Should I cut off the yellow leaves?

Yes, you can trim them off with clean scissors once they are mostly yellow. This keeps the plant looking tidy and prevents potential fungal issues.

Does yellowing mean my orchid is dying?

Not necessarily, as it is often a sign of a simple care mistake. If you catch it early and fix the moisture balance, the plant will usually recover.

Western marsh orchid: yellow leaves, causes and fixes

Check these first

Touch the soil to see if it feels soggy or bone dry.
Inspect the drainage holes to ensure they are not blocked.
Check the base of the stem for any signs of mushy rot.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow and soft, often starting from the base of the plant. The soil may smell sour or feel like a swamp.
What to do: Stop watering immediately and let the top inch of soil dry out. Ensure your pot has drainage holes so extra water can escape. If the soil stays wet for more than 5 days, repot into a fresh, well draining mix.
Nutrient Deficiency
Possible
How to tell: The leaves lose their deep green color and turn a pale yellow, often affecting older foliage first. This happens when the soil has been depleted of minerals over a long growing season.
What to do: Apply a balanced, water soluble fertilizer diluted to half strength. Feed the plant once every 4 weeks during the active growing season. Do not fertilize during the winter dormancy period.

When to worry

It is normal for the oldest bottom leaves to yellow and die back as the plant prepares for winter dormancy. Be concerned if the yellowing spreads rapidly to new growth or if the stem feels soft.

Stopping it coming back

Maintain a consistent watering schedule that keeps the soil damp but never waterlogged. Use a potting mix specifically designed for moisture loving orchids.
