On the topic of home shades, most people think of canopies, awnings and pergolas. A less conventional way to provide home shade but perhaps is more rewarding is to plant a tree. If planted in the right climate and watered correctly, some trees will grow up to 15 ft in one year.
The Dept of Agriculture of the American government has divided the country into more than 10 Hardiness Zones that indicate the best types of trees that grow in each zone. The zones are divided according to amount of precipitation received every year, length of seasons, and temperatures. Each zone has an optimal set of trees.
The poplar tree serves well as an example of a tree that belongs to the Hardiness Zones 3 through 9. These zones cover almost all latitudes of the US from north to south. Poplars grow in the wild but have been domesticated to grow in front and back yards of homes.
If it takes root in the most conducive zones, these poplars exhibit growth rates of 2 to 3 meters every 12 months. At its full height, it is up to 18 to 23 meters. Of course, considerable yard work should be done in that time to ensure the tree does not grow to dangerous heights. Poplars will grow as far south as Texas and Florida.
The artificial counterpart to trees is the canopy. Canopies are tent-like shades. Two aspects make up the tent-like structure of a canopy: a metal scaffolding and a piece of canopy fabric that is covers it. The shading fabric almost always covers the roofing to shield against direct sunlight but the walls are more variable, depending on whether one is more concerned with privacy or better circulation in the canopy.
Most exterior shading is designed to stop nearly all light. Pergolas were made with another purpose. Rather than supporting fabric material, the posts of a pergola hold up wooden slats that stop only a fraction of the light. A related outdoor shade to the pergola is the garden arbor. The arbor is smaller in size, much simpler in construction, but cannot shade many people at once. In recent times it’s largely a decorative element of the garden.
