Each block in turn has rows laid out, that are 15′ apart. About 12 rows per block are being planned. Now here is another detail. Starting from the road, the tree rows are designated 6-5-4-3-2-1-1-2-3-4-5-6. Trees to be planted are sorted according to their eventual heights. The tallest will planted in rows 1 in the centre of the block. Rows2 will have somewhat shorter plants and so on, until in Rows6 on either side of a block and where cottages are located, the species will be bushes or shorter plants.
The reason for this approach is again to assure solar equity for all plants and to prevent entire acreages shut out to sunlight. Looking from a east-west road, one would see a rising wall of green and viewing from east or west one sees a semicircular profile. To summarise, the trees crowns are oriented to capture the sun while, contour trenches will enable their roots to be kept moist.
Finally a caveat. Insofar as I know this reasoning has not been reduced to practice in the same way as I intend to. Logic tells me it will work well. I will attempt this in two acres this year and observe the effect. I am confident nature will make this caveat redundant.
