When designing a privacy hedge, its a good idea to use multiple species of shrubs. The ficus whitefly destruction was an example of what can happen when we have a monoculture (one plant species in a hedge). I now see a replacement monoculture of Clusia (pitch apple) and hopefully we won’t have a new Clusia insect or disease which will wipe out these new hedges. For longterm sustainablilty, think of hedges composed of multiple-species to avoid pest ruination (an IPM tactic)!
See native plant selection ideas in our new video filmed at the Naples Botanical Garden with Chad Washburn:
Sweetpotato whitefly (Photo by Jeffrey W. Lotz, FDACS)- be on the lookout for the new Q strain, especially on hibiscus, lantana and crossandra. This one can be a major problem on 100’s of species of vegetables and ornamentals.

Oleander caterpillar numbers seem to be on the increase compared to the last few years. If you see these beautiful, wasp-like moths (above), look for the clusters of eggs (above) they are depositing and clip the leaves off! Repeating generations of caterpillars can wreck the appearance of an oleander hedge! The caterpillars (below) are a day-glow orange with soft black hairs.
