Thrips on Gladiola

Anonymous added on October 15, 2011 | Answered

I have a problem with thrips on my gladiola plants. Can/should the corms be soaked/immersed in an insecticide before storing for the winter? If so, what would you recommend for soaking? I have been told, Lysol, bleach, and others - but not sure I can safely use any of these or maybe an insecticide. Okay to soak? In what?

Yes, it is fine to soak the corms in this type of solution. It makes for healthier plants the next year. A solution made with Lysol is most commonly used, but any disinfectant can be used. A very weak bleach solution would work as well.
