A plant watering assembly for retaining water around a plant includes a canister that is positionable around a plant. The canister is comprised of a fluid impermeable material thereby facilitating a fluid to be poured therein. Thus, the canister retains the fluid around the plant for nourishing the plant. The canister has a plurality of spikes thereon and each of the spikes pierces ground when the canister is positioned around the plant. In this way the spikes inhibit the canister from being displaced.
