Troubleshooting
Shark-Toothed Neoregelia problems — and how to fix them
Shark-Toothed Neoregelia (Neoregelia carcharodon) 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.
Brown serrated tips
Sharply toothed margins can brown if humidity is very low or water is high in fluoride. Use rainwater and maintain humidity above 50%.
Cup rot
Stagnant water in the large central tank rots the base. Empty and refill weekly, especially in warm weather.
Scale insects
Hard, limpet-like scales attach along the leaf midrib. Remove mechanically and treat with horticultural oil.
Pale, washed-out colouring
Insufficient light prevents the characteristic reddish centre flush. Move to a brighter spot away from direct harsh sun.
Root decay in heavy mix
This large bromeliad has relatively few roots; heavy compost suffocates them. Always use a very open, bark-dominant medium.
