Solar gain isn't a problem in this location. It only gets morning and early afternoon sun most of the year, and the siding is light beige vinyl. I actually have in mind to use this location for plants that need less sun and summer heat than the rest of the yard provides. And I have some other beds the same distance from a board fence that are doing spectacularly (the tomatoes are 7 feet tall right now, and still growing), so I don't think there's a problem with air circulation. I'm not going to move the beds I've already dug unless the roots of the plants would come into contact with a pesticide.
