A binding machine for gardening includes a main handle capable of drawing out a tape from a front end portion thereof, a clincher arm rotatably attached to the main handle, a tape gripping device attached to a front end portion of the clincher arm and is capable of gripping an end portion of the tape drawn out from the front end portion of the main handle, and a bonding unit configured to bond end portions of an overlapped tape. In a case where the clincher arm completely closed with respect to the main handle is viewed from the side, when a bonding direction of the bonding unit is defined as a longitudinal direction and a direction orthogonal to the longitudinal direction is defined as a transverse direction, the tape gripping device is configured such that a width in the longitudinal direction thereof is 1.5 times or less than a width in the transverse direction thereof
