If there are a lot of tall trees close together in a space, do you think there will be a lot of grass on the ground? Write to explain your answer.
Answers
Answer:
Trees properly selected and placed can add more in livability and value to the home than any other single landscape feature. They grow continually and are ever-changing. You will never tire of looking at them.
Trees around homes provide beauty, but their more practical function is to fulfill needs and solve problems in the home landscape.
Trees solve landscape problems by providing framing and background. Trees also improve the appearances of our homes. They can help to absorb noise, freshen the atmosphere, serve as windbreaks, provide privacy, protect, shade, shelter and divide grounds into several use areas.
Home landscapes are not, and should not be, identical. Therefore, the same kind of tree cannot be used for the same purpose on every lot. To get the most from your trees, follow these guidelines:
- Determine where trees will serve the greatest benefit.
- Select trees that fit locations and fulfill needs best.
- Properly plant, care for and maintain trees.
Functions of trees
Shade
Trees are most frequently planted for shade. The most important shade tree on home grounds is usually located near the southwest corner of the house. If placed properly, it will shade the house during the latter part of the afternoon in summer. Trees provide better shade than artificial structures. Air passing through the branches is cooled by transpiration from the leaves.
Distance
Depending on the mature size of the tree, the distance it is set from the house will control the amount of shade given in a certain area. A tree 50 feet high with a 30-foot spread will cast a shadow equal to the tree height at 3 to 4 p.m. in midsummer. But in winter, the shadow at the same time of day will be 120 feet long. To get the most useful shade on the house at a practical distance, place the tree 15 to 20 feet from the house. Small trees may be planted closer than 15 feet, but large trees should be planted 20 feet or more away from the house.
Location
If the house faces south, or southeast, maximum shade on the front will come from a tree that is placed to the southwest, or left front. If the house faces southwest, a tree for maximum shade would have to be placed centrally and south of the house (see Figure 1). Make a diagram of your house and sketch trees with their shade patterns to determine the best locations. Do not plant large evergreens directly south of a building, as doing so greatly reduces solar gain in winter.
