Looking for an organic seaweed booster to use alongside your plant fertiliser? Garden Gold Sea-Prime is a concentrated liquid seaweed formula for application around the roots or as a foliar spray — with 24% seaweed extract, 20% amino acids, and fulvic acids.

Benefits of Sea-Prime

  • Concentrated seaweed support
    Contains 24% seaweed extract to support vital growth and plant resilience.
  • For leaves and the root zone
    Apply around the roots for regular support or use as a foliar spray when you want faster extra support.
  • Broadly applicable
    Suitable for houseplants, garden plants, vegetable gardens, lawns, and fruiting crops.
  • Rich in plant-based building blocks
    Contains 20% amino acids together with seaweed extract and fulvic acids.
  • Easy to combine
    Use Sea-Prime alternately with Houseplant Formula, Garden Formula, or Tomato & Chile Formula.

What’s inside

  • Seaweed extract
    Contains 24% Ascophyllum nodosum seaweed extract to support vital growth and resilience.
  • Amino acids
    Contains 20% amino acids: plant-based building blocks that support healthy plant development.
  • Fulvic acids
    Support nutrient availability and uptake.
  • Minerals and trace elements
    Enriched with carefully selected minerals for extra support during active growth.

How to use

  • Mix
    Shake the bottle well and always dilute Sea-Prime with water. Use 5–10 ml per 1 liter of water around the roots or 2–5 ml per 1 liter of water as a foliar spray.
  • Apply around the roots
    For regular support, apply the diluted solution directly around the root zone, preferably onto slightly moist soil.
  • Apply as a foliar spray
    Spray the leaves lightly and evenly, preferably early in the morning or later in the day and never in full sun. Spray both sides of the leaves, paying particular attention to the undersides.
  • Choose the application method
    Use Sea-Prime most often through watering for regular support. Foliar application is useful when you want faster extra support during active growth, recovery, or challenging growing conditions.
  • Combine
    Alternate Sea-Prime with your Garden Gold base fertiliser: use the base fertiliser for one feeding and Sea-Prime for the next. You do not need to use both products during the same feeding.
