The invention discloses a cherry tree steep slope planting structure. The cherry tree steep slope planting structure comprises planting holes formed in a steep slope, wherein the outer sides of the lower edges of the planting holes are provided with a timber pile row, slope surfaces of the upper portion of the planting holes are fixedly provided with geo-cells, the geo-cells are internally provided with herbaceous plants, each planting hole is filled with a grit layer, a base fertilizer layer, an isolating soil layer and a planting soil layer in sequence from the bottom, and cherry trees are planted in the planting soil layers of the planting holes. The cherry tree steep slope planting structure can increase the survival rate of the cheery trees planted in the steep slope, reduce the lodging rate in the later maintenance process, and prevent the soil erosion and landslide which may occur on the steep slope.
