Spotted Neoregelia (Neoregelia tristis) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Water left standing in the cup for more than 10 days can become anaerobic and support rot-causing bacteria or mosquito larvae; flush the cup completely with fresh water at least once a week.
