Subirrigation

Subirrigation is like a giant underground lake. It's a special kind of irrigation that keeps plants watered without using sprinklers or other watering systems. Instead, water is put in an underground tank, and then allowed to slowly come up through the soil. The water comes up through the roots of the plants, making sure that they get the water they need to grow. The water is also re-used, so it's a good way to conserve water.
