Tallus is a highly concentrated, 100% organic liquid seaweed biostimulant designed for lawns, plants, and houseplants.

Our formula is derived exclusively from sustainably harvested UK Ascophyllum Nodosum. The extraction process preserves the natural hormones, micronutrients, and essential compounds needed for cellular plant growth. It is a clean, professional-grade solution designed to improve overall plant health from the soil up.

Tallus was founded by Kieren, a professional gardener operating in North West London. After consistently using commercial seaweed products for his clients, he realized the market was flooded with cheap, mass-grown alternatives.

Driven to find something better, his research led him to Ascophyllum Nodosum—a highly potent seaweed with exceptional benefits for plant health. Because a concentrated, British-made version didn't exist on the market, he partnered with industry experts and scientists to develop a data-backed formula. He still uses it on his clients' gardens today.

Think of Tallus as vitamins for your garden. It contains over 60 naturally occurring trace minerals and bioactives that standard fertilizers lack.

Instead of just forcing temporary top-growth, Tallus works below the surface to rapidly strengthen root structures. This deep cellular support acts as a natural shield, giving your plants and lawn the resilience to withstand extreme weather changes, recover from drought, and naturally fight off disease.
