Four teardrop ollas of 320 ml, for pots, planters and raised beds

The pack of 4 terracotta ollas for planting allows you to water pots, planters and raised beds from below the soil. Each olla holds 320 ml and is planted point down in loosened compost. Water seeps through the clay as the soil dries. One olla is enough for a 15 to 20 cm pot, and 3 or 4 for a planter.

This pack contains 4 drop-shaped ollas, each holding 320 ml, which are planted point-down into the compost of a pot, planter, or raised bed. You fill them from the top, and water seeps into the soil through the terracotta at the rate it dries out.

💧 Four 320 ml reservoirs

Each olla measures 14.2 cm tall by 8.2 cm wide and weighs approximately 210 g empty. Its teardrop shape ends in a point that makes it easy to insert into loosened compost, while the opening sits at the top, flush with the soil surface, for filling. With 4 units, you can equip 4 separate pots, or space them along a planter box, with each reservoir filled independently of the others.

The moistened zone around an olla is roughly twice its diameter, about fifteen centimetres for this 8.2 cm model. A single olla is therefore suited to a pot approximately 15 to 20 cm in diameter, placed close to the roots, whereas a deep raised bed is better served by a burial jar of 1 to 6 litres. In a 60 cm planter, place 3 or 4 of them, spaced around fifteen centimetres apart, so that the compost stays moist from one end to the other with no dry strip in between.

Fill the fitted pots with coco coir

If you are repotting at the same time as installing the ollas, the 3 blocks of compressed coco coir yield 210 litres of grow medium once rehydrated, enough to fill many pots and a planter. The coir retains the water that the olla delivers whilst remaining well aerated around the roots. Press it lightly against the clay when fitting, as it is this contact that allows the water to transfer.

Replace the lid on each olla after filling it with water

An olla left uncovered loses some of its water through evaporation, collects soil and fallen leaves, and provides mosquitoes with a still surface on which to lay eggs during summer. After each refill, replace the cork stopper on models fitted with one, or lay a small flat stone over the opening of plain terracotta models.

🍶 Glazed neck or bare clay

You have a choice of two finishes. The first has a white enamelled neck sealed with a cork stopper: the enamel closes the pores of the visible section, which therefore loses no water to the air, and diffusion takes place through the lower section of bare terracotta buried in the compost. The second is in bare terracotta all the way up, with a uniform orange tone that blends into a terracotta pot. The principle and installation are the same for both.

🪴 From installation to the first month

Before the first use, leave the olla to soak in a basin of water overnight so the clay is fully saturated, this extends the diffusion time during the first few fills. Next, loosen your compost, push the olla in point-first up to the base of the neck, then firm the soil around it by hand. Water the pot normally on the day you install it, as an olla placed in dry compost will empty very quickly at first. A plant that has just been transplanted will not benefit until its roots reach the clay, which can take up to a month: continue watering from the surface in the meantime.

🧂 Limescale and winter

Minerals from the water gradually build up in the clay's pores, causing diffusion to slow over time. When an olla has almost stopped draining while the compost around it is dry, remove it, fill it with white vinegar, leave it to work, then rinse thoroughly before putting it back in place. Waterlogged terracotta can also crack when it freezes: if your pots spend the winter outside, remove the ollas before the first frost and allow them to dry completely before storing. The guide everything you need to know about ollas covers this mechanism in detail.
