Is This Orchid Mold or Something Else? 3 White Fuzz Culprits
Sometimes there’s a lot more growing inside the potting medium than we would like to admit. Bacteria and fungi are more common than we realize. Yet inside the potting medium, white fuzz is never a good sign. A white, fuzzy cotton-like growth starts slow, usually in new medium right after an orchid repot. This powdery, spiderweb growth appears out of the blue. It looks like white cotton, but can also have projections like a web. This white fuzz in the orchid pot, whatever it is, needs to go.
The white fuzz that appears to be cotton inside the orchid potting medium can be either orchid mold, powdery mildew, or mealybugs. In time, these three components will prevent the growth of a healthy orchid and need to be treated immediately.
Some orchids have hairs on their roots and these can be mistaken for fungus. Orchids that are terrestrial or semi-terrestrial have this in common. Paphiopedilums, for example, will have fuzzy roots. Oncidiums will have somewhat fuzzy roots. They look like a thicker root covered in fungus, but that is their normal state. Other orchids have small hairs that will uniformly cover the extension of your root, looking like polka-dot patterns of white dots on green roots.
Before you unpot, treat with a pesticide, and get nervous about your “dying orchid”, do a quick search to see what the normal roots look like in your orchid. I only say this because I did this as a beginner. To my shame and embarrassment, the orchid was indeed fine.
In this article, you’ll learn to differentiate what white, fuzzy, cotton-like creature is on your orchid roots and inside the potting medium, how to eliminate it, and how to prevent it from coming back. In all the three possibilities, your orchid will not die immediately, but if left untreated over several months, there is no remedy to salvaging what’s left of the roots and leaves. Let’s look at these items one by one.

This RU-vid Channel is the by-product of extensive research on how to recreate that environment inside my home.
By no means do I consider myself an expert but I'm an avid learner and willing to share the little I know with others. There are thousands of different ways to care for orchids, and the more we share, the more we learn.
What started out as a hobby has now grown into a passion, producing an online resource of quality information on how to connect with nature.
