In addition to the one-year guarantee, we agree to extend this guarantee for as long as we are retained to provide significant services on your yard. Significant services means that we will be your landscapers for most of your landscaping needs such as mowing, trimming bushes, mulching, planting flowers, etc. So basically, for as long as we are retained as your landscapers, we agree to fix or replace any of the items under guarantee provided that they are receiving adequate water and you allow us to treat them as needed for insects or disease. They will be replaced by similar size and shape items as we installed, or you can receive a credit of the original price towards a larger plant.
