A method of digging and transporting trees comprising the steps of: cutting the earth and roots surrounding a tree by a series of spades which move radially downward and inward from an excavating machine in a cone-shape; providing a trailer-mounted receptacle having an open bottom and a cone-shape substantially identical to the root ball lifting the root ball and tree by the excavating machine and depositing said ball and tree in said trailer-mounted receptacle for transport to the site of relocation; transporting said tree to the site of relocation; reengaging the ball and tree by extending the spades of the excavating machine between the ball and the receptacle until said spades project through the open bottom of the receptacle; lifting the ball and tree out of the receptacle with the excavating machine; and depositing the ball and tree in a ground cavity previously dug.
