Marshall Grain Co.

Marshall Grain Co. is an organic garden center and landscape company that sells organic fertilizers, composts, mulches, tools and plants, including Texas natives, trees, shrubs, herbs and vegetables. Its landscape division handles design and installation, hardscaping, drainage and erosion control, lighting, water features and ongoing organic lawn maintenance. The business traces its roots to a feed and grain store in Fort Worth in the early 1900s and moved to its current Colleyville location in 2024.

The garden center has a retail shop, a large greenhouse and an outdoor nursery, and it stocks wild bird food and feeders along with the plants. Store hours are Monday through Saturday 9 AM to 5 PM and Sunday 10 AM to 3 PM, and dogs on leashes are welcome inside. The landscape crews work across much of the Dallas-Fort Worth area, including Grapevine, Southlake, Arlington, Keller and Flower Mound.
