Benefits of organic compost
Unlike chemical fertilizers, worm castings release their nutrients slowly. Chemical fertilizers are usually quick-release and create a surplus in nutrients, followed by a drop. Due to the microbial life in the worm castings there is a constant steady supply of nutrients. Chemical fertilizers are very prone to water-washing, by watering the soil a lot of nutrients get dragged out of the soil medium and away from the roots. Worm castings is very resistant to this phenomenon

Microbial life
The bacteria and fungus naturally present in the worm castings create a strong basis for a healthy plant. The soil is an ecosystem in itself and there is a constant exchange and flow of nutrients, minerals and other organic components. The microbial life helps plants with the uptake and regulations of the macro- and micronutrients.

Socially 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! 🕶️ 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! 💪

FAQ

Can worm castings be used year-round for fertilizing?
Worm castings is a natural, complete fertiliser for your plants. It is the perfect replacement for chemical fertilizers, which can often burn your plant's roots due to their high concentration of minerals and salts.
Unlike liquid fertilizers, worm castings can be applied throughout the year without the risk of burn!

Is worm castings safe for my animals / children
Worm castings is a natural product and completely safe for animals, for example in a terrarium. However we do not recommend eating it, and keep it out of reach of children (yes, we have gotten this question before..)

What do we feed the worms?
Since worm castings are, quite literally, worm poop, it is common sense that feeding the worms high-quality food results in high-quality castings!
Organic dead plant matter, food waste, kitchen scraps, or other yard waste form the majority of the worms' diet.

Why choose worm castings over compost?
Though these products are similar, there are a few significant differences between compost and worm castings.

Worm castings exclusively consist of worm manure, while compost (while sometimes also containing worm castings) also contains lots of other decomposing plant waste and organisms.

The reason we prefer worm castings over compost is that it is a much more concentrated source of essential nutrients. Compost is also usually a lot more heavy and allows for little airflow, where worm castings has a better structure.

It also contains a much more versatile range of microorganisms, which are highly beneficial for plant health.
