C. Johnson Landscape Co. Inc. Started in 1956 in Cranston, RI by Milburn T. “Gramps” Johnson as a residential lawn maintenance company. As the company continued in the hands of his son Charles “Chuck” Johnson, he added landscape construction and design. Chuck ran the company while Milburn purchased a florist shop – Plainfield Florist. Later after selling the florist shop Milburn rejoined the company full time. Chuck’s son Chad graduated from URI in horticulture and entered into the business full time in 1996. Chad added Tree/shrub/lawn health programs as well as adding landscape lighting design. Although we are family company of approximately 10 employees we have the ability to consult, design, and/or install in almost any phase of your Landscape needs.
