Garden planting method for waste soil

The invention relates to a garden planting method for waste soil, wherein the waste soil is engineering waste soil. The steps for turning the engineering waste soil into the soil needed by garden planting are as follows: (1), a soil solidifying agent is added in the engineering waste soil and stirred and mixed; (2), the engineering waste soil stands for 2-3 days under the processing plant environment that the room temperature reaches 20-25 DEG C, pore water in the engineering waste soil generates hydration reaction with the added soil solidifying agent, and free water in pores of the engineering waste soil is turned into bond water; and (3), the obtained engineering waste soil with bond water is processed through a solidification processor to obtain nutrient soil for garden planting. The method has the advantages as follows: tree planting holes needed by garden trees are dug out on the nutrient soil for garden planting, trees are planted in the tree planting holes, and fertilizer is applied; by the added soil
