Gardeners who travel will love these absorbent clay pots from Egypt. Modeled after the Olla, an ancient ceramic pot prevalent throughout North Africa, the small vessels are designed to water plants for weeks at a time–using nothing but gravity. Clayola founder Rami Halim says 20 liters (5 gallons) of water can sustain six to eight plants for up to a month.
The Clayola pots, connected via a pipe to a water source placed at a slightly higher elevation, are pushed into the soil until the colorful tops are flush with the surface. A small siphoning pump gets the water flow going and then gravity takes over from there. The porous clay vessel acts like a sponge that slowly releases a small amount of water into the soil – just when it starts to become thirsty.
“As water evaporates from a plant’s leaves, it draws water from the soil and as the soil dries up water is drawn from the Clayola to the soil,” Rami said. “In effect the plant extracts the water it needs from each clay pot.”
“After a while,” he added, “a plant’s root system will find the source of water and literally hug the Clayola, allowing for maximum water use.”

Rami says Clayolas are ideal for travelers. Unlike those of us who tend to either starve or drown plants, this system guarantees “each plant gets the exact amount of water it needs at no risk of over or under irrigation.” And it is said to be 80 percent more efficient than conventional irrigation techniques.
Just 3 x 5 inches, the Crayola has a tapered shape that serves multiple functions. Not only does it maximize watering surface at the top, but it also makes it easier to penetrate the surface of the soil. The colorful glazed tops prevent evaporation and enhance the design’s playful aesthetic.
There are two reasons Clayola favors employing skilled artisans in Cairo to make their products, according to Rami. “The handmade imperfections are absolutely beautiful,” he said, “and this old world craft is efficient, elegant and produces a surprisingly durable product.”
