Top pick: Miracle-Gro Performance Organics Fruit & Veg, 1 kg
We name this our top pick because it is the only granule here whose amazon.co.uk listing gives the item type as a fruit and veg food, with fruit and vegetables as the target species. Reviewers describe cropping on tomatoes, cucumbers, aubergines and strawberries. The manufacturer's UK page, outside the listing, gives NPK 8-5-5 and a rate of 75 to 100 g per square metre for medium-demand crops.
Several reviews describe a strong smell that fades after a day or a watering-in, and two reviewers found blue mould where granules were left on the soil surface, so work the feed into the soil. At 75 to 125 g per square metre, 1 kg is about 60p to £1.00 per square metre. That is arithmetic on the listing price and the manufacturer's rates, not a test result.
Best value for a large plot: Westland Growmore, 8 kg
If you are feeding a big plot, cost per square metre changes the answer. Westland Growmore 8 kg costs £16.95, about £2.12 per kg. Reviewers praise the easy spreading and the sturdy tub.
Three limits apply. The listing bullets do not name vegetables, and many reviewers fed lawns or flowers, so the vegetable evidence in the reviews is thin. Several reviews report tubs that split or lids that popped off in transit, with product spilled. The listing gives no NPK figure, so check the rate on your own pack. If you want a Growmore-type tub whose listing names vegetables, the Growmore for vegetables page compares it with the Topline 8 kg tub at £23.99, about £3.00 per kg.
When a liquid, slow-release or soluble listing wins
The other four listings suit narrower jobs. Miracle-Gro All Purpose Concentrated Liquid, 2 x 800 ml at £7.98 (about £4.99 per litre), has 3,025 ratings at 4.6, but its listing does not name vegetables and most reviewers feed houseplants and flowers. The 2.5 L bottle sold under a Topline listing at £19.89 does name vegetables, but it has 71 ratings, costs about £7.96 per litre, and quotes a dose that differs from the manufacturer's page.
Westland Boost, a 2 kg slow-release tub at £11.64, claims a six-month supply and high potassium for fruit production. Cracked tubs appear in many reviews. The Topline soluble powder, 2 x 1.2 kg at £14.99, names vegetables, but it has five ratings and no dose on the listing, so treat its 4.7 stars with caution. If you cannot decide between formats, the granular versus liquid page gives one recommendation by growing method.
Who should skip which
Skip the Performance Organics bag if you grow beside a patio or balcony and a strong smell would bother you, or if you are feeding more than a few beds on a budget. Skip Westland Growmore if you want a listing that names vegetables, or if a split tub would be a problem because delivery is to a flat. Skip Westland Boost for open beds of leafy crops, because the reviews are about containers. Skip the 800 ml liquid if you want reviews from vegetable growers.
The Performance Organics title says bee, pet and child friendly, and the 2.5 L liquid says child and pet friendly. Both are listing claims that we have not tested, and one Growmore reviewer says their dogs like it. Store every fertiliser out of reach, and call a vet if a pet eats some.
Common questions
Which is the best fertiliser for vegetables in the UK?
Among these seven amazon.co.uk listings, Miracle-Gro Performance Organics Fruit & Veg, 1 kg, is our top pick because its listing names fruit and vegetables as the item type. It costs £7.99 and has 4.6 out of 5 from 1,284 ratings.
Is Growmore good enough for vegetables?
Growmore is a general feed that many UK growers use on vegetable beds, and the Westland and Topline tubs both sell at a low price per kilogram. The Westland listing does not name vegetables, so check the vegetable rate on the pack. Growmore leans towards nitrogen, so fruiting crops may need a different feed once flowers form.
Which listing is best value for a large plot?
Westland Growmore 8 kg at £16.95 is the cheapest per kilogram, at about £2.12 per kg. At 70 g per square metre it covers about 114 square metres, which is around 15p per square metre by our arithmetic. Reviewers report split tubs, so check the tub on delivery.
Is Miracle-Gro Performance Organics worth the higher price per kilogram?
It costs about £7.99 per kg against about £2.12 for Westland Growmore. You pay more for a listing that names fruit and vegetables and for an organic claim. It makes most sense for a few raised beds, and less sense for a full allotment.
Do the star ratings tell me which is best for vegetables?
No. Six of the seven listings sit between 4.5 and 4.6 out of 5, and the seventh has only five ratings. Read whether the listing names vegetables, how many ratings back the score and what the reviews say about packaging.
