Restorative power
For generations, planting trees has been a powerful symbol of environmental action, a tangible step towards a healthier planet. At SeaGrown, we invite you to look beneath the waves and embrace an equally vital solution: Plant a Tree in the Sea.
This unique programme leverages the incredible restorative power of seaweed cultivation to directly combat the Triple Planetary Crisis – climate change, pollution, and biodiversity loss – right here in our oceans, offering you a novel and impactful way to achieve your sustainability goals.
Underwater forests
Our "Sea Trees" form thriving underwater forests of native kelp, cultivated using our innovative Kelpedo™ system. Developed and proven on the Yorkshire coast, each Kelpedo™ unit is designed to establish and nurture vital marine ecosystems in the sea. It’s our cutting-edge technology - developed right here in Yorkshire - that turns the concept of large-scale ocean restoration into a measurable reality, providing the basis for nature to flourish.
Partnership
Partnering with SeaGrown through "Plant a Tree in the Sea" provides a credible, transparent, and impactful way for you to demonstrate your commitment to Environmental, Social, and Governance (ESG) principles. Investing in Kelpedo™ units directly supports carbon sequestration, enhances marine biodiversity by creating crucial habitats, and improves water quality by absorbing excess nutrients. It's a powerful investment in an exciting new nature-based solution and a clear statement of forward-thinking corporate responsibility, contributing directly to a healthier ocean and planet.

Why seaweed?
Seaweed delivers benefits to our oceans - but how?
-
Seaweed thrives using only natural seawater and sunlight. Unlike land-based initiatives, it requires no land, no freshwater, and no chemicals to grow, making it a truly sustainable choice.
-
Kelp forests are biodiversity hotspots. Our seaweed creates complex underwater habitats, providing new food sources and essential shelter for a wide array of marine species, significantly boosting local biodiversity and contributing to more life in our seas.
-
Seaweed acts as a powerful natural way to clean the seas. It actively absorbs excess nutrients (like nitrogen and phosphorus runoff from land), helping to combat coastal pollution, oxygenate the water, and improve overall marine water quality.
-
Seaweed is very fast-growing. This means our seaweed establishes effective habitats quickly and start delivering positive environmental impacts, like carbon sequestration, rapidly and efficiently, year-round.
-
Supporting seaweed cultivation benefits coastal communities. It creates new green jobs, offers educational outreach opportunities, and provides sustainable diversification pathways for traditional fishing and other maritime industries.
