Best berry fertiliser UK: top pick and best value

Updated: October 2026

Best berry fertiliser UK on a search page is usually a US list, a high-street bottle that is not in this set, or a yield claim nobody here has measured. This page names a top pick and a best value from the eight amazon.co.uk listings in the [berry fertiliser comparison](/hub/fertiliser-soil-and-bark-mulch/berry-fertiliser), then says who should skip each one. There is no laboratory ranking and no best-in-Britain medal. Stars, counts and GBP prices are the amazon.co.uk lines. We did not test these packs and we did not measure fruit. A qualifying purchase through our links can earn a commission at no extra cost to you.

What best can mean here

A star line is a listing statistic, not a formula score. UK GROW's 1 L fruiting liquid sits at 4.8 from 11 reviews, the highest score in this set. Jobe's fruit-and-nut bag sits at 4.6 from 477, but in the Amazon reviews the texts are almost all United States. Hortulani and Cultivers sit at 4.0. Substral Naturen and Neudorff Azet have no star line on the listing, so their scores stay 0. Those numbers tell you how many shoppers left a rating, not which bag grew a heavier punnet. Hortulani is about £7.98 and the 1 L UK GROW is about £10.99. Dearer parcels in the set are more kilos, more litres, or an import. Crop and the label come first on the berry fertiliser buying guide.

Picks from the eight listings

The top pick in this set is UK GROW fruiting plants, 1 L, at about £10.99. According to the product data the bullets name fruit plants including berries, apples and tropical fruits. In the Amazon reviews people call it easy to mix, and one United Kingdom text describes a monthly feed. Citrus is asked on the listing and not answered. The best value is Hortulani microbiological strawberry plant food, 500 g, at about £7.98. It is the cheapest pack that already has a star line. According to the product data the job is a soil improver you mix in at 500 g per 50 m², and the listing prints no NPK. In the Amazon reviews a United Kingdom text says there are no English instructions on the packet. If you wanted a strawberry-labelled liquid instead of a soil improver, UK GROW strawberry 500 ml is the next bottle, at about £9.99. According to the product data it names pots, hanging baskets and greenhouses, and it prints no NPK. The 5 L at about £24.99 shares that 4.3 from 15 line. It is bulk for many plants, not a stronger formula.

Weak fits and the missing aisle

Azet 1 kg at about £11.28 prints organic 7-3-10 and names berry bushes, strawberries, wine, fruit shrubs and trees. The listing brand is the shop name, not Neudorff, and there is no star line. Naturen 1.2 kg at about £19.43 names a similar crop list, claims up to three months, and states no animal ingredients, with no NPK on this listing. That is an ingredient fork, not a winner we measured. Jobe's at about £49.12 has United States reviews in the Amazon sample, a mixing field of 4:6:6 against a review that cites 3-5-5, and notes of smell and split bags. Cultivers at about £15.58 prints 8-1-5 and does not name berries. The only written review is from Spain and alleges short weight. None of these eight is a blueberry fertiliser. Tomato feed is a different argument, on berry fertiliser or tomato feed.

Which pick matches the job

If the shed already has Vitax Organic Strawberry Feed, that high-street bottle is not scored here. If you wanted a printed 7-3-10 granule, Azet is the pack that prints it on the listing. If you wanted the cheapest reviewed sticker and will accept a soil improver, Hortulani is the best-value line. If you wanted a 1 L fruiting liquid with a star line, UK GROW 1 L is the top pick in this set.

Common questions

Why is Vitax not in the table?
Vitax Organic Strawberry Feed is the usual high-street bottle on the UK search page. It was not in this amazon.co.uk set, so it is not scored. We name it so you do not think this eight-pack set beat the bottle you already see in garden centres.
Is Azet better than Naturen?
Not as a result we measured. Azet prints 7-3-10 and uses animal by-products. Naturen names a berry-and-fruit list, claims up to three months, states no animal ingredients, and prints no NPK on this listing. Neither has a star line. Choose on label and ingredients, not on a medal.
Is the 5 L UK GROW strawberry bottle worth it?
It is the cheap bulk liquid per litre at about £24.99 if you already run many strawberry plants and accept an unprinted NPK. It shares its 4.3 from 15 line and its written review with the 500 ml. It is not a stronger formula. Two hanging baskets do not need five litres.
Should you buy Jobe's at about £49?
Not as a UK default. The 4 lb bag is about £49.12, the reviews in the listing file are United States, and the NPK field conflicts with a review. Smell and split bags appear in that sample. Buy it only if you already use that US fruit-and-nut product and accept the import price.
Which one is for blueberries?
None of these eight. Blueberries need ericaceous compost, rainwater and a modest acid feed. A general berry bag, a strawberry liquid and tomato feed are the wrong aisle. Do not treat Azet's berries line as a blueberry recommendation.
