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 Gerbera greenhouses. These pests pierce plant cells to suck out contents, leading to stippling and eventual leaf drop.

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

2 Increase humidity around the plant and wipe leaves with a damp cloth to physically remove webbing and disrupt the mites' dry habitat.

3 Monitor soil moisture levels to ensure the environment does not become too dry, which encourages mite reproduction.

Tetranychus urticae (European Red Spider Mite) Outbreak

In high-humidity environments like those required for Royal Lemon Gerbera, certain mite species can create dense webbing to protect themselves from predators. This leads to chlorosis (yellowing) of the leaf tissue between the veins.

Very Common

How to confirm: Inspect the undersides of the leaves for tiny, bright red or orange moving dots.

3 Gently wipe the leaves with a damp cloth to physically remove webbing and any remaining mites from the undersides of the foliage.

warning

Extreme Low Humidity / Desiccation

While webbing is almost always biological, severe lack of humidity can cause the fine hairs (trichomes) on certain Gerbera varieties to trap dust and debris, creating a web-like appearance. This stress often coincides with mite outbreaks.

Common

How to confirm: Check if the surrounding air is significantly below 50% humidity and if leaf edges are turning crispy and brown.

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

2 Increase ambient humidity around the plant using a pebble tray or a fine misting tool to prevent further desiccation.
