Ollas
The olla regulates water flow according to each plant's needs
You love your plants. You really do. But between your life, your projects, and that series you still haven't finished, watering sometimes (often) falls through the cracks. That's exactly why we created our ollas. These little terracotta objects — also known as ollas — are here to take over when your memory lets you down. And honestly, they do it with style.
A terracotta olla is a bit like the quiet companion your houseplants never knew they needed. Fill it up, pop it in the pot, and it takes care of the rest. No guilt, no yellowing leaves giving you the side-eye. Just happy plants and a decorative object that earns its place in your home.
What is an olla for houseplants?
An olla — or oya — is a handcrafted terracotta water diffuser that you plant directly into your plant's pot. It's actually one of the oldest self-watering systems in existence: traces of it go back thousands of years in agriculture. What's different about ours is that they're designed entirely for indoor use, with refined finishes that make them genuine decorative objects.
In practice, the microporous terracotta allows water to pass through very slowly via micro-pores invisible to the naked eye. Your plant helps itself whenever it's thirsty, no intervention needed on your part. No programming, no sensor, no cables. Just porous ceramic and water. Simple, effective, elegant.
This capillary auto-irrigation system is particularly well suited to houseplants: it respects their natural rhythm, prevents both excess and shortfall, and fits discreetly into any pot.
How does this self-watering system work?
The principle is as simple as it is brilliant. The microporous terracotta acts like a natural membrane: the water inside the olla slowly passes through the porous ceramic walls and moistens the substrate around the roots. Your monstera is thirsty? It helps itself. Your ficus is feeling fine? The water stays in the diffuser. Pure micro-irrigation, zero technology.
Where a watering can delivers a big splash all at once — sometimes too much, sometimes not enough — this self-watering system releases water continuously, gently, at exactly the pace your plant needs. The kind of care your plants deserve, with no botany degree required.
The result: fewer roots rotting from overwatering, fewer leaves dropping from lack of hydration. And above all, genuine peace of mind for you.
The everyday benefits of ollas
Let's be real. In the morning, you walk past your plant and glance at the olla. If it's empty, you fill it up. If it's still full, you get on with your coffee. That's genuinely all there is to it.
Generally, filling your self-watering system once a week is plenty — though it can vary depending on the season and how thirsty your plant is. In summer, when it's warm and the soil dries out faster, you might top it up twice. In winter, some ollas easily last ten days. You'll quickly find your rhythm, no stress involved.
And then there are those moments when automatic watering for houseplants becomes genuinely essential:
Holidays: fill your olla up before you leave and it will slowly release water throughout your absence. Depending on the plant and the season, it can cover a full week — sometimes more.
Hectic weeks: when your mind is elsewhere, your plants stay hydrated without you even thinking about it.
Long weekends: no more asking your neighbour to water your plants while you're away.
And between us, an olla isn't just an accessory you hide in the pot. It's a beautiful object that peeks out above the foliage, adding a touch of colour or texture. You choose it as much for what it does as for what it looks like.
Which olla should you choose for your plants?
Good news: the choice is genuinely straightforward. The only technical thing to keep in mind is the size of your pot. After that, it's purely a matter of style. You can browse our full range of ollas on our website: www.pepinplantcare.com

Your questions about ollas
What is an olla?
An olla (also called an olla) is a handcrafted terracotta water diffuser that you plant directly into your plant's pot. The porous ceramic lets water seep through very slowly, and your plant drinks whenever it's thirsty. No programming, no sensor, just terracotta and water. The principle is as old as time — and it still works just as well.
Are ollas actually effective?
Yes — and it's not just us saying so. The principle of porous ceramic slowly releasing water has been used in agriculture for millennia. The practical benefit: this self-watering system prevents both overwatering (roots rotting) and underwatering (droopy, sulking leaves). Your plants get exactly what they need, even when you forget. Especially when you forget. As a bonus, this capillary irrigation method uses less water than conventional watering: the water goes straight where it's needed, without evaporating from the surface.
We'd rather be straight with you. ollas do have a few limitations worth knowing about: they're a small initial investment compared to a simple watering can. In the first few days, it can be useful to keep an eye on the water level to understand your plant's consumption rhythm. And for very small plants in pots under 8 cm, even our mini ollas can be a bit oversized. In every other case, they do exactly what we ask of them.
How to use ollas to water your plants?
Three steps, no more:
1. Plant the olla in your plant's soil, pointed end down, leaving the neck above the surface.
2. Fill the olla with clean water all the way to the top.
3. Watch your plants grow, effortlessly!
Expect around a week's autonomy depending on the plant and the season. In summer, you might refill twice. In winter, some ollas last ten days or more. You'll find your rhythm quickly.
What is the most effective watering system?
There are several options out there: manual watering, wick reservoirs, electric drip systems… Among them, terracotta ollas stand out for their simplicity and naturalness. No electricity, no tubes, no programming. The porous ceramic irrigation system automatically adapts to the plant's actual needs, making it one of the gentlest and most water-efficient methods for houseplants.
How do you water your plants while you're on holiday?
That's exactly the olla's superpower. Fill it up before you leave and it will slowly release water throughout your absence. Depending on the plant and the season, this self-watering system can easily cover a week — sometimes even longer for low-thirst plants.
How do I care for my olla?
Rinse the olla with clean water now and then to remove any mineral deposits. And that's it!
An olla is the joy of seeing your plants thrive without watering becoming a chore. A beautiful terracotta object, one simple gesture a week, and plants that will never hold a grudge again. All that's left is to pick your colour.
