I have a small (my first) 2 ft. high pink Hibiscus on my deck this Summer.
It was going great until about 3 weeks ago, when I noticed that the blooms
are wilted around the outside edge about 1/8 inch. I water it regularly, the
pot has drainage, although, in NJ this Summer, it has been really hot. I was
hoping it would improve when the weather turned cooler, but I still get this
edge wilt going on.
Any ideas what could be wrong?

The blooms on tropical hibiscus varieties may rot before opening in
ultra high humidity and temperatures.
