Well, John, you made some good points, and had some good suggestions but you also raised some questions.
As I mentioned in my notes — at a time when we are trying to reduce the use of chemicals in general and specifically in the garden, you have repeated the idea of spraying and treating with chemicals a number of times in your article.
I would interested to know what your background is in horticulture and plant husbandry, and from where you have gathered your facts.
I am a professional gardener and have been for almost 40 years and find some of your statements questionable. Leaving a basis for discussion if you would like.
