envii SeaFeed Xtra Organic Seaweed Liquid Fertiliser – 1L

envii SeaFeed Xtra is a concentrated liquid seaweed fertiliser that gives your plants a natural, nutrient-packed boost from root to tip. Made from sustainably sourced seaweed and enriched with iron and plant-based amino acids, it encourages strong growth, lush foliage, and improved root development across everything from lawns and vegetables to houseplants and flowering borders. It's certified organic by OF&G, so it's a straightforward choice for gardeners who prefer to keep things natural and vegan-friendly.

One of the more practical things about SeaFeed Xtra is just how far a single bottle goes. One litre dilutes to make up to 500 litres of feed, which means it suits gardens of all sizes without the constant need to restock. The bottle itself comes with a built-in measuring chamber, which takes the guesswork out of mixing and makes it easy to get the dilution right every time — handy whether you're feeding a few pots on the patio or treating a large vegetable plot.

This is a genuinely versatile feed that works equally well indoors and out, making it a useful all-rounder to keep in the shed throughout the growing season. Whether you're trying to improve a tired lawn, boost fruit and vegetable yields, or simply keep your houseplants looking their best, SeaFeed Xtra offers a gentle but effective way to support plant health without resorting to synthetic chemicals.
