The Annual Calculator offered by www.LandscapeCalculator.com is a unique estimating tool for both small and large landscape projects. The Annual Calculator allows you to estimate how many annuals (flowers) are required for a given area, or landscape bed, based upon plant spacing. The number of trees in the landscape bed is also taken into consideration since trees and their root balls take up space in a landscape bed. Also, see “how it works” built by landscape experts, and compare our calculator to other annual calculators. Landscape professionals and landscape architects across the country use LandscapeCalculator.com on a daily basis to properly estimate the number of annuals (flowers) a new or existing landscape bed will require based upon the square footage of the landscape bed and the specified plant spacing. Calculating the proper annual (flower) quantity is important and may save labor and valuable space on the truck.
