Using Seaweed Secrets provides numerous benefits for your garden and lawn:

Benefit	Description
Nutrient-Rich Formula	Seaweed, specifically Ascophyllum nodosum, is packed with 77 minerals, 17 amino acids, complex sugars, and chelating agents. Combined with high-quality Humic and Fulvic Acid, this nutrient-rich solution boosts soil health, helping plants thrive. Kelp is a vital soil enrichment product that promotes healthy plant development, making it ideal for lawns, trees, and garden plants.
Improved Soil Health	Seaweed improves soil structure and fertility by enhancing moisture retention, aeration, and drainage. This leads to healthier root systems and better nutrient uptake, fostering stronger plants.
Enhanced Plant Growth	The growth-promoting hormones in liquid seaweed stimulate plant growth, resulting in increased leaf and stem growth, improved flowering and fruiting, and overall plant vigour. It helps boost plant development, making it an essential addition to any garden or lawn care program.
Stress Tolerance	Seaweed extracts contain natural compounds that help plants endure environmental stresses, including drought, heat, cold, and disease. These compounds boost plant resilience, helping them recover from adverse conditions and thrive.
Increased Nutrient Absorption	Seaweed's organic compounds act as chelating agents, improving the availability and absorption of nutrients, ensuring your plants get the maximum benefit from the soil. This leads to more productive and healthier plants.
Disease & Pest Resistance	Seaweed extracts enhance the plant’s natural defences, making them more resistant to diseases and pests. It helps reduce the need for chemical pesticides and fungicides, promoting a more eco-friendly approach to plant care.
Environmental Sustainability	Liquid seaweed is a sustainable, eco-friendly fertiliser derived from renewable marine resources. It does not contribute to water pollution and helps maintain beneficial soil organisms, making it a safe and responsible choice for your lawn and garden.

By improving soil structure, increasing moisture retention, and supporting beneficial soil organisms, Seaweed Secrets creates an ideal environment for plants to thrive.

The Science Behind Seaweed Secrets

Seaweed Secrets is based on the combined action of cold-processed kelp extract, humic acid, and fulvic acid, acting as natural biostimulants and nutrient chelators. It works by:

Stimulating root zone microbes to convert bound nutrients into plant-available forms
Improving Cation Exchange Capacity (CEC) in the soil, aiding nutrient retention
Enhancing stress tolerance through cytokinin and auxin compounds naturally found in seaweed
Supporting nutrient absorption across a wide pH range
Strengthening plants’ natural defence mechanisms, reducing reliance on synthetic pesticides
