Having problems with your roses? UC ANR’s free publication, Roses: Diseases and Abiotic Disorder will likely have solutions to improve the health of your rose plants.
This publication covers many diseases caused by bacterial, fungal and viral pathogens as well as abiotic disorders. Abiotic disorders cause similar symptoms as disease, but damage is caused from chemical toxicities, mineral deficiencies, or environmental problems.
Regardless of cause, practical and wide ranging advice to asses and improve plant health is provided. Many photos are included.
