Zahn's Guzmania problems — and how to fix them
Zahn's Guzmania (Guzmania zahnii) 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.
Fading leaf stripes in low light
The distinctive reddish striping on the leaves weakens noticeably when the plant is kept in dim conditions; move to a brighter spot with indirect light to maintain the ornamental foliage pattern.
Root rot from overwatering the potting medium
Overwatering the mix rather than managing the cup leads to anaerobic root rot; the potting mix should approach dryness between waterings while the cup remains filled.
Mealybugs at leaf base
Mealybugs accumulate where leaves meet the stem base; inspect regularly and treat with neem oil or isopropyl alcohol swabs at first sight.
