Messenger – Growth Enhancer

Q: I heard you on your radio show discussing a product called Messenger to make tomato plants stronger. As novice growers, we have many questions about how to use it and how it works.

A: Messenger(tm) contains a special protein that causes a plant to believe it’s being attacked. As a result, the plant, be it tomato, petunia or turfgrass, thickens its leaves and puts insect- and disease-resisting chemicals in its cells. This is much the same effect as when humans receive a vaccine to guard against disease. Other chemicals, even aspirin, trigger this “systemic acquired response” when applied to plants. You can buy Messenger locally at Hastings Garden Center. Online, Gardens Alive ( sells the same product, renamed Green Guard.
