Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often experienced by OT hybrids like Saronno. They pierce plant cells to feed, leaving behind fine silk webbing as they create colonies on the undersides of lily leaves.

Very Common

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

Tetranychus urticae (European Red Spider Mite)

This specific mite species is highly prevalent in greenhouse-grown lilies and produces dense webbing that can eventually cause the lily foliage to turn chlorotic or bronze.

Very Common

How to confirm: Inspect the leaf undersides for tiny reddish or orange moving specks near the silk strands.

High Humidity/Microclimate Mold (Secondary)

While webbing is characteristic of mites, extremely high humidity trapped within dense Saronno lily foliage can sometimes cause fungal hyphae to appear thread-like and web-like across leaf surfaces.

Common

How to confirm: Check if the 'webbing' feels organic/fuzzy rather than structural/silky and if there are dark necrotic spots nearby.

1 Inspect the undersides of leaves for tiny moving dots or eggs to confirm if the webbing is spider mites rather than fungal hyphae.

2 Improve airflow around the dense foliage by pruning away any dead or overly crowded leaves to reduce trapped humidity.

3 Apply an organic miticide/fungicide spray to eliminate both potential spider mites and secondary fungal growth.
