Seaweed Fertiliser for Plants – Organic Liquid Feed for Indoor & Outdoor Use – Cold Pressed with Humic, Amino & Fulvic Acids

Give your plants the feed they actually deserve. 

HouseProud Organic Seaweed Fertiliser is a concentrated liquid plant food made from cold-pressed seaweed, enhanced with humic and fulvic acids to deliver stronger roots, greener leaves, and improved flowering and yields across your entire garden.

Unlike heat-treated or chemically extracted seaweed feeds, our cold-press process retains the natural bioactive compounds — including plant hormones, micronutrients, and growth stimulants — that drive real, visible results. The addition of humic and fulvic acids boosts nutrient uptake and water retention at root level, making this fertiliser particularly effective when used with peat-free composts.

What You'll See

Greener, healthier foliage. Stronger root development. More abundant flowering and improved fruit and vegetable yields. Plants that are better equipped to handle environmental stress and seasonal change. Whether you're feeding a vegetable patch, flower borders, hanging baskets, houseplants, or your lawn — this one bottle covers the lot.

What's in It

Cold-pressed seaweed extract provides a naturally rich source of micronutrients, plant hormones, and bioactive compounds. Humic acid improves soil structure and helps nutrients stay available to plant roots for longer. Fulvic acid enhances nutrient absorption and supports water retention — a real advantage in peat-free growing media where moisture management matters most.

Suitable For

Vegetables, fruit, flowers, lawns, houseplants, hanging baskets, containers, and ornamentals. Safe to use year-round.

Sustainably Made

The seaweed in this product is sustainably sourced, and the bottle is made from 100% recycled packaging. Manufactured in the UK by Qualkem — over 50 years of chemical manufacturing expertise.
