Landscape contractors generally provide two main types of services: landscape maintenance and construction. As a rough rule, if your current project requires maintenance such as for lawn and trees, many landscapers do provide services for these. Although this work may be performed by tree and lawn services in and of themselves.
Landscape construction on the other hand, normally deals with grading, irrigation, heavy planting and structures situated among the landscape. Knowing the basic difference can help you in your search. [ closely related:Architects for Landscape/Design]
