But the fact the hyacinth grew well and then failed completely makes me think something else is involved. There are parasitic insects that have been released in Florida in an effort to control hyacinth, which clogs waterways across the entire state. The insect controls have not worked in nature, but there are times when the bugs reportedly do work to decimate small, localized populations. The ones I'm familiar will create chewed areas at the base of some leaves, and even inner leaves will rot off at the base, not just old outer leaves. Perhaps something similar is in your area. |
