Are the white lumps furry-looking? That might mean mealybugs. Brown
lumps on ferns are usually scale insects. Both pests move very
little, do a lot of damage, and are difficult to control. Small
populations can be dabbed off with an alcohol-soaked cotton swab, but
larger infestations usually require an insecticide, and insecticidal
soap, or application(s) of dormant oil to smother the pests. My
advice would be to take an infested front to the best local nursery
you can find, get a firm diagnosis of the problem, and then look for a
product that will take care of the problem. Make sure what you use is
labeled for ferns. They can be very fussy about chemicals.
If some part of your plant is unaffected, you might want to divide the
plant and pot it up. That way you will have saved some of Gertie.
