Envii Allgrow Organic Multipurpose Liquid Fertiliser – 1 Litre

Allgrow is a certified organic liquid fertiliser from Envii that works across the board — whether you're feeding tomatoes in the greenhouse, roses in the border, or houseplants on the windowsill. Its balanced NPK ratio of 6-2-4 delivers a steady supply of nitrogen, phosphorus, and potassium, giving plants what they need to grow strongly, produce well, and stay healthy throughout the season. Because it's made entirely from natural and mineral-based ingredients, it's safe to use around children, pets, bees, and other garden wildlife without any hesitation.

The concentrate is seriously economical — a single one-litre bottle makes up to 330 litres of feed once diluted, so it goes a very long way. Mixing it couldn't be simpler either. The bottle comes with a built-in measuring chamber, so you just fill it to the 15ml mark, add that to five litres of water, and apply it to the base of your plants. No guesswork, no fuss.

This is a particularly good choice for gardeners who want an all-in-one feed they can use confidently on everything without needing a shelf full of specialist products. The organic certification also makes it ideal for anyone growing edibles who'd rather keep things as natural as possible, and the year-round suitability means it earns its place in the shed no matter what the calendar says.
