How to Make DIY Ollas (Olla Pot)

Ollas, ancient clay pots used for irrigation, offer a sustainable and efficient way to water plants by delivering moisture directly to the roots. Making your own ollas not only connects you to an age-old practice but also allows you to customize them to fit your garden’s needs.

How to Make DIY Ollas (Olla Pot)

In this guide, we’ll explore the art of crafting DIY ollas, from selecting materials to installation tips, empowering you to create a simple yet effective solution for water conservation and plant health in your garden.

Materials Needed

To embark on your DIY olla-making journey, gather the following materials:

  • Clay: Choose a high-quality, natural clay suitable for pottery. This can often be found at local pottery supply stores or online.
  • Sand: Fine sand will be mixed with the clay to help prevent cracking during the drying and firing process.
  • Water: Essential for mixing the clay and sand to the right consistency for molding.
  • Tools: Gather basic pottery tools such as a rolling pin, carving tools, and a cutting wire to shape and sculpt the clay.
  • Optional Additives: Some crafters choose to incorporate additives like grog (fired clay particles) or straw into the clay mixture for added strength and texture.
  • Kiln or Firing Access: If you plan to fire your ollas to harden them, access to a kiln or a pottery studio that offers firing services will be necessary. Alternatively, there are air-dry clay options available that don’t require firing.
  • Glaze (Optional): If desired, glaze can be applied to the ollas for decorative purposes or to further protect the clay surface.

By gathering these materials, you’ll be equipped to start crafting your ollas and bring water-saving benefits to your garden.

Step-by-Step Guide to Making Ollas

Shaping the Clay:

  • Begin by preparing your clay mixture. Mix the clay with sand and water until it reaches a workable consistency, similar to that of pottery clay.
  • Use a rolling pin to flatten the clay to a consistent thickness, typically around 1/4 to 1/2 inch thick.
  • Cut out circular shapes from the clay using a template or any round object of the desired size. These will form the base of your ollas.

Creating the Olla’s Body:

  • Take one of the circular clay pieces and begin to mold it into a shallow bowl shape, using your hands to gently press and shape the clay.
  • Once you’ve formed the bowl shape, gradually build up the sides to create the desired depth of the olla, keeping the walls uniform in thickness.

Crafting the Neck and Opening:

  • To create the neck of the olla, roll a small piece of clay into a cylinder shape and attach it to the center of the bowl’s top edge. This will serve as the water reservoir.
  • Using your fingers or pottery tools, shape the clay around the neck to form a smooth transition from the bowl to the neck.
  • Create a small opening at the top of the neck, allowing water to be poured into the olla.

Drying and Firing Process:

  • Allow the newly formed ollas to air dry slowly and evenly to prevent cracking. This process may take several days to a week, depending on the thickness of the clay and the humidity of the environment.
  • Once the ollas are completely dry, they can be fired in a kiln to harden the clay and make them durable for outdoor use. Follow the specific firing instructions for the type of clay you’re using, typically involving gradual heating to high temperatures.
  • After firing, allow the ollas to cool completely before handling them. Once cooled, they are ready to be installed in your garden for efficient irrigation.
  • Following these steps will guide you through the process of creating your own ollas, providing a sustainable and effective method for watering your plants while adding a touch of handmade beauty to your garden.

Using and Installing Ollas in Your Garden

Choosing Placement:

Select suitable locations in your garden where plants require consistent watering. Consider factors such as plant type, sun exposure, and spacing when determining placement for your ollas.

Digging Holes:

Dig holes in the soil where you plan to install the ollas. The depth of the holes should accommodate the height of the ollas, allowing the necks to remain above ground for easy access.

Installing Ollas:

Place the ollas upright in the holes, ensuring they are stable and level. The necks of the ollas should protrude slightly above the soil surface.
Backfill the soil around the ollas, gently pressing it down to secure them in place.

Filling Ollas:

Once installed, fill the ollas with water through the openings at the top of the necks. Allow the water to slowly seep into the surrounding soil, providing moisture directly to the roots of nearby plants.

Monitoring and Refilling:

Check the water levels in the ollas regularly, especially during hot or dry periods, and refill them as needed to ensure continuous hydration for your plants.

Adjust the frequency of refilling based on factors such as weather conditions, plant growth, and soil moisture levels.

Observing Plant Health:

Monitor the health and growth of your plants to gauge the effectiveness of olla irrigation. Look for signs of improved hydration, such as lush foliage and healthy root development.


  • Periodically inspect the ollas for any damage or clogging that may affect their functionality. Clean the openings and necks if debris accumulates, and repair any cracks or leaks as necessary.
  • During the winter months or when not in use, consider removing the ollas from the ground and storing them indoors to protect them from freezing temperatures and potential damage.
  • By following these steps, you can effectively utilize ollas in your garden to provide efficient and targeted watering for your plants, promoting healthy growth and conserving water resources in the process.

Maintenance and Care Tips for Ollas

Regular Inspection:

Periodically inspect your ollas for any signs of damage, such as cracks or leaks, which can compromise their effectiveness. Check the openings and necks for debris buildup that may obstruct water flow.


Clean the openings and necks of the ollas regularly to prevent clogging. Use a small brush or cloth to remove any dirt, sediment, or mineral deposits that may accumulate over time.

Repairing Damage:

Repair any cracks or leaks in the ollas promptly to maintain their functionality. Use a suitable clay repair kit or clay mixture to patch small cracks, ensuring a watertight seal.

Winter Care:

During the winter months, consider removing the ollas from the ground and storing them indoors to protect them from freezing temperatures. Alternatively, empty the ollas and cover them with a protective layer of mulch or insulating material.

Adjusting Water Levels:

Monitor the water levels in the ollas regularly, especially during hot or dry periods, and adjust the frequency of refilling based on weather conditions and plant needs.

Seasonal Maintenance:

Before the start of each growing season, thoroughly clean and inspect the ollas to ensure they are in good condition for use. Replace any damaged or deteriorated ollas as needed.

Protecting Against Pests:

Take measures to protect the ollas from pests such as rodents or insects, which may be attracted to the water inside. Consider covering the openings with mesh or placing protective barriers around the ollas to deter pests.

Long-Term Storage:

If you plan to store the ollas for an extended period, ensure they are completely dry and free of moisture to prevent mold or mildew growth. Store them in a cool, dry place away from direct sunlight.

By following these maintenance and care tips, you can prolong the lifespan of your ollas and ensure they continue to provide efficient irrigation for your garden, season after season.

Final Thoughts
