I have a deep pink peony that are very slow to grow and bloom just bc there is a big tree in the way. All of the others do great, BUT, I read "full sun" and planted MINE that way, just like the others the somebody had planted on my property were ALSO planted right, in full sun.
I watched a gardening program recently, and the host interviewed a guy with a horticulture degree who talked about how his first lecture was contradicted by some old gardener in the audience. His balloon deflated. In the ensuing years he wondered if the common gardener's advice was wright or wrong. BEING a Scientist he decided to use the Scientific Method and experiment with all of the gardening advice that came his way, especially regarding insect control. He took his results to a book where he proves them right or wrong by way of 100% results. That doesn't mean that his methods will eradicate 100% of the bad bugs, but they are successful and he talked about how too much of one product and not enough another will not produce the result you want.
Your thread made me think of this. I am Also a result oriented gardener. If it doesn't work, I like to find out what DOES work. I have wasted too much $money on the wrong products or plants zoned for a warmer zone to waste any more.
Btw, as soon as I can dig the new hole that peony is moving to full sun at my DD's house!
