1. In the Master Gardener manual, it often refers to different regions, but I can't find where those regions are listed, nor a link to another website which clarifies the regions. Can you help me figure out in which region I am located in? 2. How can I figure out what zone I am in? 3. What do these zones mean? 4. Where can I find out the elevation of my house, so I can figure out what zone I am in? 5. What kind of plants do well in the zone that I live in?
