In order for landscape shading to work well a lot of planning needs to go into the landscapes design. Trees need to be planted in just the right location so that they shade the home at the time it is needed most. You will also need to consider the type of trees to plant. Remember, the denser the tree, the more shade your home will get. If you want shade in the summer but would like the suns heat to warm the home during cooler months it is best to choose deciduous trees which will lose their leaves in winter, allowing for the sun to reach the home.
There are a few points to think about with landscape shading, however. Trees will take some time to reach their full height so its unlikely you will see immediate energy saving results. If you are looking for more rapid results then vines are a good choice. Try growing them to wrap around a fence or trellis in the area you require shade. You can also plant shrubs which are ideal for shading pathways or driveways.
To summarize, landscape shading is an environmentally friendly way of helping to cool your home during the hot months.
