Cymbidium Yellow Bulbs and White Leaves: Too Much Sun in Australian Climate

Diagnosis: Excessive Light

Yellowing bulbs and white leaf tips in Sydney's California-like climate indicate too much direct sunlight. Cymbidiums love sun but have limits.

Leaf Color as Light Meter

• Large cymbidiums: light to medium green = correct light
• Miniature/Chinese cymbidiums: medium to semi-dark green = correct light
• Yellow/white = too much sun

Simple Fix

Move to slightly shadier spot or under tree canopy. Reduce direct exposure while maintaining bright conditions. "Most cymbidiums love sunlight but too much of a good thing is too much."
