Two effective choices for supporting these vines include a trellis and a lattice support. How well a tree suits your need for shade depends on many factors. Consider shrubs if neither trees nor vines are right for you. Shrubs can provide shade on the lower part of the wall not shaded by the roof overhang. As with all landscaping materials, provide some space between the plants and your home to prevent moisture pockets.
Plants placed too close to the home can trap moisture, creating mildew problems.
Allow enough room for air to circulate behind the foliage. Shading with landscape materials does keep the sun from warming your home in the winter and that can increase heating costs. In central and south Florida the change in utility costs is generally very small. This allows for shading in the summer and sun warming in the winter. In the summer, Floridians often find it difficult to stay comfortable without air conditioning.
