How do I use an Olla irrigation pot?

Ensuring your plants have a sufficient supply of water can be hard going, especially during dry and hot weather spells. Every day, sometimes multiple times a day, you will find yourself topping up your watering can and carefully sprinkling water over individual plants, trying to ensure they've got enough to drink to get them through the day.

Olla irrigation pots are THE alternative to laborious, intensive hand watering. They ensure a constant, trickling supply of water reaches your plants' roots as and when they need it. As long as you keep the watering pot topped up, your plant will never get thirsty!

They require very little maintenance and are very simple to use.

All you have to do is the following:

  • In the space between your plants, dig a hole large enough for your Olla to sit in, ensure the hole is deep enough so the bulb of the pot is entirely covered, but that the top of the stem is still visible ( this ensures you can easily fill it with water and that you don't accidentally step on it).
  • Refill the hole with soil, so your Olla is nice and tightly buried - apart from the top of course!
  • Using a jug or hosepipe, fill your water pot until it's nice and full.
  • Place the little terracotta lid on top - this ensures no soil, debris or wildlife accidentally drops inside.
  • Voila! Your irrigation pot is ready to go, and will supply your plants with water as they need it.

If you have particularly shallow rooting plants, it is possible to bury the Olla pot at an angle, making it a little bit more of a feature, as the water won't have to be delivered quite as deeply.

For the 300ml self-watering spikes, simply pop them into a planter or hanging basket, and push them in as far as you can. 

How does the irrigation pot work?

Natural clay watering pots are incredible really, there's no fancy technology or cogs and reels. It's just clever design, fantastic natural materials and allowing nature to work how it wants to!

As the Ollas are made from unglazed terracotta clay, they're porous, which means water can pass through the material over a period of time, so it doesn't just stay contained inside the pot. 

When the terracotta watering system is placed into the soil it is surrounded by moisture in the soil. This creates a tension, almost like a suction force between the water in the soil and the water inside the Olla. Water also naturally moves from areas of high concentration (wet areas) to areas of low concentration (dry areas) through the power of osmosis.

As plants pull water from the soil, or water is lost from the soil through evaporation, water is naturally released from the irrigation pot - replacing exactly what was lost. If the soil is dry the Olla will naturally release more water, as there's a larger difference in water tension caused by the 'pulling' of the plants roots, as well as the dryness in the soil. But if the soil is wet, the release will be negligible as the water levels between the Olla and the surrounding soil will be very similar.

It needs pretty much no attention from you, all you have to do is ensure it's kept topped up with water each week - perhaps a little more often if it's particularly warm.

 

What are the benefits of using an olla watering pot?

There's a whole host of benefits to using an irrigation pot, they're an excellent choice not only for you, but your plants and garden too,

The benefits include:

  • Time saving and easy maintenance, you don't have to go around watering each individual plant every day, you simply have to occasionally check the water levels of the pot and top it up when needed.
  • They ensure a constant trickling supply of water, directly to the plants roots.
  • They promote deep and dense root growth - roots naturally grow towards their water source, by using an Olla you're ensuring your plants are receiving water from deep in the ground, not from surface soil, this encourages the roots to grow vastly and downwards towards the water source. This will help reduce the risk of root damage too.
  • They're incredibly water efficient, as they're sealed and deliver water deep within the soil, there's no surface evaporation to contend with and they help prevent water run off that comes with surface watering. By using an Olla, you also help prevent your plants roots from going through vicious drying and wetting cycles - the supply of water they get is constant, and the watering pot helps to ensure conditions for your plants roots remain consistent, so they should never become waterlogged or dry out.
  • As the water is being released deep into the soil, the topsoil naturally remains dry, this can help deter the growth of weeds or competitor plants that would otherwise thrive in damp topsoil.

 

How can I ensure my plants are getting the water they need?

Plants can be finicky when it comes to water requirements. Some need a lot more watering than others. That's why Ollas are a great choice when it comes to choosing a watering solution - they give plants exactly what they need when they need it. But, there's a whole host of other options when it comes to water retention in your garden you might want to consider.

Need to target your water delivery to a specific plant or plant cluster? Why not take a peek at our self-watering spikes? These will get a water supply directly to the plants that need it most. Similar to our 300ml versions but with an upturned wine bottle, they can hold more water. 

Got your watering plans under control already? Great! Why not make just a few little additions to your maintenance routine to help keep things a little more efficient? Why not add a sprinkle of organic sheep wool pellets to your pots or top your plants off with a jute mulch mat? Both of these items are excellent at helping retain water and prevent soil water evaporation.

How do you pronounce "olla"??

The "correct" pronunciation is Oh-yah.  Silent LLs, like Paella. However, these are no rule ollas, and you can pronounce them however you like. Here in West Cumbria, we're pronouncing them ollah.

Husky chew proof....so far
My husky has a habit of gutting and destroying any squeaky chew toy I have gotten for her. This one so far has lasted a over a month now I must say it does make her work for a treat when hidden in the center of it. So far all the stitching and parts are attached and like new. The plastic center where you hid the treats is intact, the firmness of it does make it difficult to get the treats you put in hard to remove-so choose wisely and not put in large pieces as there is one of the first pieces still inside the center as even I can't get it out. So my girl she enjoys carrying it around and playing with it so this chew toy is a win for this husky owner

DANGER
DO NOT BUY!!! DANGER! We have had the turtle ones before and then got these. Be we bought two. there is a plug peice in the end that popped out. My dog ate it the first time and had to have emergency surgery because it was stuck in his intestines. We had it removed which cost THOUSANDS of dollars. Also was on vacation when it happened and had to come early when the sitter informed us he was ill. We felt guilty for month! had he got something in our house or yard was it our faults. We saved what they removed which looked like a cork but we dont drink wine. we have a frenchie that doesnt enjoys long walks on the beach if you know what i mean so would not have had access to eat something other places he doesnt relaly go anywhere. This was his favorite toy for a long time so when it got dirty outside, we threw away the first one and took out the second one to replace it . One day i was sitting playing fetch with him when i saw the plug peice come out. I caught it and took it out of his mouth. I IMMEDIATELY RECOGNIZED IT. I ran to grab the zip lock bag the vet gave us with the cork looking item covered in gunk and slime from inside his intestines, ran to the sink to rinse it off and what do you know. mystery was solved. This toy could have killed my dog !

Strong hold
Color: Multi-colored, Color: Multi-colored
Very good product. I’m definitely impressed. I have two German shepherds and this toy is definitely durable and does what it’s made to do. The suction is great. The company even gives you a clear plastic strip that you can actually put on the floor and then put the suction cup on it For better grip. I’ve had suction toys before which was absolutely horrible. This one definitely supersedes all others. The suction comes off once in a while but usually that’s because if my dogs are literally biting on the suction cup part lol. But with confidence. Great product
