Terracotta Bottle Olla Irrigation Pots | Set of 2 Large 1200ml

A large terracotta bottle olla for deep, water-wise irrigation — set of two

This set of two large bottle ollas brings one of the oldest irrigation methods in the world to multiple garden beds or pots at once. Buried in the soil and filled with water, the porous terracotta walls slowly release moisture directly into the root zone where plants need it most. Less evaporation, less surface watering and stronger, deeper root systems as a result. A quiet, effective solution for the Australian garden.

How ollas work

Bury each olla up to its narrow neck, fill with water and replace the lid. The unglazed terracotta clay releases water slowly and steadily into the surrounding soil through capillary action, drawn by the roots of nearby plants. The soil directly around each olla stays consistently moist while the surface remains dry. This eliminates the cycle of wet and dry that stresses plants between waterings.

In the Australian native garden, where deep, infrequent watering is the ideal and overhead watering can cause problems with disease-susceptible species, ollas offer a particularly well-suited alternative. Plants establish faster and develop more extensive root systems when moisture is delivered at depth rather than at the surface.

Low-maintenance watering for multiple plants

Once buried and filled, each olla works without intervention making a set of two large ollas ideal for covering a substantial vegetable bed, a pair of larger pots or two well-established garden plants at once. A reliable solution across busy weeks, holidays and the long dry stretches of the Australian summer — no timers, no tubing and no daily checking required. Every piece is made from natural red terracotta clay fired at high temperatures for strength and durability and may show the natural variations in tone and texture that come with terracotta.
