Donnell Smith's Guzmania problems — and how to fix them
Donnell Smith's Guzmania (Guzmania donnell-smithii) 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.
Stagnant tank water
Water left too long in the cup becomes anaerobic and promotes bacterial rot and pest breeding. Flush the central cup with fresh water every 7-10 days.
Root rot
Develops if the substrate stays wet. Ensure the potting medium is free-draining and water the soil only when the upper layer is dry.
Brown leaf tips
Usually indicates fluoride or salt build-up from tap water. Use rainwater or filtered water for the central tank and soil.
Failure to rebloom
Like all bromeliads, the mother rosette flowers once then dies. Pups (offsets) from the base will become the next generation of flowering plants.
Scale insects
Treat with dilute neem oil or wipe with isopropyl alcohol on a soft cloth.
