Two-Spotted Spider Mites (Tetranychus urticae)

Spider mites thrive in the warm, dry conditions often experienced by Oriental Lilies, feeding on the undersides of leaves and injecting toxins that cause stippling. The fine webbing is a defensive silk structure used to protect their colonies and move across the foliage.

Very Common

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

1 Immediately spray the plant, focusing on the undersides of the leaves, with an organic miticide to kill existing mites and larvae.

Cyclamen Mites (Bre Pseudophylla)

While more common in Cyclamens, these mites can affect Lilium species and cause similar fine webbing and leaf distortion. They tend to target the newer, tender growth of the lily bulbs and foliage.

Common

How to confirm: Inspect the base of the lily leaves and the bulb area for any unusual swelling or concentrated webbing.

2 Prune and dispose of any heavily distorted or webbing-covered new growth to prevent the mites from spreading to healthy parts of the lily.

3 Increase airflow around the plant and monitor the underside of leaves regularly using a magnifying glass to catch early infestations.

warning

High Humidity with Lack of Airflow

While not a direct producer of silk, extreme humidity combined with stagnant air can cause certain fungal molds to create fine, hair-like structures that resemble webbing on the leaf surface.

Common

How to confirm: Check if the 'webbing' is actually fuzzy mold and see if it disappears when you increase air circulation around the plant.

1 Increase air circulation around the lily by using a small fan to prevent stagnant, humid air from settling on the foliage.

2 Apply an organic fungicide to treat the hair-like fungal structures and prevent further spread of mold.
