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

Benefits of Sea-Prime

    Supports vital growth, resilience, and recovery during the growing season.
  • For leaves & root zone
    Use around the roots as the standard method, or as a foliar feed for quick extra support.
  • Broadly applicable
    For houseplants, garden plants, vegetable gardens, lawns, and fruiting crops.
  • Rich in plant-based building blocks
    With seaweed extract, amino acids, humic acids, and fulvic acids for extra support.
  • Easy to combine
    Use Sea-Prime alongside Houseplant Formula, Garden Formula, or Tomato & Chile Formula.

What’s inside

  • Seaweed extract
    Ascophyllum nodosum supports vital growth and resilience.
  • Amino acids
    Plant-based building blocks for efficient uptake and healthy development.
  • Humic and fulvic acids
    Support nutrient availability around the roots.
  • Minerals and trace elements
    Enriched with carefully selected minerals for extra support during the growing season.

How to use

  • Mix: shake the bottle well and mix 2–10 ml Sea-Prime per 1 liter of water.
  • Around the roots: use this as the standard method for regular support alongside your base fertiliser. Pour the solution directly around the root zone.
  • Foliar feeding: use for quick extra support during active growth, recovery, or stress moments. Mist finely over the leaves, preferably early in the morning or later in the day.
  • Choose one method: you can apply Sea-Prime around the roots or use it as a foliar feed. You do not need to use both methods at the same time.
  • Combine: alternate with your Garden Gold base fertiliser during the growing season.
