Two-Spotted Spider Mite Infestation

These arachnids thrive in the warm, dry conditions common for OT hybrids like 'Ria'. They pierce the lily's leaf cells to suck out nutrients, leaving behind fine silk webbing and stippled white spots.

Very Common

Tetranychus urticae (European Red Spider Mite)

A specific subset of spider mites that is highly prevalent in greenhouse-grown Liliums. The webbing becomes more dense as the population grows, eventually causing entire lily leaves to turn bronze and wilt.

Very Common

High Humidity/Fungal Mold Growth

While less common, extremely high humidity in stagnant air around the lily foliage can sometimes cause fine, white fungal mycelium that mimics spider mite webbing.

Common

How to confirm: Check if the 'webbing' is accompanied by fuzzy patches on the leaf surface rather than just silk strands between leaves.

1 Increase airflow around the lily foliage by using a small fan or spacing plants further apart to prevent stagnant, humid air.

2 Apply an organic fungicide to treat the fungal mycelium and protect the plant from further mold development.
