Re: Fighting the fuzz

Hi everyone
  I agree with Shelley....the "Safer Soap" type-soaps work well on scale but you need 2 or 3 applications at intervals of 10-14 days for effective treatment. It doesn't seem to harm the ferns as long as they are well watered before (i,e, not bone dry compost when spraying) and you stick to the recommended dilutions.
  Good luck!

  Hi All!
Won't use Orthene. Nasty stuff.
I've had great success with Safe-T-Side oil on many ferns (not maidenhairs).
Slight damage, but kills the scale.

Also, for earwigs, cutworms, sowbugs, pillbugs, and slugs I use a new 
product (to me, anyway) Sluggo-Plus. It contains spinosad, a 
naturally occurring soil dwelling bacterum and iron phosphate. So 
far it's been effective.
