I claim the ornamental design for a decorative cover for a multi-leg hanging basket, as shown.
FIG. 1 is an isometric radial view showing the decorative cover associated with a multi-leg hanging basket. The broken lines on the inside of the basket portion are for illustrative purposes only and form no part of the claimed design.

FIG. 4 is an isometric view of a basket portion of a hanging basket without the basket hanging arms, where the basket portion is covered by the decorative cover of FIG. 1. The broken lines on the inside of the basket portion are for illustrative purposes only and form no part of the claimed design.
