Designed to make your plant-care easier

Quenching your plant's thirst is an art form. But fear not, we're here to help! Our potting soil ensures your soil stays just right, neither too dry nor too wet.

The structure and components of our potting soil hold onto the perfect amount of water for your plants. Less watering worries, more plant pampering!

Full of microbial life

Our soil is bioactive and teeming with microbial life thanks to fresh worm castings.

It can be home to helpful critters like springtails, isopods, and the predatory mite "Macrocheles robustulus" – what awe-inspiring name! Springtails and isopods help convert decomposed matter into nutrients without interfering with the plants. The predatory mites specialize in attacking the eggs, larvae, and pupae of fungus gnats, thrips, and fruit flies. So, it's like having your own personal defense line!

While the soil is being cleared of adult worms, the eggs can still hatch in the soil. WORMS IN MY SOIL? YES! That's a good sign! It signifies incredibly fresh worm castings. Earthworms feast on decaying plant matter, keeping the soil airy and producing fresh nutrients. They also regulate their own population (along with springtails, isopods, and predatory mites). So, once there's no more decaying matter, they'll gradually disappear.

Our commitment to responsible production.

At Sybotanica we not only want to make plants happy, but people happy as well. In our production team we exclusively hire people with a distance from the workforce, and help them rehabilitate to the normal working life.


Take Peter for example:

Peter has been with Sybotanica since the 1st hour, and has now been promoted to head of production & a permanent contract! Where he was the first employee, he now manages a team of 3 production workers.

What makes this achievement even more impressive is that Peter achieved all this with only 10% visibility! đŸ•¶ïž With a few minor adjustments to his working environment, Peter is able to perform his job 100%.

Peter has now been through two moves and knows all the ins & outs of Sybotanica. He can even feel by the potting soil which variety it is. That's quite a challenge with 16 different mixes!

We are confident that Peter will keep production running smoothly in the coming years too! đŸ’Ș

We don't think peat is so neat!

It becomes too compact over time, leading to a state where it no longer absorbs water.

That's why we opt for coconut fiber and worm castings, keeping your potting soil delightfully airy and usable for much longer. Much more environmentally friendly in its use & less CO2!

Potting Soil That’s Honest, Expert-Backed, and Seriously Good

When it comes to potting soil, you deserve more than vague promises and mystery ingredients. That’s why at Sybotanica, we do things differently. Every bag of SYBASoil is transparently sourced—we show you exactly where each component comes from, how it functions, and why it’s included. From the airy structure of our coconut coir potting mix to the slow-release nutrients tailored to specific plant families, our soil is designed for plant health and consumer confidence. We even go a step further: with a trained biologist on our team, we’re able to answer your toughest questions about plant care, soil chemistry, and everything in between. Whether you’re a beginner or a seasoned plant collector, our potting soil isn’t just good—it’s great, with results you’ll see in brighter foliage, stronger roots, and fewer problems. When you want potting soil that performs and a brand you can trust, Sybotanica has your back.

What Makes SYBASoil Potting Soil Truly Stand Out

Transparent Ingredient Sourcing

You should know what’s going into your pots—and into your plants. That’s why every blend of SYBASoil is made with full ingredient transparency. We clearly list where each component of our potting soil comes from, from the sustainable coco coir sourced as a renewable byproduct, to the bark, perlite, or compost used to create structure and nutrition. Our mission is to eliminate the guesswork and greenwashing so common in the gardening world. By knowing exactly what’s in your soil, you gain trust and peace of mind—without sacrificing performance.

A Biologist on Board to Back You Up

We don’t just guess what’s good for your plants—we ask the experts. At Sybotanica, we work with a trained biologist to ensure our potting soil formulas are supported by real plant science. From nutrient ratios to substrate composition, every element of our SYBASoil blends is grounded in biology, not marketing. Got a question about root rot? Want to know why your soil stays wet too long? We’ve got the answers. Whether you’re troubleshooting or just curious, you’re never alone when you choose Sybotanica.

High-Quality Soil That Supports Plant Health from Day One

The Ideal Soil for Indoor Plants

SYBASoil isn’t just about sustainability—it’s about performance. Our potting soil is optimized to function as the best soil for indoor plants, with excellent drainage, air flow, and moisture regulation. This means your plant roots can breathe, grow deep, and avoid the stressors caused by poor-quality, compacted soil. Whether you’re potting a tropical beauty or a hardy cactus, we’ve got a blend made specifically for your plant’s natural needs. It’s houseplant care made easy, clean, and incredibly effective.

Built on Sustainable, Eco-Friendly Choices

Of course, great performance shouldn’t come at the cost of the planet. That’s why every SYBASoil blend is proudly eco-friendly potting soil. We use peat-free, renewable materials like coconut coir potting mix to build healthy structure and smart moisture retention. Our soil is hand-mixed in our in-house social workplace, supporting fair labor and minimizing environmental impact. The result? A premium soil that’s good for your plant, better for the earth, and best for growers who care about both.

How much soil do I need?

Check out this pot volume calculator tool to calculate how much Hoya Mix you need.

What are the SYBASoil mixes made of? How can I make my own mixes at home?

On each SYBASoil mix page in the description is a section 'Ingrediënts & recipe', there you can find what any mix contains and how to mix it yourself!

Why is the soil shipped moist?

Our soils are packaged and shipped slightly wet. This is to help ensure the quality of the mix. Most of our soil components need to be slightly wet to maintain their quality.

A good example is our worm castings. Worm castings need to remain slightly wet to ensure all the beneficial soil microfauna stay alive. These microfauna help ensure happy and healthy plants!

When do I need to re-feed the soil?

The nutrients in SYBASoil will run out in ~6 months on average.

Check out our fertiliser line SYBASupport.

How long does SYBASoil stay fresh?

You can store SYBASoil for about 2 years. Make sure to store it cool, dark and closed off.

The effectiveness of the nutrients can degrade over the years. Simply add some fresh worm castings to give the soil new life.

How to recycle SYBASoil packaging?

Our packaging can be recycled at your local plastic recycling facility.

You can also re-use it for storage, or leave a little soil and use it as a propagation box!

Do I need to sterilise SYBASoils?

No, this is something we don't do and generally don't recommend, since most our soil mixes contain worm castings, these provide many beneficial microfauna we like in our soils!

When the soil is sterilized these beneficial microfauna would die. These microfauna ensure healthy and happy plants.

Should I add anything to SYBASoil?

Unless you use the Base Mix, you don't need to add anything. You can always experiment to see what works best for your plant and specific situation!

SYBASoil has 180 days of fertiliser, after that you can try our SYBASupport range.
