Two-ranked Bromeliad problems — and how to fix them
Two-ranked Bromeliad (Aechmea distichantha) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Scale insects
Brown or white armoured scales cluster along leaf midribs and under bracts; wipe off with a cotton swab dipped in isopropyl alcohol and treat with neem oil if severe.
Cup rot (bacterial or fungal)
Stagnant water in the central cup encourages rot at the base of inner leaves; flush the cup with fresh water monthly and never leave standing water over winter in cool conditions.
Mealybugs
White waxy clusters appear in leaf axils; remove with alcohol-soaked swabs and treat with an insecticidal soap spray, repeating every 10 days until clear.
