If you’ve ever brought in truckloads of manufactured soil only to find your plants struggling, you’re not alone. Most commercial mixes - though convenient - are sterile, lacking the life and biological activity that fuels healthy plant growth.

But the good news? You can bring these inert mixes back to life. With a few smart amendments and the right organic inputs, you’ll transform them into living, nutrient-rich soil that supports vibrant, resilient plants.

Here’s how to do it.

🌿 1. Start with Quality Compost

Even the best potting mix benefits from the addition of mature compost. We recommend Living Farms Australia Premium Compost - a high-quality, Aussie made blend that’s brimming with beneficial microbes, humus, and slow-release nutrients. This compost boosts water retention, improves structure, and provides the microbial diversity needed to kickstart soil life.

How to use: Mix compost through the top 15-20cm of potting mix or manufactured soil at a ratio of about 1 part compost to 3 parts soil.

🌾 2. Feed the Soil Biology

Once you’ve added compost, it’s time to feed the microbes. This is where Plant of Health Fertilisers shine. Their organic mineral-based products supply trace elements and stimulate microbial activity without burning tender roots.

🪨 3. Rebuild Soil Structure with Rock Minerals

To supercharge your mix long term, incorporate Earthlife Minerals. These volcanic rock dusts and soil conditioners are packed with slow-release trace elements and silicas that improve soil structure and feed microbial life over time.

Try:

Earthlife Garden Mate – a blend of rock minerals, gypsum, and natural microbes that condition heavy or tired soils.
Earthlife Rock Minerals – ideal for adding trace elements to sandy or low-fertility mixes.

How to use: Sprinkle through the mix at recommended rates and water in with seaweed or compost tea for best results.

🐛 4. Add Microbial Inoculants

Once the soil has food, structure, and organic matter, it’s time to introduce even more life.

Plant of Health Living Microbes — Microbes help plants access nutrients in the soil.

Compost Tea or Microbial Inoculants – you can brew your own or buy ready-made microbial blends to spray onto the soil surface.

These additions help colonise your potting mix with the fungal and bacterial allies that plants depend on to access nutrients and fend off disease.

🌼 5. Mulch & Moisture Management

Don’t forget to mulch with straw, bark, or sugarcane to protect the living soil underneath. Mulch helps retain moisture, stabilise temperature, and provide habitat for soil organisms.

Water deeply and regularly - but avoid overwatering. Living soil needs air as much as it needs moisture.

🔄 Maintenance: Keep Feeding the Life

Living soil is like a sourdough starter - it needs a bit of regular feeding to stay active. Continue monthly applications of:

Seaweed or fish emulsion
Diluted worm juice
Compost top-ups
Organic slow-release fertilisers (like Plant of Health Organic Link)
