Collection: Premium Organic Fertilisers

Two ways to feed a garden

The whole range in one place: finished crop blends alongside the single-ingredient fertilisers and minerals the blends are built from. Pick a blend and let one bag cover a crop for the season, or pick the individual nutrients and build the programme yourself.

The crop blends

Each one is tuned to how a single crop actually feeds across a season, not to a generic NPK ratio. All are hand-blended in small batches in Stockport and packed in compostable paper.

• Tomato Fertiliser 3-4-6: high potassium with calcium, for fruit set, flavour and resistance to blossom end rot.
• Rose Fertiliser 5-3-5: built around repeat flowering, depth of colour and fragrance.
• Chilli & Pepper Fertiliser: aimed at flavour, aroma and heat, not just fruit count.
• Strawberry Fertiliser: high potash to support sugars and aroma in the fruit.
• Potato Fertiliser: slow-release feeding across tuber bulking.
• Fruit & Vegetable Fertiliser 4-5-6: one bag for a mixed bed or allotment.
• All Purpose 4-4-4: balanced, for veg, flowers, shrubs and trees.
• Bloom 2-8-4: high phosphorus, for the flowering and fruiting stage.
• Lawn Fertiliser 10-3-3.5: high nitrogen for grass, gentle enough not to scorch.

The single ingredients

The same inputs used in the blends, offered straight, for correcting one thing at a time.

• Potassium and multi-minerals: Yorkshire polyhalite supplies potassium, calcium, magnesium and sulphur in a single granule; sulphate of potash is chloride-free 50% K₂O. If you are choosing between them, this guide walks through when each one is the right call. Also micronised potassium for fast correction.
• Phosphorus: micronised rock phosphate at 31% P and 46% Ca for slow-release phosphorus and calcium, and PK with calcium and micronutrients for the fruiting stage.
• Nitrogen: 13% N granular for leafy growth and alfalfa meal pellets, which are organically grown and carry triacontanol alongside their nitrogen. Why that matters: the organic fertiliser with a built-in growth hormone.
• Calcium and magnesium: amino-chelated calcium for fast uptake, kieserite at 25% Mg, and granulated gypsum for calcium and sulphur without a pH shift.
• Biostimulant: soluble seaweed extract, which layers on top of any of the above.

What runs through all of it

• Slow release, no spikes. Granular feeds break down gradually across the season. No surge, no root burn, no salt building up in the pot.
• It feeds the soil as well as the plant. Organic ingredients give the bacteria, fungi and worms something to work on, which is what builds fertility that lasts past this season.
• Every ingredient named. No "organic base" hiding on the label.
• Compostable packaging on every blend.
• Safe around children, pets, bees and birds. No synthetic chemicals.

Where to use it

Pots, grow bags, raised beds, allotments, no-dig beds and living soil. Rates and frequencies are on each product page. New to organic feeding? Start here. Working out quantities for liquid feeds? Use the liquid fertiliser calculator.

Common questions

Blend or single ingredient: which should I buy?

A blend if you want one bag to cover a crop for the season. Single ingredients if you have a specific deficiency to fix, or you are building your own programme and want to control each element. If you are unsure, start with a blend.

Can I use these in pots and grow bags?

Yes, all of it. Pots, grow bags, raised beds, allotments and open ground.

How is this different from a supermarket organic feed?

Two things. The blends are multi-input, so a single bag carries N, P and K plus calcium, magnesium, sulphur and a full trace element set, rather than NPK alone. And every ingredient is named on the label. For a worked comparison against the feeds most people already own, see five UK tomato feeds compared.

Are they safe around children, pets and bees?

Yes. Made with organic ingredients, with no synthetic chemicals, plant protection products or harmful additives.

How long does a bag last?

It depends on the crop and the area, and the rate is on each product page. As a rough guide, a 1.5kg bag of a crop blend covers a season for a small greenhouse or a raised bed.
