Waterpot Spikes

78 reviews

Waterpot Watering Spikes have been designed for your small space indoor plants! Whether you’re going on holiday or you’re just too busy living your life, consistently watering indoor plants can be a challenge.

An adjunct to the Waterpot Ollas when the size of your pot won't accommodate the traditional olla shape, Water Spikes are sleek and easy to install.

The only other item required is a repurposed small, long-necked bottle from the recycle bin that inverts to form a reverse water level indicator.

Available in a boxed set of 4 water spikes, these also make unique gifts for indoor plant lovers.

Indoor plant watering made easy

The Terracotta Water Spikes

  • 100ml capacity - not to be used as a drinks vessel
  • The pack consists of 4 Spikes + instructions
  • Materials: Low fired porous Terracotta clay 
  • Size: Diameter 4.5cm Diameter x 18cm Height  
  • Designed in Australia, hand-cast in China
  • All products shipped are protected by 100% recyclable and/or biodegradable void fills and wrappings for the benefit of the Planet! 

Why should I use Indoor Plant Water Spikes?

  1. Water is delivered directly to the root zone 
  2. Filling the reservoir with water when needed couldn't be easier!
  3. Provides indoor plants with steady moisture 
  4. Low tech and easy to use 
  5. Retain Nutrients: This is a closed system of watering the plants that will not allow the water to drain elsewhere, this can reduce nutrient loss within the soil.
  6. Saves Water: When a plant is overwatered, the excess water drains from the pot (if drainage is provided). This Spike provides water to the soil at the plant roots where they can draw the water they require. Since the spike is surrounded by soil, the water within the Spike will not evaporate.
  7. Saves Time: Watering your plants can take some time to do, especially when you have a lot of them. Since they are self-watering, all you need to do is keep an eye on the reverse water level in the bottle or ask your plant nanny to do so whilst you're away on holidays!
  8. Prevent Root Rot: Since this system will only water the plant when the soil is dry, it will be a lot easier to get the water further into the soil without the water sitting constantly around the roots. This will encourage the roots to grow, which will give you a healthier plant. Over-watering is the number one plant killer (other than under-watering!)

How do I use the Waterpot Spikes? 

All boxed sets of 4 spikes come with easy to follow instructions. The instruction sheet should be referred to before use. You insert, fill with water and invert a bottle. Too easy! An Installation video can be found on our Youtube channel

Simple, effective, affordable & easy to use. Based on the science used in traditional Olla irrigation, this is a modern solution for the indoor plant gardener! Read more about The Science of Olla Irrigation


PLEASE NOTE: As these are hand slipcast Terracotta items, there may be variations between one vessel and another in terms of colour, weight and shape due to the nature of kiln firing and the natural qualities of Terracotta clay. 

Highly recommended for the installation of the Waterpot Spikes is the simply amazing indestructible marine-grade aluminium alloy Narrow Garden Trowel by Lelox -

Prefer lids for your Spikes? Whilst we recommend the bottles for efficient watering of your plants, we have sets of 4 Terracotta Flat Lids available for that unobtrusive look

Great products and service!

I don’t have a tap near this side of the house so having these has helped me immensely. The service was also wonderful. I made a mistake with my address on the order and it was returned but they were super speedy and communicative about fixing the problem and sending it back. Would definitely recommend to a friend and will continue to shop here.

Waterpot spikes - 3 weeks and counting!

Up on the rooftop are a wealth of information! I Inherited some handmade bluestone basket pots (think grouted together!) From my grandparents estate, and planted some strawberries in them. I was surface watering them daily only to come home to find wilted plants. Up on the rooftop sent me information to prepare, what bottles to look for to recycle for water reserves, and tips like mulching. I set up my strawberry pot 3 weeks ago, and of the 330mm great northern bottle that was full at the start, the plants are happy as Daisy's and Only used about an inch of the water reserves! Not only do I have happy plants but we are using less water at the same time.

Drought proof -almost!

These have secured the water supply to my tomatoes right to the roots so well, that I decided to use them on all my pots! The benefit of being able to place them within established plants even though the plant has been in the pot for a few years, means that watering pots has been made easier. Almost a drought proof solution! - you still have to check them, but far less often.

Awesome product

I purchased 20 water spikes. I use them in my outdoor pots. I have not had them for very long but they appear to be working beautifully. I will but more as soon as I can afford them:)

Great. I have 8 of the waterspout spikes in pot plants, & they are fantastic. They do the job perfectly. Exactly what I needed.
