FAQs:
What is Ocean Grown Fish & Kelp Compost?
A premium, screened compost boosted with fully composted kelp (seaweed) and fish. It’s designed to feed soil life, add trace minerals, and steadily improve structure for healthier, faster-growing plants.
What exactly is in the bag?
An airy compost base enriched with about 500 g of fully composted kelp and 150 g of fish material per bag, plus all the beneficial biology and humus you expect from quality compost.
How do I use Ocean Grown Fish & Kelp Compost?
Top-dress a 1 cm layer over your soil, water in well. Repeat monthly for ongoing results. You can also blend it into mixes or brew into a (well-aerated, filtered) compost tea for soil drenches.
How much area does one 15 L bag cover?
At a 1 cm top-dress, roughly 1.5 m². If you go thinner as a light dusting, it’ll go further; thicker for heavy feeders will cover less.
How much should I use for pots?
As a guide for a 1 cm top-dress:
• 20 cm pot ≈ ⅓ L
• 30 cm pot ≈ 0.7 L
• 40 cm pot ≈ 1.25 L
Spread evenly and water in.
How often should I reapply?
Monthly during active growth. For maintenance beds or over winter, every 6–8 weeks is fine.
Can I mix Ocean Grown Fish & Kelp Compost into potting soil?
Yep. Blend 10–20% by volume into fresh mixes for a gentle, biological boost. For established pots, stick to top-dressing.
Is Ocean Grown Fish & Kelp Compost safe for edible gardens?
Absolutely. It’s made from natural inputs (composted seaweed and fish) and is ideal for veggies, herbs, berries, and fruit trees.
Will Ocean Grown Fish & Kelp Compost make the garden smell fishy or attract pests?
It has a mild “ocean/earthy” note out of the bag, but once watered in (and especially if you cover with mulch) the smell drops fast. To avoid pets digging, water thoroughly and cover with 2–5 cm of mulch.
What about Australian natives and P-sensitive plants?
It’s a compost-based soil conditioner, not a high-P synthetic fertiliser, so it’s generally fine used as a light top-dress. Start with a thinner layer (5 mm) and monitor.
Is there salt in seaweed compost? Will it harm plants?
The kelp is fully composted, which greatly reduces raw salt concerns. Used at label rates and watered in, it’s safe—even for containers. Don’t pile it thick against tender stems, and avoid repeated heavy applications without flushing.
What benefits should I expect to see?
Better soil structure, improved water-holding, more worms/microbes, stronger root growth, bigger blooms, and better flavour/quality in produce over time.
Can I use Ocean Grown Fish & Kelp Compost on lawns?
Yes. Rake or brush in a thin 5–10 mm layer and water deeply. It’s a simple way to green up and improve soil under turf.
Does Ocean Grown Fish & Kelp Compost replace fertiliser?
Think of it as the engine-builder for your soil. It feeds biology and adds slow minerals. For heavy feeders, pair it with your regular organic fertiliser or Ocean Grown liquids.
Can I brew a compost tea with Ocean Grown Fish & Kelp Compost?
You can. Use an aerated setup, add a small handful per 10 L, and filter before applying to avoid clogging. Teas are for soil and foliage; don’t put solids or tea into hydro systems.
Is Ocean Grown Fish & Kelp Compost suitable for indoor plants?
Yep—great for aroids and houseplants. Apply a thin top-dress (5–10 mm), water in, and wipe any residue off the rim. Odour is minimal once watered.
Good for seedlings?
Seedlings prefer a gentle start. Use your seed-raising mix as normal; begin top-dressing very lightly once true leaves appear.
What’s the pH and NPK?
Compost isn’t sold on NPK like salts are. Expect a neutral-leaning, biology-rich amendment with a broad spread of trace elements and organic nitrogen—designed to build living soil rather than spike numbers.
Is Ocean Grown Fish & Kelp Compost certified organic?
Inputs are natural (composted kelp and fish). Certification isn’t stated for this product; if you require a specific cert, treat it as “not certified” for compliance paperwork.
Will Ocean Grown Fish & Kelp Compost burn plants?
Not at recommended rates. Always water in after applying and avoid mounding against stems/crowns.
Is Ocean Grown Fish & Kelp Compost safe around pets and kids?
It’s non-toxic, but dogs may be very interested (fish!). Store securely, apply, water in, and mulch to discourage digging. As always, supervise kids in the garden.
Can I use Ocean Grown Fish & Kelp Compost in hydroponics or recirculating systems?
No. It’s a particulate organic compost—great for soil and soilless mixes, not for hydro lines or emitters.
Does Ocean Grown Fish & Kelp Compost contain weed seeds or pathogens?
It’s a fully composted, screened product. Proper composting and screening greatly reduce weed seeds and pathogens compared with raw organics.
Any plants I shouldn’t use Ocean Grown Fish & Kelp Compost on?
Avoid smothering very fine-rooted alpines or ultra-sensitive xeric cacti. For salt-sensitive ornamentals, start light and water well.
How should I store Ocean Grown Fish & Kelp Compost?
Keep sealed, cool, and dry, out of sun. Use within 6–12 months for best biology.
What does a 30 L bag cover?
About 3 m² at a 1 cm layer.
Can I apply Ocean Grown Fish & Kelp Compost before mulching?
That’s the move. Top-dress compost first, water, then mulch. The compost feeds from above; the mulch keeps moisture and microbes humming.
Can I combine Ocean Grown Fish & Kelp Compost with other Ocean Grown products?
Yes—common combos are Fish Hydrolysate (liquid) for quick biology and Deep Sea Sugar & Kelp for root vigor. Use liquids lightly and let the compost do the heavy lifting.
What results have customers reported?
Quicker growth, happier houseplants, better yields, and more “life” in tired soils—plus easy handling thanks to the screened texture.
Quick application cheat-sheet
• Beds: 1 cm monthly, water in
• Veggie starts: 5 mm after true leaves, then monthly
• Pots: 1 cm every 4–6 weeks
• Lawns: 5–10 mm, brush in, deep water
Anything else to know?
Water is your friend. A good soak after top-dressing switches on the microbes and knocks down any smell. Cover with mulch for best, longer-lasting impact.
