Two-Spotted Spider Mite Infestation

The fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often experienced by Lilium species. These pests pierce the lily cells to suck out sap, leading to stippling and eventual webbing coverage.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap it sharply to see if tiny crawling dots fall onto the paper.

1 Immediately spray the lily leaves, including the undersides, with an organic insecticide to kill existing mites and larvae.
2 Increase humidity around the plant and ensure the soil remains moist, as spider mites thrive in dry environments.
3 Monitor soil moisture levels regularly to prevent the dry conditions that trigger mite outbreaks.

Southern Yellow로 Spider Mite (Tetranychus urticae)

In many lily varieties, specific mite species create dense silk webs around the leaf margins and stem junctions to protect their eggs. This is often triggered by low humidity levels around the Lilium bulb.

Very Common

How to confirm: Inspect the underside of the leaves specifically for small, yellowish-white dots (stippling) beneath the webbing.

1 Apply an organic miticide or insecticide spray to the plant to eliminate the spider mite population and destroy their eggs.
2 Increase the ambient humidity around the lily to discourage future mite infestations and prevent the silk webbing from forming.
3 Carefully wipe the leaves with a damp cloth to physically remove the webbing and any remaining mites from the stem junctions.

Extreme Environmental Desiccation

While less common as a direct cause of 'webbing,' extreme lack of humidity can cause certain fine fungal hyphae or dust to appear web-like on the surface of lily foliage. This often coincides with mite outbreaks due to dry air.

Common

How to confirm: Check if the surrounding air is significantly below 40% humidity and if the leaf edges are turning brown/crisp.

1 Inspect the undersides of leaves for tiny moving dots to confirm if the webbing is caused by spider mites, which thrive in dry conditions.
2 Increase ambient humidity around the lily to prevent further desiccation and discourage mite activity.
3 Use a moisture meter to ensure the soil remains consistently moist but not waterlogged, preventing the extreme dry spells that trigger these symptoms.
