Let your garden drink in the ancient strength of the sea. SeaFeed Xtra is a highly concentrated organic liquid fertiliser made from sustainably harvested Ascophyllum nodosum seaweed straight from the Atlantic coast. It’s packed with essential plant nutrients like nitrogen, potassium and magnesium, trace elements such as iron and zinc, plus plant-based amino acids that help plants resist stress and thrive through change.

Designed to be used as both a foliar spray and root feed, this seaweed elixir improves soil structure and encourages vigorous root growth, deeper colour and blooming energy in everything from lawn and shrubs to vegetables and fruit trees.

How to use: Follow the bottle’s dosage guide - apply every 7 days during the growing season and up to every 14 days on lawns. One litre will make up to 500 L of feed, making this both effective and great value.

One customer said they’d used Envii’s seaweed fertiliser for years and “it makes a real difference to my crops - I swear by it.”
