Watering Woes? Ollas To the Rescue!

Every gardener knows that a vital aspect of a successful garden is water. Your plants need water to grow and produce. But if you live in areas prone to drought, have very warm summers, or need to be away, keeping your plants well-watered can be a challenge. This is where the olla clay pot comes in!

What Is An Olla?

It’s got a funny little name, but it does serious work. An olla (which literally means “pot”) is a round, unglazed terra cotta clay pot with a long neck that you fill with water and bury next to your plants. It irrigates in the ground.

How Do Ollas Work?

The concept is simple: ollas keep your plants watered through a process called soil moisture tension. When the soil around the olla is dry, the water is pulled out through the pot’s “pores” and provides it to thirsty plants. If the soil is moist, the water stays in the pot. The roots of your plants eventually grow toward and around it, allowing for even and consistent watering.

This is not a gravity feed system, like holes in a milk jug where the water continues to flow until empty, but rather a tension concept, where the olla is wet, and the soil is dry. The best part: it won’t over or underwater your plants—it’s as if the olla knows what the plants need! This supply-and-demand system proves to be very Earth-friendly by saving between 50% to 70% in water use.

Olla History

Clay pot irrigation can be traced back thousands of years. It was designed during a time when watering meant hauling water in vessels. Anthropologists have been digging up unglazed clay pots from long-forgotten ancient garden sites, from China to South America. Those unglazed pots solved a lot of civilization’s water issues: they were inexpensive and could go days without filling. Nothing has changed: clay pot irrigation still does all that.

Which Olla Do I Choose?

Ollas come in a variety of sizes. Choose one with a lid to decrease evaporation and one that fits the space you’re watering. The larger the olla, the less often you have to fill it, and the larger space it will water. For example, a 2.9-gallon/11-liter pot will water a three-plus-foot diameter circle for 3 to 7 days. That works well with a 4 x 4 garden or raised bed. Smaller pots will water less and are better suited for small-space gardens.  If you’re heading out on a trip or vacation, ollas are like that helpful friend who cares for your plants while you’re gone. Simply water your plants well and fill your olla. A week later, you will return to happy plants.

Benefits of the Olla – A Snapshot:

  • They conserve water. They save between 50%-70% in water use.
  • They’re a time saver. No hauling water jugs, positioning hoses.
  • They’re inexpensive.
  • They produce healthier plants. Because soil moisture tension creates an environment where roots get slow, even watering around the clock, the root base grows larger, producing a healthier plant.
  • There are many sizes to choose from. They can be used in raised beds and container gardens.
  • Fertilizing is easier. Add a liquid fertilizer directly to the clay pot—it uses 1/3 less fertilizer, another money saver!
  • They’re low-tech. They’re easy to use—anyone can do it! And no electricity needed.
  • They’re a vacationer’s friend. Perfect when planning trips, during a busy work week, or when rain is sparse—larger ollas can go 3 to 7 days without filling.
  • They’re Earth-friendly. Ollas are organic, made from clay. They leave no plastic residue in the earth for the next generation to worry about. Ollas are great neighbors to the environment and earthworms alike!

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
