I am trying to understand my garden's microclimates.
I've read that cold air drains down slopes and accumulates in pockets at the bottom. But I have also read that protected areas adjacent to brick walls can be much warmer that the other areas.
I would like to find the best spot to plant a heat-loving tree. Can you please help me sort this out? This is a picture of my garden, looking NE.
Thanks for any clarification!
