Grower's structure for shade tree of the invention includes: a upper space (a), from collected overhead rainwater and temporarily stores collected rainwater; One undercurrent space (B) is disposed in a lower part of upper space to store collected rainwater, and such rainwater can slowly penetrate into soil; One soil space (C), is formed towards the inside of upper space and undercurrent space, filled with soil for planting. Upper space (a) cleans collected rainwater filled with filter medium. It is adaptable to the multiduty filter (151 of one or more of climate change, 152) it is configured to provide rainwater store in soil space (C), can slowly be supplied with the root of a tree planting in the rainwater store of undercurrent space (B) in this way and pass through connect undercurrent space (B) with soil space (C) for a long time. Grower's structure for shade tree further comprises that an iron grate (200) can cover upper space (a) after one tree is planted in soil space (C).
