Two-Spotted Spider Mite Infestation

These microscopic arachnids pierce the cell walls of Lilium OT Bombini leaves to feed on sap, leaving behind characteristic fine silken webbing as they move across the foliage. High temperatures and low humidity often trigger outbreaks in Oriental hybrids.

Very Common

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

1 Apply an organic miticide/insecticide spray to the foliage to eliminate the spider mite population and destroy any remaining eggs.

2 Increase local humidity around the lily to make the environment less hospitable for mite outbreaks, as they thrive in dry conditions.

Tetranychus urticae (European Red Spider Mite)

Similar to the two-spotted variety, these mites thrive in dry environments and create dense webbing that can eventually lead to bronzing or stippling of the lily leaves. This is particularly common in greenhouse-grown Lilium OT cultivars.

Common

How to confirm: Inspect the undersides of the leaves for small reddish or yellowish specks near the web junctions.

warning

Edema (Physiological)

While not a direct cause of webbing, irregular watering in Lilium OT Bombini can cause cells to burst; if these ruptured cells are then colonized by secondary organisms or covered in dust/exudate, it may visually mimic fine debris or light silkiness.

Common

How to confirm: Look for small, blister-like bumps on the leaf edges that have turned brown and corky.

2 Inspect the plant closely for actual spider mites, as the webbing may be a secondary infestation; treat with an organic insecticide if pests are found.

3 Ensure the plant has adequate airflow and proper drainage to prevent the moisture buildup that leads to edema.
