Ollas are a traditional way to save water and simplify your houseplant care routine. Just “plant” the olla into the soil with the cork end exposed and fill it with water; moisture will seep slowly through the terracotta. Eventually, your plants’ roots will attach themselves to the olla and draw out the water they need. Ollas are a traditional way to save water and simplify your houseplant care routine.
