Good design concerns itself with the customer’s Sustainability has many different meanings. It can be property and any surrounding property so that they defined as an approach to landscaping that function in unison. emphasizes plant health and longevity. Sustainability does not mean the elimination of inputs into the Landscape design requires creativity, knowledge of landscape such as fertilizers, pesticides, labor and design principles, drawing skills, and the ability to financial investment. It includes the creation of work with people. It requires a knowledge of outdoor spaces that attempt to utilize fewer inputs, environmental conditions such as soil, wind, sun, and that are environmentally friendly, and that are self- precipitation, as well as knowledge of landscape perpetuating over a period of time. This requires a materials such as wood, stone, brick, concrete, and harmonious relationship among all components in the plants. In terms of plant material, the landscape landscape. Such a landscape will improve the architect and designer must be familiar with the environment by conserving resources, reducing cultural requirements of specific plants, their chemical applications, as well as labor inputs, which aesthetic characteristics, and how these make it less expensive to implement and maintain. characteristics can be used to fulfill a particular design function. Landscape design differs from Creating a sustainable landscape requires that the other art forms because the completed results design process should be considered first. Plant constantly change with each season and with yearly selection, implementation, and maintenance build on plant growth. the design process, each having sustainability as a major consideration. By utilizing these concepts, Landscape architects, professionally trained homeowners, business owners, and related industry landscape designers, or those who have many years personnel will be able to create outdoor spaces that of on-the-job experience are qualified to develop are functional, maintainable, environmentally landscape designs. Architects and designers must sound, cost effective and aesthetically or visually listen carefully and ask detailed questions to insure pleasing.

However, a The Base Plan landscape should be functional from both the user The Base Plan is developed from the information and the maintenance standpoint. A maintainable collected about the site by the landscape designer or landscape lowers labor costs and makes maintenance landscape architect. Base Plan information is the operations easier. It also reduces the need for starting point in the development of landscape fertilizers, pesticides, equipment, water and other design. Information is obtained from many places inputs.
