The invention relates to the field of garden beautifying equipment, in particular to a garden flowerpot placement device. The device comprises a conveying belt for conveying flowerpots needing to be placed, flowerpot clamp pushing mechanisms are arranged on the two sides of the conveying belt, and flowerpot clamps are arranged in the flowerpot clamp pushing mechanisms. Each flowerpot clamp comprises an adsorption clamp body and a magnetic clamp body which are in an arch shape, wherein a through hole allowing a flowerpot to be placed therein is formed in the middle after the two clamp bodies are spliced, on the side face where the adsorption clamp body and the magnetic clamp body are attached to each other, the magnetic clamp body is provided with a first magnet, and the adsorption clamp body is provided with a concave hole corresponding to the first magnet. The garden flowerpot placement device has the advantages that the design is reasonable, the structure is simple, the clamp bodies are automatically clamped for the flowerpots through the pushing mechanisms, the clamp bodies are divided into two parts, and when the two parts make contact with each other, hooks can be automatically triggered to keep integrity of the clamp bodies; the flowerpots are mutually connected through magnetic adsorption, and the flowerpots can be placed at any angle.
