Rescue Remedy: The Ultimate Seaweed Fertiliser for Thriving Plants

Rescue Remedy is arguably Australia’s highest-analysis seaweed fertiliser, formulated from Ascophyllum nodosum in a fully soluble powder or flake form. Designed for easy foliar application, irrigation, or fertigation, this premium seaweed bio-stimulant promotes healthy roots, stronger plants, improved flowering, and increased fruit and vegetable yields. With natural plant hormones, trace elements, amino acids, and complex carbohydrates, Rescue Remedy revitalises stressed plants, boosts beneficial soil microbes, and helps plants thrive in both gardens and commercial cropping systems.

Why Choose Rescue Remedy?

  • Promotes root growth and improves nutrient uptake
  • Boosts microbial activity in soil for healthier plant ecosystems
  • Increases frost and stress tolerance
  • Enhances flowering, fruit set, and overall plant vigour
  • Raises Brix levels for sweeter, healthier produce
  • Versatile application: foliar spray, fertigation, or irrigation
  • Sustainable, high-analysis seaweed solution

 

Who it's for and how to use it: 

Lawns (Buffalo, Couch, Kikuyu & More)

  • Supports root development and green, healthy turf
  • Foliar or irrigation application for ongoing maintenance
  • Apply 10g per 10L water or 10g per 100sqm fortnightly, or as required
  • Helps turf recover from drought, frost, or waterlogging

  • Improves plant resilience during transplanting, heat, or drought stress
  • Foliar spray: 100g per 100L water (vegetables and ornamentals)
  • Fertigation: 1kg/ha every 1–2 weeks until flowering
  • Orchards & vineyards: Foliar 100g/100L water, fertigation 1kg/ha twice before flowering

Rescue Remedy is ideal for revitalising plants stressed by drought, heat, frost, or waterlogging, while also enhancing blooms, fruit set, produce quality, Brix levels, and stimulating beneficial soil microbes.

The Science Behind Rescue Remedy

Rescue Remedy harnesses the power of Ascophyllum nodosum seaweed, a natural bioactive ingredient packed with compounds that actively support plant growth, stress resilience, and overall health.

  • Natural Hormones (Auxins, Cytokinins, Gibberellins): These naturally occurring plant hormones stimulate root development, promote stronger flowering, and enhance fruit set, helping plants reach their full growth potential. 
  • Complex Carbohydrates: These polysaccharides act as a food source for beneficial soil microbes, improving soil biology, nutrient cycling, and overall plant health. 
  • Frost Protection: Certain compounds in the seaweed provide natural anti-freeze properties, reducing cellular damage and helping plants survive low-temperature events. 
  • Stress Resilience: Bioactive components boost plant tolerance to environmental stresses, including drought, heat, waterlogging, and transplant shock, enabling more consistent growth under challenging conditions.
  • Brix Enhancement: Seaweed-derived compounds increase sugar accumulation in fruits and vegetables, improving taste, nutritional quality, and shelf life.
  • Chelating Trace Elements: Natural chelators bind essential micronutrients, making them more available for plant uptake and enhancing overall nutrient efficiency.

Together, these mechanisms make Rescue Remedy an all-in-one solution for supporting plant vitality, maximising yield, and improving the quality of fruits, vegetables, and ornamentals, even in less-than-ideal growing conditions.
