Continue to water your new succulent as you would all of your other plants until next spring or summer when it becomes time to propagate some more pups. It needs to sit in the water for at least 24 hours, though a little more would be better. Two weeks is required to water a newly planted barrel. To water from the bottom, place the plant on a tray or in a shallow dish with water. Allow it to sit for about 2 or 3 inches. Use as a side dish or add to salsa and tacos.
