The best conifer fertilisers, compared.
Top pick: Empathy After Plant Evergreen, 1 L Best value: Empathy After Plant Evergreen, 1 L – About £9.46 with 4.4 from 753 United Kingdom reviews, the largest file in this set, for a liquid you mix for pots and new plantings. Updated October 2026.
Conifer fertiliser on amazon.co.uk is a pack titled for conifers, evergreens, or conifers and shrubs. You buy pellets, organic granules, or a liquid drench for a hedge, a specimen, or a dwarf conifer in a pot. Most established trees in UK soil do not need a routine feed. The Royal Horticultural Society treats a general-purpose granular fertiliser in late winter as optional, then a mulch, and says pots need liquid from early spring to late summer. A usable pack has English instructions, a declared analysis or an honest dilution, and a size that matches a few pots or a long hedge. Do not feed after September. Brown or yellow foliage is usually drought, waterlogging, wind, frost, cypress aphid, disease, or a cut into old wood. The [conifer fertiliser buying guide](/hub/fertiliser-soil-and-bark-mulch/conifer-fertiliser/sub/conifer-fertiliser-buying-guide) starts with that job. Keep granules off the leaves and off the stem. Mulch damp ground to about 5–8 cm, with a gap at the bark.

Question 1 of 2
Where is the conifer?
Empathy After Plant Evergreen, 1 L, is a United Kingdom liquid you mix with water for evergreens, at about £9.46. Across 753 amazon.co.uk reviews the star line is 4.4, scaled to 88, the deepest sample in this set, with United Kingdom texts in the file. Those texts often name greener conifers, leylandii, yew, fir, laurel and bay. Other reviews report no change, plants that died after planting, and bottles that arrived unsealed. The listing does not print an NPK. The mixing-ratio field reads 1:4.5. That is a field on the card, not a confirmed watering-can recipe. The maker's page states 20 ml or 40 ml per 4.5 litres. Those figures are not the same. Most saved uses are a root drench. One text describes a foliar spray on leylandii. The maker's catalogue describes the bottle as a seaweed and amino-acid biostimulant and as RHS-endorsed. That is the maker's statement. It is the best value here for a measured evergreen drench with a UK review file, not a printed analysis and not a long-hedge granule.
Pros
Cons
Best for: A few pots or a new planting, if you will follow the maker's 20 ml or 40 ml per 4.5 litres and you wanted the UK-reviewed liquid in this set.
Less suitable: A long hedge, or anyone who needed a printed NPK on the amazon listing.
Specifications
Common questions
What size is the Empathy bottle?
The title, unit count and liquid volume all say 1 L. Item weight is 1.14 kg. The model is APEG1L.
Does the listing print an NPK?
No. The mixing-ratio field reads 1:4.5. The maker's page states 20 ml or 40 ml per 4.5 litres. Those figures are not the same.
What do the saved UK reviews mention?
Greener conifers, laurel, bay and yew appear often. Other texts report no change, plants that died after planting, and bottles that arrived unsealed.
Cultivers organic liquid for conifers and hedges, 5 L, is an organic-labelled liquid at about £35.29, with a listing NPK of 4-1-4. Across 45 amazon.co.uk reviews the star line is 4.4, scaled to 88. That score is tied with Empathy and the Cultivers 5 kg bag, from a smaller sample. The saved texts are marked France, Belgium and Spain, not a United Kingdom survey. Application is irrigation, and there is no millilitre-per-litre dose in the file. The listing names pines, spruces, cypresses and thuyas. The top pick is that tied score plus a printed 4-1-4 claim, not a laboratory ranking, and not proof the 5 L outperforms the 753-review Empathy bottle. It suits a large irrigation jug when you can accept an EU review file. Skip it if you need a UK review file or a measured capful.
Pros
Cons
Best for: Several pots or a short hedge on an irrigation routine, if you wanted a 5 L organic-titled liquid and can accept an EU review file.
Less suitable: Anyone who needed a printed dilution, a United Kingdom review sample, or a 1 L measured drench.
Specifications
Common questions
What NPK does the 5 L liquid print?
The bullets and the mixing-ratio field say 4-1-4. That is a listing claim, not a tested analysis.
How do you apply it?
The listing says irrigation. There is no millilitre-per-litre dose in the file.
Are the saved reviews from the United Kingdom?
No. The saved texts are marked France, Belgium and Spain.
Cultivers conifer and hedge granules, 5 kg, are organic-labelled microgranules for pines, firs, thujas, cypresses and cedars, at about £27.28. Across 25 amazon.co.uk reviews the star line is 4.4, scaled to 88, with Spain texts only. The listing prints NPK 8-1-5, which differs from the 6-7-10 claim on the 1 kg bag in this set. The liquid-volume field also prints 1 litre on a 5 kg granule title. The file records the clash and does not resolve it. There is no grams-per-square-metre rate. It is a mid-size imported sack if you wanted more than 1 kg and can accept an EU review file, not a UK-labelled pellet.
