Abstract: Disclosed herein is a mixing device suitably fashioned for assuring a substantially uniform mix of seeds and planting medium such as peatmoss. The apparatus is defined by a framework which supports a drum capable of rotation not only about it's elongate axis, but also rotation about an axis orthogonal thereto. A door is provided for ingress of material, a spout for egress therefrom, and mixing blades are disposed within the drum's interior to assure the proper mix.
