Why are there orange spots on my Matgrass? Causes and fixes

Check these first

Inspect the undersides of the leaves for orange dust.
Check if the soil is staying wet for too long.

Likely causes

Rust fungus
Most likely
How to tell: You will see small orange or brown pustules forming on the leaf blades. These spots often appear after long periods of damp or humid weather.
What to do: Trim away the heavily infected leaves to stop the spread. Improve air circulation around the plant by thinning out crowded patches. Avoid overhead watering to keep the foliage dry.
Poor air circulation
Possible
How to tell: The plant looks damp and stagnant even when it has not rained recently. The spots might be concentrated in the center of the clump.
What to do: Move the plant to a spot with better natural airflow. If the grass is growing in a dense clump, divide it to give each section more space.

When to worry

You should worry if the spots are spreading rapidly across the whole plant. A few small spots are manageable, but a full infection can weaken the grass significantly.

Stopping it coming back

Ensure your Matgrass has plenty of space and avoid watering the leaves directly. Keeping the area tidy and free of debris helps prevent fungal spores from settling.
