Soil & Microbe Booster 3L Pouch

Our biochar and frass dream team are back and bigger than ever. This 3L pouch means you can start dishing those microbes out amongst your outdoor plant fam. Enough for the indoor crew, the balcony crew and that lifeless bed around the side of the house.

Can be stirred through new potting mix when repotting, or sprinkled around the root ball to bring life to old mixes. Also great to add to composts to speed up decomposition.

Here are a few reasons to add this double act to your Plant Care kit:

• You don’t have to be rich but your soil should be. Frass holds about 240 million microbial colony forming units per gram. It holds up to 200 times more nutrients than worm castings or compost with more diversity of microbes too. They bring life to your potting mix by improving the structure of the soil and providing nutrients to your plants as they break down organic matter.
• Biochar keeps plants kicking through dry spells and overwatering. It boosts the capacity of soil to hold nutrients and water, complementing the richness of frass.
• Frass is full of mainstream and indie hits. On its own, it boasts a nitrogen-phosphorus-potassium (NPK) ratio of 4:2:2. But it’s still full of those underrated trace nutrients to help your plants flourish: iron, copper, zinc and so much more.
• It’s got some good chitin; the insect exoskeletons that are a natural addition when making frass. This secret weapon activates your plant’s natural defences against pathogens, like the ones that cause root rot. It increases the availability of nitrogen to your plants.

Both are sustainably sourced, carbon-negative and Australian-made.

Separately, frass and biochar do good things. Together, they’re an iconic duo.

Please note: We cannot ship the potting mix into Western Australia, Northern Territory or Tasmania due to quarantine restrictions
