    Hi Norman, and thanks a bunch for this great article. I love zinnias, I have them all over my garden. They are beautiful flowers and I agree Zinnias are a must! I’ll be using all of your tips for my flowers, thanks to you. My zinnias are healthy right now but I’ll keep an eye on them to make sure garden insects stay away.

    Just one question: Which soap liquid do you suggest? Just a regular dishwashing liquid or something else?

    Thanks again, cheers
