidium Orchid Care: Light, Water and Flowering

Understand a cymbidium orchid’s need for light, drainage, airflow and suitable day-and-night conditions.

A different orchid with different needs

Cymbidiums are known for their sprays of flowers and strappy leaves. Standard and miniature forms vary, so ask about your particular plant rather than treating every orchid in the home in the same way.

Light without scorching

Provide plenty of light while protecting the plant from harsh midday sun. Morning light or a sheltered, bright position can be useful, depending on the site. Introduce a plant gradually to a brighter position rather than moving it abruptly into strong sun.

Temperature and airflow

Cooler nights can be important to flowering, while very warm nights may make flowering more difficult for some varieties. Protect the plant from frost and extremes, particularly when it is in bud or flower. Maintain airflow around the foliage and flowers.

Water without waterlogging

Water according to the condition of the growing medium, the season and the plant’s activity. Do not let the pot remain soggy, and do not rely on a fixed weekly schedule regardless of the weather. Let excess water drain and empty any outer pot or saucer.

Feeding through the growth cycle

Use an orchid fertiliser suited to cymbidiums and follow its instructions. Requirements can change through the growth and flowering cycle. Ask us or an orchid specialist about a suitable feeding programme for your plant and local conditions.

When to repot

Repot after flowering when needed, particularly if the medium has broken down or the plant has outgrown its container. Use a suitable open orchid mix. Avoid disturbing a healthy plant simply because a calendar date has arrived.

If it grows but does not flower

Review light levels, night temperatures and the growth cycle before changing fertiliser. These factors work together; extra feeding alone is not a reliable solution.
