Orchid Leaves: Turning Yellow
Why are my orchid leaves turning yellow?
If your bottom orchid leaf has turned yellow it does not necessarily mean your orchid is sick or dying. You can not prevent your bottom orchid leaves from ultimately turning yellow because this is the natural cycle of an orchid.
You see orchids work in balance between new leaves, new roots and blooms. In order for blooms to appear in the winter and spring, new leaves and new roots need to grow in the summer and fall. Older leaves, over time, will die back naturally as will new leaves appear (shown below). From this new growth will come the next bloom!
So when your bottom orchid leaves turn yellow and fall off this can be a good sign! It means your orchid is following natures cues and preparing for new growth.
Okay so what to do with the yellow orchid leafs?
1. Do nothing and wait. The orchid will eventually shed the leaf itself and seal off the area that it fell from.
2. Cut it off. Use a clean tool to avoid the possible spread of disease. Apply cinnamon (yes, the common household spice – it’s a natural fungicide) to the area you just cut as a preventative measure against any possible infection that may try to set in.
When to actually worry –
- If your orchid drops many leaves very suddenly.
- If they are dropping from the top of an orchid as shown below and/or you see dark slimy spots.

- If your leaves are turning really dark please click on my post “Orchid Light Requirements.”
Hope that Helps,
