Spider Mites on Junipers and Rosemary Decline: Diagnosis and Care

Evergreen/juniper shrubs show white cotton-like webbing on branches; rosemary plants have large brown sections.

Juniper/Webbing Issue

Fragile, sparse webbing suggests spider mites—microscopic pests requiring magnification for confirmation. Take a sample to a local nursery for ID. Regular spiders also create webbing but cause no harm.

Rosemary Browning

Without seeing the plant, prune out affected sections in case of disease. Rosemary prefers well-drained soil, full sun, and minimal water once established. Overwatering and poor drainage commonly cause root rot and dieback.
