Why Choose Seaweed Plus?
Healthy Plants Perform Better
Successful cropping systems rely on more than fertiliser alone.
Strong roots, healthy plant development and the ability to respond to changing environmental conditions all contribute to consistent crop performance.
Seaweed Plus has been developed to support these natural plant processes, helping growers build healthier, more resilient crops throughout the growing season.
Originally developed for New Zealand's viticulture industry, Seaweed Plus has since been successfully adopted across a wide range of horticultural and commercial cropping systems where consistent crop performance is a priority.
The goal isn't simply to grow bigger plants.
The goal is to improve the performance of the entire cropping system.
How Seaweed Plus Supports Crop Performance
Healthy crops depend on many natural processes working together.
Strong root development, efficient nutrient uptake, healthy plant growth and the ability to respond to environmental stress all influence crop performance throughout the season.
Seaweed Plus has been developed to support these natural plant processes, helping crops establish well, grow consistently and maintain performance through changing seasonal conditions.
Rather than replacing good crop management, Seaweed Plus complements existing nutrition and agronomic programmes by supporting healthy plant development from establishment through to harvest.

Seaweed Plus – Build Root Strength, Stress Resilience, and Nutrient Efficiency
Seaweed Plus is a high-concentration, New Zealand-made seaweed extract that goes beyond traditional plant tonics. Designed for commercial growers, it supports root development, stress tolerance, and nutrient efficiency while improving soil biological activity.
The Problem: Limited Impact of Standard Seaweed Products
Many seaweed products on the market are primarily foliar stimulants. While they can improve plant appearance temporarily, they do not consistently enhance root growth, stress resilience, or soil function, limiting their long-term agronomic impact.
The Solution: Seaweed Plus
Seaweed Plus combines premium Ascophyllum nodosum extract with humic and fulvic acids to deliver a dual-action system that works at the soil–root–plant interface:
Seaweed bioactives (auxins, cytokinins, betaines) support plant stress response, balanced growth, and recovery.
Humic and fulvic acids enhance nutrient availability, stimulate root development, and support soil microbial activity.
This combination addresses both plant performance and soil function, providing measurable benefits beyond a simple foliar tonic.
Observed Benefits
Field observations and grower experience across New Zealand indicate that Seaweed Plus:
Improves stress resilience – helps crops manage heat, cold, transplant, and moisture stress
Enhances root growth – stronger roots for better water and nutrient uptake
Supports nutrient efficiency – humic and fulvic acids mobilise soil nutrients and improve fertiliser uptake
Delivers commercial-grade performance – concentrated formula with low use rates suitable for orchards, vineyards, row crops, and intensive horticulture
Note: Effectiveness depends on crop species, soil type, environmental conditions, and overall nutrient management.
How to Use
Apply as a foliar spray or soil application
Compatible with most fertilisers and crop protection products (perform a jar test before tank mixing)
Integrates seamlessly into existing crop nutrition programs
Typical application rates vary depending on crop, soil, and growth stage
Suitable For
