Liquid Seaweed Fertiliser – 1L Concentrate, Makes Up To 500L of Plant Feed with Built-In Hose Spray

A natural seaweed biostimulant that does more than feed — it strengthens roots, boosts leaf and flower growth, and increases fruit and veg yields, while feeding the soil life that keeps your plants healthy all season. Cold-pressed from sustainably sourced Ascophyllum nodosum seaweed and enriched with humic and fulvic acids, amino acids and natural plant sugars.

Why gardeners love it:

• Stronger roots, bigger yields – seaweed biostimulants improve rooting, flowering and fruit set across veg, flowers and shrubs
• More than just seaweed – added humic & fulvic acids and amino acids feed beneficial soil microbes for steadier nutrition and healthier soil
• Made for peat-free compost – refined to improve moisture retention and nutrient uptake in modern peat-free mixes, where ordinary feeds fall short
• One feed for everything – clear dilution rates on the bottle for fruit & veg, flowers & shrubs, house plants and lawns
• Exceptional value – one concentrated 1L bottle makes up to 500L of feed; a season of feeding for pennies per watering can
• Sustainable – responsibly sourced seaweed, made in Britain, 100% recycled bottle

Why seaweed?

Seaweed has been used by generations of growers for a reason: it's packed with natural growth compounds, trace elements and minerals that synthetic feeds don't provide. Cold pressing (rather than heat extraction) preserves these delicate compounds, so more of the good stuff reaches your plants. The result is stronger, more resilient growth — plants that cope better with heat, drought and transplant shock.

Why it suits peat-free compost

Peat-free composts behave differently — they dry out faster and hold nutrients differently to peat. This feed is specially refined for peat-free growing, improving moisture retention and helping plants access nutrients efficiently. If your results in peat-free compost have been disappointing, the feed is often the missing piece.

Frequently asked questions

Is it safe for edible crops?
Yes — a natural feed ideal for fruit, vegetables and herbs. Suitable for use right through the cropping season.

How much do I use?
Dilution rates for each plant type are on the bottle — measured with the 10ml cap. One 1L bottle makes up to 500L of diluted feed.

Can I use it on house plants?
Yes — there's a gentle house plant dilution rate. It's excellent for reviving tired indoor plants.

Is it a complete fertiliser?
It's a biostimulant feed — it supplies natural nutrients and growth compounds while improving how plants take up feed from the soil. For heavy-fruiting crops like tomatoes, it works brilliantly alongside your usual routine or on its own for general feeding.

When should I feed?
Every 1–2 weeks from spring to autumn. Foliar spraying in the morning or evening gives the fastest visible response.
