I kind of have a thing about spraying anything
on my plants. Maybe it's a rational decision or maybe not ...
At the beginning of my rose life, so many chemicals were commonly used and one almost had to have a science degree to even begin to understand what was in the sprays. Many of those products that were once classified as "caution" .. the safest product to use, ... have been either reclassified as "dangerous" or taken off of the market because they are so toxic.
My decision was not to spray anything I don't understand. Just because someone recommends a spray, even if I do trust them, if I don't understand what I am doing, I am not going to use the product until I have done my own research.
When I use the word "understand", I NEED to know both the short-term and the long term impact of the spray on my garden plants and the environment.
