Yes, Hardscapes and rock areas definitely effect plant growth and photosynthesis. There are so many variables including the type of tree so there is no simple answer. Here is a link to a great master gardener document: Please email directly if you have more questions.

Thanks Susan, I had this opinion and disagreement with a contractor in Glenwood Springs who wanted to incorporate the thermal waters to keep a large parking lot snow-free. Thanks for the back up.
