In my own garden there are some spots where I cannot put the kinds of plants that are hurt by winds. Practically every garden is unique in this respect. One of the functions of both low and high evergreens is to help buffer the wind for other plants. Generally speaking, temperature is a bit higher in areas where a high proportion of the space is used for streets and sidewalks. The temperature is generally higher on the sunny side of wallsfacing south and southwest-and near unshaded walks.
Many people make gardens in areas which already have plantings of trees and hedges.
Partly for temperature and for other reasons, some of these old plantings may need to be removed. Generally, the local temperature near a south-facing wall is warmer than the surrounding area. Many gardeners have south-facing stonewalls or brickwalls on which they train fruit trees or other plants to grow flat against the wall. That is, all of the branches that grow out from the wall are pruned away. A great many gardens in northwestern Europe grow peaches and other fruits this way.
