Lantana/Hibiscus Pest/disease Problems

Question

I’ve attached some photo’s of my Lantana and Hibiscus plants that have either a pest or disease (or both) problem. Are you able to tell me which plant has what? Thanks !

Answer 1

This is a fungal infection from soils that do not get a chance to dry out thoroughly between watering, or soils that are too compact and remain saturated under the surface.

Fungicides will be in order:

Next, adding earthworms will be beneficial to breaking up compact soils, and adding nutrients back to the area.
