Two-Spotted Spider Mite Infestation

The fine webbing is a hallmark sign of spider mites, which thrive in the warm, dry conditions preferred by Aeonium haworthii. These pests pierce cell walls of the succulent leaves to suck out nutrients, causing stippling and eventual leaf drop.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap the plant to see if tiny specks fall onto the paper.

Broad Mites

While broad mites are too small to be seen individually, they can cause structural changes and fine silken textures in some succulent species. They primarily target the growing points (meristems) of Aeonium, causing distorted or stunted new growth.

Common

How to confirm: Inspect the very center of the rosette for any signs of deformation or curling of new leaves.

1 Inspect the growing tips of the Aeonium for distorted or stunted leaves and apply an organic miticide to eliminate the mites and their eggs.

2 Prune away any severely distorted or heavily infested growth tips using sterilized shears to prevent the mites from spreading to healthy parts of the plant.

3 Improve airflow around the plant and avoid overcrowding to make the environment less hospitable for mite populations.

High Humidity and Mold/Fungal Growth

In rare cases, extremely high humidity combined with poor airflow can cause fine fungal hyphae to appear as a web-like structure on the leaf surface. This is less common for Aeoniums but can occur if the plant is kept in an enclosed terrarium without ventilation.

Rare

How to confirm: Check if the 'webbing' is actually fuzzy or appears more like a thin layer of mold rather than structured silk.

1 Improve airflow around the plant by removing it from enclosed terrariums and ensuring it is in a well-ventilated area to prevent fungal growth.

2 Apply an organic fungicide to treat the fungal hyphae and protect the plant from further spread.
