Why Cymbidiums Don’t Flower

This deep dive explains why Cymbidium orchids sometimes fail to flower despite producing healthy foliage and new growth.

The Problem

Cymbidiums may grow strongly for extended periods without producing flower spikes.

Seasonal Signals

Flowering depends on environmental cues rather than plant size alone. Cymbidiums require a shift from warm daytime growth to cooler nights to initiate spikes.

Temperature Limitation

If nights remain warm, the plant may continue vegetative growth without transitioning to flowering.

Light Limitation

Insufficient light can suppress flowering even when temperature conditions are otherwise suitable. Plants kept too shaded often remain dark green and non-flowering.

Summary

Failure to flower is usually caused by missing environmental signals rather than poor plant health or nutrition.
