Rinse an empty wine bottle, (or other glass bottle with a narrow neck) and fill with water. Standing next to your planter, quickly turn over the bottle and push the neck down into the soil near the center of the planter. Make sure the neck is at least several inches underground. The water in the bottle will seep into the soil over several days, keeping the soil evenly moist.
To make this waterer drip even slower, fill bottle 1/4-1/3 of the way with fine gravel before filling with water. Place cheesecloth or cotton scraps over bottle mouth and secure with twine. Insert deeply into soil.
