Are your lantana looking rusty brown like a fungus has attacked them? Well it’s not a fungus it’s a lace bug. These are common this time of year to attack lantanas leaving them looking ugly and half dead. This problem is easily fixed by pruning back the ugly plant either one third to half way depending on the damage. Rake up the bad leaves which will be eliminating the majority of the bugs, fertilize with your favorite plant food and water in, then spray with a multi purpose insecticide like Cyonara Lawn & Garden or Organically with Spinosad Insect Control. The plant will quickly recover like nothing ever happened putting on a flush of new growth and blooms.
