Hi guys, I also posted in the "Beginner Landscape" forum, but I do know there are some VERY knowledgeable folks in our California forum, so, posting here too!

I'm 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've ALSO read that protected areas adjacent to brick walls can be much warmer than other areas, sometimes a whole zone warmer. (?)
I would like to find the best spot to plant a heat-loving tree and heat loving/tropical plants. Can you please help me sort this out? This is a picture of my garden, looking NE.
Thanks for any clarification, I would love to learn more about this!
