A planting apparatus of nursery tree 2 comprises an auger 11 for excavating a planting hole on a ground, a guide member 12 having a hollow tube shape for putting a nursery tree into the excavated hole, a blade member 13 for leveling, covering and pressing soil around the nursery tree, sliders 15, 16 and 17 as a lifting means for moving them up and down in a same vertical axis line direction, and motors 18 and 19 as a rotation means for rotating the auger and the blade, wherein the auger, the guide member and the blade member form the nested structure of the three-layert which are centered upon the auger, and the auger and the blade member are rotation members rotating on the same vertical axis line. By such a constitution, desired planting hole can easily be excavated, and the ground around the excavated hole and a root clump of the nursery tree can be leveled, covered and pressed by the blade member 13 without forming a gap while holding the nursery tree by the guide member 12 not to be inclined.