Pros
Cons
Best for: Several trees or a longer hedge, if you wanted a 5 kg organic-titled sack and can accept a Spain review file.
Less suitable: Anyone who needed United Kingdom review texts, or a pack whose volume and weight fields agree.
Specifications
Common questions
What NPK does this 5 kg listing print?
The bullets and the mixing-ratio field say 8-1-5. That is a listing claim. The 1 kg Cultivers bag in this set prints 6-7-10.
Why does the listing also say 1 litre?
The liquid-volume field prints 1 litre on this 5 kg granule title. The file records the clash and does not resolve it.
Cultivers organic conifer and hedge fertiliser, 20 kg, is an organic-labelled microgranule sack at about £69.99. Across 16 amazon.co.uk reviews the star line is 4.1, scaled to 82. The five saved texts are marked Spain. The bullets print NPK 6-7-10. One Spain review says every Cultivers crop bag the buyer opened was 8-7-5. There is no grams-per-square-metre rate, and the listing itself asks how often to apply. One review names leylandii. It is the bulk row if you have many trees and will live with an imported label, not a UK-certified analysis and not a pot-sized pack.
Pros
Cons
Best for: A long hedge or several large specimens, if you wanted one 20 kg sack and can accept an imported label.
Less suitable: A few pots, anyone who needed a UK review file, or a shopper who wanted the printed NPK to match every bag.
Specifications
Common questions
What NPK does the 20 kg bag print?
The bullets say 6-7-10 and the mixing-ratio field is 6:7:10. One Spain review says every Cultivers crop bag the buyer opened was 8-7-5.
Are the saved reviews from the United Kingdom?
No. The five saved texts are marked Spain.
Cultivers conifer and hedge granules, 1 kg, are organic-labelled microgranules at about £15.58, with a listing NPK of 6-7-10. Across 11 amazon.co.uk reviews the star line is 3.9, scaled to 78. The two saved texts are marked Italy and Spain, not a United Kingdom survey. The listing names pines, spruces, cypresses, thuyas, firs and cedars and calls the product slow-release. There is no grams-per-square-metre rate. No certifier is named behind the 100% organic line. It is a mid-size imported granule if you will follow the pack chart, not a UK review sample and not a printed statutory statement.
Pros
Cons
Best for: A short hedge or a few specimen conifers, if you wanted a 1 kg organic-titled granule and can accept an EU review file.
Less suitable: Anyone who needed United Kingdom review texts, a printed application rate, or a UK brand on the box.
Specifications
Common questions
What NPK does this 1 kg listing print?

Altea organic conifer fertiliser, 1.5 kg, is an organic-labelled granule for conifers and evergreens in pots and gardens, at about £9.50. Across 2 amazon.co.uk reviews the star line is 3.2, scaled to 64, the weakest scored row in this set. The only United Kingdom text says the instructions for use are not in English. The title and unit count print 1.5 kg. The item-weight field says 2 kg. NPK and a grams-per-square-metre rate are both missing from the bullets. It is a small imported bag if you can read the sheet that arrives, not a UK-labelled specialist and not a review-backed pick.
Pros
Cons
Best for: A buyer who can read the enclosed sheet and wanted a small organic-titled bag at the entry price.
Less suitable: Anyone who needed English on the packet, a printed rate, or a United Kingdom review file.
Specifications
Common questions
How much is in the Altea pack?
The title and unit count say 1.5 kg. The item-weight field says 2 kg.
Does the listing print an NPK?
No. NPK and the mixing-ratio field are not stated.
What does the saved UK review say?
The instructions for use are not in English. That is the only United Kingdom text in the file.
Substral Naturen conifers, hedges and shrubs, 1.2 kg, is sold for spruce, thuja, box, privet, juniper, and also deciduous trees, at about £19.32. The bullets say one application lasts up to 3 months. There is no amazon.co.uk star line in the file, so this row is not a measured rank. Form, NPK and a grams-per-square-metre rate are missing. Evergreen Garden Care is the manufacturer. Country of origin on the listing is Germany. The bullets call it organic-mineral, suitable for organic farming, and free of animal ingredients. Those are listing claims. It is the one-dose hedge row if you will follow the pack and accept a silent review line.
Pros
Cons
Best for: A hedge you want to feed once in the growing window, if you will follow the pack and can accept a missing star line.
Less suitable: Anyone who needed a scored amazon.co.uk review sample or a printed analysis.
Specifications
Common questions
How long does Substral say this pack lasts?
