Two-Spotted Spider Mite Infestation

The presence of fine webbing on Gerbera leaves is a classic sign of spider mites, which thrive in the warm, dry conditions often found in greenhouse settings. These arachnids pierce plant cells to feed, causing stippling and eventual leaf drop.

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.

Tetranychus urticae (European Red Spider Mite)

This specific mite species is highly prevalent in Gerbera production and specializes in creating dense silk webs across the foliage to protect colonies. As they consume chlorophyll, the red/bicolour petals may lose their vibrancy due to plant stress.

Very Common

How to confirm: Inspect the underside of the leaves for tiny reddish or yellowish dots that move slowly.

3 Carefully wipe the leaves with a damp cloth to physically remove webbing and any remaining mite colonies.

warning

Extreme Low Humidity

While not a direct cause of webbing, very low humidity levels trigger the physiological stress response in Gerbera daisies that accelerates mite reproduction and web production. This environment allows the silk structures to remain intact rather than breaking down.

Common

How to confirm: Check if the surrounding air is excessively dry and if the leaf edges are also showing signs of desiccation.
