Black, slightly raised spots that wipe off are likely scale insects. Treat by thoroughly spraying all surfaces with a mix of 1 part rubbing alcohol to 5 parts water plus a little liquid soap. Repeat in 5–7 days and monitor weekly. Well water is often hard (high minerals)—switch to distilled or filtered water to prevent further stress.
Early, thorough treatment prevents the sticky honeydew that attracts ants and sooty mold.
