Every garden has a number of different microclimates, and these have an effect on not only the temperature but also the amount of rainfall and wind strength. Even within a small garden, there can be large differences in conditions. If you have been digging or weeding your garden for a while, you will probably have discovered hot, dry corners and cold, draughty spaces. Understanding the microclimates in your garden really gives you a head start. Most gardeners want light and shade, dry and damp, sheltered and exposed areas in which to grow different plants and create contrasting spaces.
