Seaweed Plus NZ Made Commercial Seaweed Extract for Growers
Seaweed Plus – NZ-Made Commercial Seaweed Extract for Growers
Ascophyllum nodosum + Humic & Fulvic Acids for Horticulture, Viticulture & Cropping
Seaweed Plus is a high-concentration, NZ-made commercial seaweed extract designed for professional growers who want more than a generic seaweed tonic.
Unlike most seaweed products on the New Zealand market, Seaweed Plus combines Ascophyllum nodosum seaweed extract with Lazerhume liquid humic and fulvic acids to support plant stress resilience, root development, and nutrient efficiency together, in one practical, commercial formulation.
Seaweed Plus is widely used in New Zealand vineyards and intensive growing systems where consistency, efficiency, and reliability matter.
What Makes Seaweed Plus Different
Many seaweed products focus solely on plant hormones. Seaweed Plus is formulated to work at the soil–root–plant interface, where long-term performance is determined.
Dual-Action Commercial Formulation
Ascophyllum nodosum seaweed extract
Naturally rich in cytokinins, auxins, and betaines
Supports plant stress response and recovery
Encourages balanced growth rather than forced stimulation
Lazerhume humic & fulvic acids
Improve nutrient chelation and availability
Support root development and nutrient uptake
Enhance soil biological activity and nutrient cycling
Together, this blend supports plant resilience and nutrient efficiency, not just short-term foliar response.
Designed for Commercial Growing Systems
Seaweed Plus is highly concentrated, allowing low application rates per hectare compared with many retail and garden-focused seaweed products.
It is formulated for use in:
Vineyards
Orchards
Vegetable and row cropping
Intensive horticulture systems
Seaweed Plus integrates easily into existing fertiliser and spray programmes without adding unnecessary complexity.
Why Growers Use Seaweed Plus
Improved Stress Tolerance
Supports crops through:
Heat and moisture stress
Frost events and cold snaps
Transplant and establishment shock
Nutritional and chemical stress
Stronger Root Systems
Encourages root growth and root activity
Supports early establishment and uniform crop development
Improves the plant’s ability to access water and nutrients
Better Nutrient Efficiency
Humic and fulvic acids help mobilise nutrients in the soil
Supports uptake of nitrogen, phosphorus, and trace elements
Helps growers get more value from existing fertiliser inputs
Built for Consistency
Seaweed Plus supports natural plant processes rather than forcing growth. Results depend on crop type, timing, and growing conditions, making it a reliable agronomic tool rather than a one-off stimulant.
Proven in New Zealand Vineyards
Seaweed Plus is most commonly used in NZ viticulture, where growers demand:
Consistent vine performance across variable seasons
Strong root function and nutrient balance
Improved stress tolerance without excessive vegetative growth
Its use in vineyards reflects its suitability for high-value crops where reliability and control are critical.
How Seaweed Plus Works
Seaweed bioactives support plant stress signalling and recovery pathways
Humic and fulvic acids improve nutrient mobility and root interaction
The combination supports a healthier rhizosphere and more efficient plant metabolism
This systems-based approach aligns with modern agronomy that integrates biology, chemistry, and soil function rather than treating them separately.
How Seaweed Plus Compares to Other NZ Seaweed Products
Many seaweed products in New Zealand focus on:
Single-ingredient seaweed extracts
General plant tonics or soil conditioners
Broad biological claims without nutrient efficiency support
Seaweed Plus is different because it:
Is formulated specifically for commercial growers
Combines seaweed + humic & fulvic acids in one product
Targets both plant response and nutrient uptake efficiency
Is NZ-made for local soils and production systems
This makes Seaweed Plus a practical alternative to seaweed-only products where growers want measurable performance, not just general stimulation.
Application & Compatibility
Suitable for foliar and soil application
Compatible with most fertilisers and crop protection products
Concentrated formulation supports low use rates
Best used as part of a planned crop nutrition programme
(Always conduct a jar test prior to tank mixing.)

Why Seaweed Plus Costs More.
Seaweed Plus is a commercial-grade, NZ-made biostimulant designed for professional growers who demand reliable, consistent results.

Frequently Asked Questions
What is Seaweed Plus used for?
Seaweed Plus is a commercial biostimulant used to support plant stress resilience, root development, and nutrient efficiency in horticulture, viticulture, and cropping systems. It is commonly applied during establishment, active growth, and periods of stress.
How is Seaweed Plus different from other seaweed products in New Zealand?
Most seaweed products contain only seaweed extract. Seaweed Plus combines Ascophyllum nodosum seaweed extract with humic and fulvic acids, supporting both plant physiological response and soil–nutrient interaction in a single formulation designed specifically for commercial growers.
Is Seaweed Plus a fertiliser?
No. Seaweed Plus is not a fertiliser. It does not supply significant nutrients, but helps plants use applied fertiliser more efficiently and cope with environmental and management stress.
What type of seaweed is used in Seaweed Plus?
Seaweed Plus uses Ascophyllum nodosum, a seaweed species widely studied and used globally for its natural plant bioactive compounds, including cytokinins, auxins, and betaines.
Why does Seaweed Plus contain humic and fulvic acids?
Humic and fulvic acids help improve nutrient availability, root interaction, and soil biological activity. When combined with seaweed extract, they support stronger root systems and improved nutrient uptake efficiency.
Is Seaweed Plus suitable for vineyards?
Yes. Seaweed Plus is widely used in New Zealand vineyards, where growers value its ability to support vine resilience, root function, and nutrient balance across variable seasonal conditions.
Can Seaweed Plus be used on crops other than grapes?
Yes. Seaweed Plus is suitable for orchards, vegetable crops, row crops, and intensive horticulture systems, and can be integrated into existing commercial nutrition programmes.
How is Seaweed Plus applied?
Seaweed Plus can be applied as a foliar spray or soil application and is commonly used alongside standard fertiliser and crop protection programmes.
