When planning your water-wise gardening, you'll find it very helpful to become well acquainted with the growing conditions in your yard as well as your area. Even the smallest property will have what is termed "micro-climates" created by the house, outbuildings, slopes, low spots, and existing shade trees. By being familiar with your property and its different growing conditions, you can make a more informed, successful choice for the plants you use in the various parts of your landscape
A microclimate is created when a building, large tree or the topography of your property changes the amount of sunlight, water and wind that the spot receives as compared to an open area with nothing but open sky above.
