A hollow hose has a series of preformed triangular units or sections in connected sequence, with one leg of each unit adapted to engage the ground when the hose is stretched to correspond to the length of the area to be sprinkled. The upwardly extending and downwardly extending legs of each unit or section have outwardly disposed holes, through which the liquid for sprinkling is discharged. For a shorter hose, the holes may be of the same diameter, but for longer hoses smaller holes at the inlet end and larger holes at the opposite end may be used, with intermediate size holes between for still longer hoses. Special stakes for holding the bottom legs at opposite ends to the ground may include an arcuate notch for engaging the corresponding hose portion and a stem alongside the notch for penetrating the ground. A transverse flange, opposite the stem, is used in driving the stake and each flange has an aperture for receiving the stem of the opposite stake, when clamping the bottom legs of the units between the stakes for storage purposes. With the hose sections in longitudinal alignment and compressed together, a first stake may be placed longitudinally on the inside of the bottom legs and the stem of the second stake slipped into a round hole in the flange of the first stake as the second stake is placed against the underside of the bottom legs. Then, the stem of the first stake is slipped into a transverse slot in the flange of the second stake, which slot has an offset at its inner end to prevent the stem of the first stake from slipping out. The position of the apertures should be such that the bottom legs of the hose sections will be clamped or compressed between the stakes.
