Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often experienced by Gerbera daisies. They feed on the undersides of leaves, secreting silk that creates characteristic fine webbing around the leaf margins and flower buds.

Very Common

How to confirm: Hold a white piece of paper underneath a leaf and tap the leaf 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 greenhouse-grown Gerberas. High populations lead to dense webbing that can eventually cause the scarlet petals to wilt and leaves to develop chlorotic stippling.

Very Common

How to confirm: Inspect the undersides of the leaves for tiny, reddish or yellowish dots which indicate feeding sites.

warning

Extreme Low Humidity

While not a primary cause of webbing, extremely dry air can stress Gerbera daisies and accelerate the lifecycle of existing mite populations. This environmental stress makes the plant more susceptible to visible silk production.

How to confirm: Use a hygrometer to check if the ambient humidity is consistently below 40% in your growing area.
