Waterpot Spikes Installation & Information

For indoors or outside use, the Waterpot spikes are ideal for plants that need a consistent water supply.

Simply insert, fill, invert.

The Waterpot Spike fits between your plant and the pot wall. Water seeps steadily through the semi-porous ceramic, slowly wicking into the soil below the surface.

At a glance, a low water level in the bottle tells you it’s time for a refill. These Spikes have been designed to accommodate smaller bottles to provide a discrete, elegant solution to watering your houseplants.

We've designed these spikes to be used in indoor applications, however they can be used with equal success in pots outdoors where a bottle can be safely upended into the neck opening. We would recommend one spike per pot plant in the same way as you would use them indoors. Where larger pots are concerned, we recommend the use of the Waterpot ollas in the main range.


The Waterpot Spikes work on the olla principle where a low-fired terracotta vessel is buried in the ground and leaches water into the surrounding soil at the root level. More information can be found on our website The Science of Ollas Irrigation 


1x long-necked bottle per spike 200ml - 360ml recommended


Water your plant well before preparing to install the Waterpot Spike

Soak the Spike in water for an hour prior to burying it. Spike should be fully saturated.


Dig a hole in the soil before slotting the watering Spikes into the soil.

Do not attempt to push the Spike into your pot soil without preparing
a hole as you are likely to damage it.


Insert the damp watering Spikes into the wet soil with the open-top sitting flush with the soil level (recommended) or leave the collar above the soil. The more of the Spike buried, the less evaporation from the
Spike surface will occur.

The deeper the Spike, the more stable it will be, the more moisture will get to the planting media as a larger surface will be in contact.Water travels through the soil on contact, so pack the soil around the Spike firmly.


Fill the Spike with water.


Half fill the long-necked bottle with water then flip it over into the Waterpot Spike opening.

TIP - cover the opening of the bottle with two fingers when you
invert it to prevent too much spillage.


Remember to place the bottle straight upright. Do not have it tilted or slanted as this will not be stable and the bottle may tip over.


Check the bottle periodically to ensure they still have water.

You don’t need to take out the stake, just lift the bottle out and refill the bottle when it is empty.
