Margo and Breeze, I'm glad you liked the Messenger. I use Messenger and really like it. But, you should know that I am a scientist for the company that makes it...I could be a little biased. :) That is why I have those sample packets. You probably haven't seen it around because it is only available in nurseries in big cities or on line. The technology is from Cornel University. The active ingredient is "harpin protein". Harpin proteins are proteins that are secreted by pathogenic bacteria. The harpin protein in Messenger comes from the bacteria that causes fireblight in apple trees. These harpins don't cause diseases, they trick the plant into thinking that there is a disease present and cause the plant to mount its own natural defense. So, Messenger causes plants to be healthier without chemicals. But I like it because it also makes things bloom. I guess that when a plant thinks that there is a disease present it goes into reproductive mode so that it can carry on the species. If you have a greenhouse then you can try it this winter, otherwise save it till spring. That packet mixes up in 1 gallon of water and sprays 1000 ft2. Spray on the leaves. So it goes a long way. Should be enough to spray your whole flower bed. I retreat about once a month. Hope you like it.
Robin
