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

Extra seaweed boost
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 always dilute Sea-Prime with water. Use 5–10 ml per 1 litre of water around the roots or 2–5 ml per 1 litre of water as a foliar spray.
Around the roots
The easiest choice for regular support. Apply the diluted solution through watering directly around the root zone.
Foliar spray
Spray a light, even mist over the leaves, preferably early in the morning or later in the day and not in full sun. Spray the underside of the leaves as well.
Use through roots or leaves?
For regular support, use Sea-Prime most often through watering around the roots. As a foliar spray, Sea-Prime is useful when you want faster extra support during active growth, recovery or stress moments.
Combine
Alternate Sea-Prime with your Garden Gold base fertiliser: one feeding with the base fertiliser, the next feeding with Sea-Prime.

DOSAGE

Dosage for Sea-Prime

5 ml = 1 teaspoon

10 ml = approximately 2 teaspoons

Use through roots or leaves?

Around the roots
5–10 ml per 1 litre of water
The easiest choice for regular support. Use through watering around the root zone, for example as an alternating feed with your Garden Gold base fertiliser.
Foliar spray
2–5 ml per 1 litre of water
Useful when you want faster extra support during active growth, recovery or stress moments. Apply a light, even mist, preferably including the underside of the leaves.
Young or sensitive plants
Start low within the dosage range
Begin with 5 ml per litre around the roots or 2 ml per litre as a foliar spray, and increase only when the plant responds well.

For regular use, Sea-Prime through watering around the roots is the simplest choice. Foliar spray is especially useful when you want faster extra support during active growth, recovery or stress moments. You do not need to use both applications every time.

How often to use

Use Sea-Prime during the active growing season, usually once every 1–2 weeks. In winter, or during a clear resting period, use less often or apply a lighter dose.

Using as a foliar spray

Spray preferably early in the morning or later in the day and not in full sun. Mist the leaves lightly and evenly, preferably including the underside of the leaves.

Do not use Sea-Prime as a foliar spray on fully wet leaves, in strong sun, high heat or shortly before rain.

Combining with base fertiliser

Want to combine Sea-Prime with Houseplant Formula, Garden Formula or Tomato & Chile Formula? Use the alternating rhythm: one feeding with your base fertiliser, the next feeding with Sea-Prime, then back to your base fertiliser.

You do not need to use Sea-Prime together with your base fertiliser in the same watering.

Important

Always dilute with water before use.
Shake the bottle well before use.
Use the mixed solution preferably on the same day.
Always start with a low dose for sensitive plants.
Do not spray in full sun, high heat or shortly before rain.
Store cool, dark and frost-free between 5°C and 30°C.
Natural sediment may occur; this is normal for products made from natural raw materials.
