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 Oriental lilies. These arachnids pierce the lily's cell membranes to feed, causing stippling (tiny white dots) on the leaves.

Very Common

How to confirm: Tap a leaf over a white piece of paper to see if tiny moving specks fall off.

1 Apply an organic miticide spray to the plant to eliminate existing spider mites, eggs, and larvae.
2 Increase humidity around the lily by using a fine mist spray to create an environment less favorable to mite reproduction.
3 Monitor soil moisture levels to ensure the plant is not suffering from drought stress, which can exacerbate mite infestations.

Tetranychus urticae (European Red Spider Mite)

A specific subset of spider mites that is highly aggressive on Lilium species during summer heat. They create dense silken webs to protect themselves from predators and environmental stress.

Very Common

How to confirm: Inspect the undersides of the lily leaves for small, reddish-brown clusters or dots.

1 Immediately spray the plant with an organic miticide or insecticide to eliminate the spider mite population and destroy their webbing.
2 Increase humidity around the lily by using a fine mist spray to make the environment less hospitable for spider mites.
3 Carefully prune and dispose of any heavily infested or dead foliage to prevent the mites from spreading to healthy parts of the plant.

High Humidity/Microclimate Mold (Secondary)

While less common for webbing, extreme humidity in dense lily beds can cause fungal hyphae to appear thread-like. This is usually accompanied by leaf discoloration rather than just silk.

Common

How to confirm: Check if the 'webbing' feels more like fuzzy organic growth rather than fine, structural silk.

1 Inspect the plant closely for moving pests like spider mites; if tiny insects are present, treat the foliage with an organic insecticide/fungicide spray.
2 Improve airflow around the lily bed by pruning dense foliage and ensuring plants are not crowded to reduce the microclimate humidity that fosters mold.
3 Monitor soil moisture levels to ensure the base of the plant is not staying excessively damp, which can exacerbate fungal growth.
