Do Oncidiums need a winter rest?
Metalhalide and sodium-vapor bulbs also provide sufficient light without needing to be so close to the plants.

Why is my orchid bulb shriveling?
The shriveled pseudobulbs mean that the water within them is being used to nourish the plant due to lack of water at the roots, whether they just haven’t received it or have rotted and died. Corrugations at the leaves are caused by a non-constant watering schedule, ie you water lots for a period, then stop watering.
What is the best medium for Oncidium orchids?

What is the best potting mix for Oncidium orchids?

Why are my Oncidium leaves turning yellow?
This is normal and natural. Sometimes a stress, such as repotting, will cause an orchid to lose a leaf or two on an old pseudobulb. The orchid in the picture, an Oncidium, is doing just that. After repotting it has chosen to shed the leaves on its oldest pseudobulb (often called a “back bulb”).
How do you care for an Oncidium orchid?
