If there were a superfood for soil, Seamungus Green would be it. While flashy products come and go, this humble seaweed and chook poo combo has quietly transformed tired veggie beds into jungle-esque tomato patches—and turned hesitant first-timers into bold backyard growers.

A quiet revolution under the mulch

Not long ago, a customer came in feeling defeated. Her garden wasn’t “bad” – just kind of flat. Tomatoes stayed small, lettuce bolted early, and nothing seemed to thrive no matter how much she Googled. We sent her home with Seamungus Green and a shovel.

Two months later, she was back – photos in hand, grinning like a mum with a fridge covered in kids’ artwork. Her garden looked alive. Bees buzzing. Leaves glistening. Flowers blooming. Sometimes you don’t need to do more—you just need something that works with what you've already got.

Why local soil loves seaweed

South Australia's soil can be tricky—compacted in places, sandy in others, and often short on the rich, loamy goodness that plants love. Seaweed is the quiet partner here. It doesn’t just feed plants—it conditions the soil itself.

Seaweed contains natural growth stimulants and over 60 trace elements that help break up clay and build structure in sandy soils. With Seamungus Green, that’s paired with the slow-release nutrition of chicken manure and fish emulsion—it’s like compost on cruise control.

How to use Seamungus Green (and when to do it)

You don’t need a PhD in horticulture. Just scatter it generously around your plants or mix it into the top layer of soil before planting. For pots, try blending a small amount into your potting mix for an extra kick. And yes—it’s suitable for natives, too.

If your garden’s had a long, hot summer (and maybe you’ve neglected it a bit), mid-autumn is the perfect time to revive tired soil and prep for winter greens, garlic, or a fresh herb corner. Seamungus Green helps restore life—not just feed it.

If you’re still unsure, ask yourself this:

Can your garden afford to keep guessing?

Or would you rather use something time-tested by locals, made with real ingredients, and backed by people who’ve dug into South Australian soil for decades?

That’s the beauty of Seamungus Green—it doesn’t promise miracles. It just delivers results you can see, feel, eat, and be proud of.
