ABSTRACT:
A leaf disposal bag is formed from a large diameter thin plastic circular sheet. A drawstring is woven through a plurality of evenly spaced apertures provided around a peripheral edge of the circular sheet. A pair of radially extending tabs are formed at diametrically opposed locations on the sheet and each receive a ground insertion spike for retaining the circular sheet in a flat open condition on the surface of the ground. In use, leaves to be disposed are piled upon the upper surface of the circular sheet. Upon collection of a sufficiently large volume of leaves, the ground insertion spikes are withdrawn from the ground and the drawstring is tightened to close the circular sheet into a closed bag. The ground insertion spikes may be formed as a separable enlarged head portion and a sharpened shank portion having a mating frusto conical plug and socket connection.
