Up here because we avg. mid 70's to low 80's in summer we have to take advantage of any warm microclimate we can get. At my house I have a south wall with vurtually no windows. There is a long but shallow planting bed in between the wall/foundation and a sidwalk. The bed is located elevated from the common sidewalk and street about 7 feet. The foundation of the house is only exposed about six inches so I know that doesn't come into play. So my question is does wood siding (Hardy Plank/Board)create a decent microcimate? BTW the siding is not white but light green. I know sometime color matters.
