The Power of Seaweed Secrets: A Game-Changer for Plant and Soil Health
Seaweed extracts are widely used in horticulture, agriculture and turf management as plant biostimulants.
Rather than supplying large amounts of primary nutrients like nitrogen, phosphorus and potassium, they are used to support natural plant processes including root development, nutrient use, growth and responses to environmental stress.
Seaweed Secrets combines concentrated Ascophyllum nodosum seaweed extract with humic and fulvic acids to support plant and soil health across lawns, gardens and growing systems.
What Is Ascophyllum nodosum?
Ascophyllum nodosum is a brown seaweed found along the North Atlantic coastline and is one of the most extensively studied seaweeds used in agricultural biostimulant products. Its extracts contain a complex mixture of compounds including polysaccharides, minerals, amino acids, polyphenols and other biologically active substances. The exact composition depends on the seaweed source and extraction process. Research has associated A. nodosum extracts with changes in root development, nutrient uptake, plant growth and plant responses to environmental stress. These effects are generally described as biostimulant effects, rather than the action of a conventional fertiliser.
How Do Seaweed Extracts Work?
Seaweed extracts don't work through a single active ingredient. They contain multiple compounds that can interact with plant physiological processes. Research has shown that A. nodosum extracts can influence:
- Root development and root architecture
- Nutrient uptake and nutrient-use processes
- Plant growth and development
- Antioxidant and stress-response pathways
- Plant responses to environmental stresses such as heat, drought and salinity
- Interactions between plants and beneficial microorganisms
The response can vary depending on the crop, product formulation, extraction method, application rate and growing conditions. This is why seaweed extracts are better understood as plant biostimulants than as a conventional fertiliser or plant protection product.
What's in Seaweed Secrets?
Seaweed Secrets contain a complex combination of compounds rather than acting as a single active ingredient.
| Ascophyllum Nodosum (Kelp) |
Ascophyllum nodosum contains a range of compounds that have been investigated for their role in plant growth and stress responses, including polysaccharides, polyphenols, amino acids, minerals and compounds associated with plant signalling. Research suggests these compounds can influence physiological and biochemical processes in plants, including root development, nutrient use and responses to environmental stress. |
| Humic Acid |
Humic substances can interact with soil and plants in several ways. Research has associated humic substances with changes in root development, nutrient uptake and plant metabolism. Their effects depend on their source, chemical characteristics, concentration and application method. |
| Fulvic Acid |
Fulvic substances are generally more soluble fractions of humic substances and can interact with mineral nutrients and other compounds. Rather than viewing fulvic acid simply as a nutrient carrier, it is more accurate to consider it one component that can influence nutrient interactions and plant physiological responses. |
How Do Seaweed Extracts Work?
Seaweed extracts are different from conventional fertilisers because many of their effects are associated with biostimulation rather than simply supplying nutrients. Research suggests that seaweed extracts can influence plant signalling, root development, nutrient-use efficiency and defence-related responses. The exact mechanisms are complex and are still being investigated.
- Supporting Root Development: Research into Ascophyllum nodosum extracts has reported changes in root architecture, including increased lateral root development in some crops. A stronger root system can help plants explore a greater volume of soil for water and nutrients.
- Supporting Nutrient Use: Seaweed extracts have been associated with improved nutrient uptake and nutrient-use efficiency in a range of crops. This does not mean seaweed extract replaces fertiliser. Instead, it can complement a nutritional program by influencing the way plants acquire and use nutrients.
- Supporting Plant Responses to Stress: Plants naturally respond to environmental stresses such as heat, drought, salinity and cold. Research has found that some A. nodosum extracts can influence physiological and biochemical responses associated with abiotic stress tolerance, including antioxidant activity and water-use responses. The response depends on the crop, product, application rate and environmental conditions.
- Supporting Plant Defence Responses: Seaweed extracts can also act as elicitors, meaning they can stimulate signalling pathways involved in plant defence. Research has reported changes in defence responses following seaweed extract application, including responses associated with certain pathogens and pests. This should not be confused with a pesticide or fungicide. A seaweed product does not directly control a pest or disease in the same way as a registered crop-protection product.
Is Seaweed Secrets Actually a Fertiliser?
The term "seaweed fertiliser" is commonly used, but seaweed extracts and conventional fertilisers serve different purposes. A conventional fertiliser is primarily used to supply nutrients such as nitrogen, phosphorus and potassium. A seaweed extract is generally used for its biostimulant properties and contains comparatively smaller quantities of plant nutrients. Seaweed Secrets should therefore be viewed as part of a broader lawn, garden or crop nutrition program rather than a replacement for appropriate fertilisation.
When and How Should You Apply Seaweed Extract?
Application rates should always follow the current product directions, as the appropriate rate depends on the crop, application method and growing conditions. Seaweed extracts can generally be applied to the soil or foliage, depending on the product formulation and intended use. For established lawns and gardens, regular applications can be incorporated into an ongoing plant-care program. Applications can also be particularly useful around periods of active growth, establishment or environmental stress. Avoid applying more frequently or at higher rates than recommended. More product does not necessarily produce a greater biostimulant response. Seaweed can be incorporated into plant-care programs throughout the growing season.
Common application timings include:
- During active growth: To support ongoing plant development and root activity.
- After establishment or transplanting: To support plants as they develop their root systems.
- Before or during environmental stress: Applications may help support natural plant stress-response processes when conditions such as heat or drought are expected.
- As part of regular lawn care: Regular applications can complement fertilisation, soil management and irrigation programs.
For specific application rates and intervals, follow the directions for Seaweed Secrets.

Seaweed extracts are commonly used in turf management as part of a broader nutrition and maintenance program. For lawns, the focus is on supporting healthy root systems, plant growth and resilience while complementing appropriate fertilisation, irrigation and soil management. Seaweed is not a substitute for correcting underlying problems such as nutrient deficiencies, poor irrigation, compaction, unsuitable mowing practices or soil issues. It works best as one component of a complete lawn-care program. |
Seaweed extracts can be used across a wide range of garden plants, including vegetables, flowers, shrubs, fruit trees and potted plants, provided the application is appropriate for the product. For gardeners, regular seaweed applications can form part of a routine that also includes appropriate fertilisation, watering, soil management and seasonal plant care. Because different plants and growing conditions have different requirements, application rates should be adjusted according to the product directions and intended use. |
