I saw an article lately, about planting trees for shelter. I would suggest that, if the parties would set the trees at regular distances for orchard planting, in any State of the United States, and then let the trees branch low, where hot suns prevail, I would advocate not higher than one foot. I think it is the best and only shelter needed to protect from sun or cold. There is another advantage of low trees in early bearing, and on trees properly trained the fruit will be as fine and high flavored as trees trained high.
