|Ollas from El Traspatio|
The newest technology is drip irrigation; the oldest is called an 'olla' – pronounces OYE-ya. Variations of ollas are found in many ancient cultures and there is a move to put them back into gardens today.
It is most important to have water at the roots of plants – spraying water into the air to fall on the soil, is not very efficient. A lot of that water can be blown away from your plants (on to the neighbors!) and a lot evaporates off into the air. But there are other ways to to water that are better. All these other ways involve putting the water close to the root zone. The two ways to do this include some of the newest technology and some of the oldest technology.
