Ocean's Bounty Organic Seaweed Fertilizer — 16 fl oz Concentrated Liquid
Most fertilizers are made in factories. Ours is made in the ocean.
Ocean's Bounty is a concentrated liquid seaweed extract, cold-pressed from tropical red and brown seaweeds sustainably farmed and harvested by coastal village women along the southern coast of India. Every bottle is OMRI certified organic, meaning no synthetic chemicals — ever.
Unlike synthetic fertilizers that feed your plants and nothing else, seaweed extract works with your soil. The natural plant hormones — auxins, cytokinins, and gibberellins — stimulate deeper root development, stronger stems, and greener leaves. The trace minerals and amino acids improve how your soil holds nutrients over time.
One 16 oz bottle makes up to 75 gallons of ready-to-use fertilizer. That's enough to treat a full backyard garden for an entire growing season.
Why Seaweed?
Unlike synthetic fertilizers, seaweed extract works with your soil — not just your plants.
- Stimulates deeper roots and stronger stems from the first application
- Greener, fuller leaves — naturally, without nitrogen burn risk
- Improves soil structure and microbial activity over time
- Safe for all plants: vegetables, fruits, herbs, houseplants, lawn & turf
- OMRI Listed Organic — approved for certified organic growing
- Highly concentrated: just 2–4 tsp per gallon goes a long way
How To Use
- Shake well before each use
- Mix 2–4 teaspoons per gallon of water
- Apply as foliar spray or soil drench every 1–2 weeks
Tip: Apply early morning or evening for best results

Is this safe for edible plants — vegetables and herbs?
Yes. Ocean's Bounty is OMRI Listed Organic and safe for all edible plants. You can apply it right up to harvest.
How is this different from regular fertilizer?
Most fertilizers supply nutrients directly. Seaweed extract works differently — it stimulates your plant's own growth mechanisms and improves the soil's ability to hold and deliver nutrients. Think of it as a supplement, not just plant food.
How long does one bottle last?
At 2–4 tsp per gallon, one 16 oz bottle makes 38–75 gallons of ready-to-use solution. For a typical home garden applied every two weeks, that's a full growing season.
What does 0-0-8 mean on the label?
That's the NPK ratio — nitrogen, phosphorus, potassium. Our formula is potassium-forward (8% soluble potash), which supports stress tolerance, root strength, and fruit quality. The natural plant hormones in seaweed do the heavy lifting on growth.
Where is this made?
The seaweed is farmed and cold-pressed into extract in South India, then bottled and shipped to the US. Ocean's Bounty is a family-owned American business based in St. Petersburg, Florida.

Love this stuff. It's natural and coming from someone with an anti green thumb, it's been helping a lot!
My parents have been using Ocean’s Bounty on their trees and the results have been awesome! They got SO much fruit this year — we were genuinely blown away. The soil feels healthier, the trees are thriving, and I love knowing we’re using something organic. Even better, it feels good supporting a company whose mission helps empower women in India. Great product with an even better purpose! — Cade
P.S. we grew so much kiwi this year I started selling it on the side. Hit me up.
