I had tomato blight last year and heard that I should clean my garden tools and tomato cages before they used again this year. What do I use to clean them?

Expert Response

We recommend you use one of the following three choices-10% bleach solution, rubbing alcohol/70% or 1% alkyl dimethyl benzyl ammonium saccharinate/Lysol all purpose cleaner.   See website for additional details.

It is also a good idea to rotate tomatoes every couple of years.  Buying resistant varieties is also a preventive measure:
