How Does AgriSea's Ocean Organics Range Work?

Ocean Organics harness the natural power of New Zealand's native brown kelp seaweed, Ecklonia radiata, which contains over 60 minerals and elements, 12 vitamins, 21 amino acids and complex carbohydrates. Using AgriSea's unique cold-brewing fermentation process, the seaweed is processed without heat, chemicals, freezing or dehydration, preserving sensitive natural hormones, micronutrients and bioactives. We carefully hand-stir these products over several months, allowing the seaweed's organic matter to naturally transform into nutrient-rich biostimulant tonics that your garden will love.

Our Soil+ concentrate is designed to feed beneficial underground microbes, improve soil structure, water retention, nutrient cycling and root growth, while our foliar sprays deliver a nutrient boost directly to plant leaves for rapid uptake and faster recovery from stress. Together, these products build a resilient, self-supporting garden ecosystem. Our products work in harmony with nature – and each other – to produce healthier soil, stronger roots, vibrant flowers, productive vegetables and lush lawns in a safe and sustainable way.

Frequently asked questions

For best results, apply our foliar spray regularly during growth or stress periods (e.g. daily for aphids (for up to 3 days), weekly for potted plants, and every 7–10 days for disease prevention). It is safe to spray often when plants are under attack. Our soil concentrate can be applied during planting and growth spurts to maintain soil and root health.

Yes. Ocean Organics' formulations are organic, non-toxic and safe, making them ideal for home gardens with children, pets and edible crops. They contain no harsh chemicals, and you can harvest or consume fruit and vegetables immediately after application.

Our seaweed concentrates feed beneficial soil microbes, improving soil structure, aeration, water-holding capacity and nutrient cycling. This encourages deeper roots, healthier plants and a more resilient garden ecosystem naturally, without synthetic fertilisers.

Absolutely. Simply dilute the soil or foliar concentrates and water around the roots or spray plant leaves. Container plants benefit from regular weekly feeding in summer as nutrients are leached quickly with frequent watering.

Ocean Organics products are very versatile – they're safe for lawns, flowering plants, bulbs, shrubs, fruit trees, vegetables, herbs and container gardens. Use them as part of regular maintenance or to support plants under stress. Use a weak solution of Seaweed Soil Concentrate on all new plantings to prevent transplant shock.
