Sunshine Coast Seaweed Fertilizer – Cultivating Growth the Coastal Way
What began as a small, sustainable harvest of naturally beached seaweed has grown into one of the Sunshine Coast’s most thoughtfully run micro-enterprises. At Shaffer Farms, we believe value begins with integrity—of the land, the sea, and the relationships we build through our products.

Sunshine Coast Seaweed Fertilizer is crafted using traditional, low-impact harvesting methods governed by provincial bylaws. We collect only naturally shed seaweed from the upper tidal line, allowing ecosystems to thrive untouched below. From there, the seaweed is carefully rinsed, chopped, and slow-fermented over a 6-month period in aerated tanks—no shortcuts, no synthetic additives. The result? A biologically active concentrate packed with micronutrients, growth hormones, and beneficial microbes.

Originally brewed for use in our own garden beds and ceramic herb containers, the fertilizer quickly gained a local following. Now, it serves gardeners, growers, and homesteaders across the region who are looking for a sustainable boost that respects the earth as much as it feeds it.

We’re proud that our product isn’t just organic—it’s oceanic, ethical, and deeply local. For product details, usage tips, and to place an order, visit us at:
