Dust and Debris Accumulation

While not a biological pathogen, thick layers of dust on the waxy cuticle of Sedum adolphii can sometimes mimic a webbed appearance under certain lighting.

1 Gently wipe the leaves with a soft, damp cloth or use a soft paintbrush to remove the dust and debris from the waxy cuticle.

2 Inspect the undersides of the leaves and crevices closely for actual spider mites, as they produce much finer, more structural webbing than dust.
