An elongate cultivating tool adapted to be supported at each end so as to be able in use to rotate about a longitudinal axis. The cultivating tool comprises an elongate cylindrical support (1) which may be a helical coil spring, a plurality of cultivating elements (2) on a peripheral cylindrical surface of the cylindrical support, each cultivating element linking up with four other like cultivating elements on the peripheral cylindrical surface and one and preferably two tines (3) extending from each cultivating element. There may be two banks of cultivating elements on the tool to give a greater number of tines on the tool. The axle (6) to support the cylindrical support for rotation may be telescopic to provide tension to maintain the position of the cultivating elements. The cultivating elements are formed from metal rod and in one form comprise a U-shaped body with each leg of the U-shaped body including a bend out of the plane of the body with each portion beyond the bend comprising a tine. In another form the elements comprise a circular loop portion, two tangential legs extending from the loop portion and crossing each other and each leg including a bend out of the plane of the loop portion beyond the crossing with each portion of the leg beyond the bend comprising the tine.
