Then you keep it full of water as a means of passive irrigation.

You can also purchase commercially-produced ollas, and to my surprise they're even being carried by big-box hardware stores now, but they're far cheaper to make than buy. You can make one for about one third the cost of retail.

If you have small children, making ollas can be a good family project, as many kids love to get involved with this kind of thing. Now that it's summer and school is out, a few of the neighborhood kids have become fond of asking me, "Do you have any work that I could help with today?" (seriously!) because they see me working on my landscaping frequently and they like to get involved. One of these days I'm going to remember to stop by the hardware store and pick up another batch of clay pots so that we can collaborate on making some more of these.