The bullets say up to 3 months from one application. There is no grams-per-square-metre rate in the file.
Is there an amazon.co.uk star line?
No. The card has no star rating and no review count.
Vitax Conifer & Shrub 2.5 kg, twin pack, is pelleted feed titled as two boxes of 2.5 kg, at about £35.03. The unit-count and item-weight fields still print 2.5 kg, so you should check that two boxes arrived. There is no amazon.co.uk star line in the file, so this row is not a measured rank. The first bullet also calls it an azalea and rhododendron fertiliser. NPK is missing from this listing. The coverage field reads Low. A maker label PDF, which is not this raw card, prints 10.0 : 7.5 : 10.2, shown in the UK as 10 : 3.3 : 8.5. It is the UK pelleted specialist in this set if you will confirm the twin pack and follow the English packet, not a review-backed pick.
Pros
Cons
Best for: A UK shopper who wanted a named Vitax pellet for conifers and shrubs and will check that two boxes arrived.
Less suitable: Anyone who needed a scored review sample, or a listing whose pack fields already agree.
Specifications
Common questions
Is this one box or two?
The title says two of 2.5 kg and the number of packs is 2. The unit-count and item-weight fields still print 2.5 kg.
Does the listing print an NPK?
No. NPK is not on this listing. The first bullet also calls it an azalea and rhododendron fertiliser. A maker PDF, which is not this card, prints 10.0 : 7.5 : 10.2.
Eight amazon.co.uk listings were read from the stored pages. The number on each card is the star line scaled to 100, so 4.4 becomes 88. A missing star line is not given a measured rank. There is no laboratory test. The top pick is Cultivers organic liquid for conifers and hedges, 5 L, on a tied score of 88 with a printed NPK of 4-1-4. The best value is Empathy After Plant Evergreen, 1 L, at about £9.46 with 4.4 from 753 United Kingdom reviews. The weights below sum to 100. They describe how this page reads a listing. They are not a second score on top of the star line.
Review sample
30%Star rating on amazon.co.uk, then whether the saved texts are from the United Kingdom and how large the file is. Empathy at 4.4 from 753 UK texts is the deep file. A missing star line adds nothing here. A two-review file cannot carry the same weight as 753.
Label you can follow
30%English instructions, a printed NPK or a published dilution, and no unresolved clash between two figures on the same card. A 1:4.5 scrape field is not treated as the maker's 20 ml or 40 ml per 4.5 litres. Cultivers NPK claims that differ by bag size stay as a clash.
Form and calendar
25%Late-winter granules for open ground, liquid for pots in the growing season, and no feed after September. A liquid titled for a long hedge is a weaker match than a granule sized to that hedge. Brown foliage is not scored as a feeding job.
Pack size for the job
15%A 1 litre drench against a long hedge, a 1 kg bag against a few trees, and a 20 kg sack against a long run. Shelf price is the stored amazon.co.uk figure. It is not a national average.
Match the job, the calendar and a label you can follow before you match the star line. Prices below are the stored amazon.co.uk shelf prices. This is not a laboratory test.
Conifer fertiliser on amazon.co.uk is a pack titled for conifers, evergreens, or conifers and shrubs. You meet it as pellets, organic granules, or a liquid you water in. Most established trees in UK soil do not need a routine feed. The Royal Horticultural Society growing guide treats a general-purpose granular fertiliser in late winter as optional, then a mulch. The same guidance says pots need liquid from early spring to late summer, and that you should not fertilise after September.
Drought, waterlogging, wind, frost, cypress aphid, disease, or a cut into old wood are the usual causes. Most conifers will not reshoot from old wood. Yew is the exception, and thuja is less reliable.
Stop after September. Feed when the soil is moist, not in frost or a hot drought. A 1 litre weekly drench is a poor way to feed about 20 m of leylandii.
The Empathy card field reads 1:4.5. The maker's page states 20 ml or 40 ml per 4.5 litres. Cultivers NPK claims are not the same on the 1 kg, 5 kg and 20 kg listings.
Name the job before the brand. A pot, a new planting, a specimen and a long hedge are not one rate. Most established conifers in UK soil do not need a routine feed. The Royal Horticultural Society treats a general-purpose granular fertiliser in late winter as optional, then a mulch, and says containers need liquid from early spring to late summer. Nothing goes on after September. Gardeners' World says feed when the soil is moist, and not in frost or a hot drought.
A label you can follow is in English and states an NPK or a dilution you can measure. In Great Britain, a prescribed fertiliser needs a statutory statement under the Fertilisers Regulations 1991, and section 68 of the Agriculture Act 1970 requires a written statement to the buyer. The NPK lines in this set are listing claims. Cultivers prints 6-7-10 on the 1 kg and 20 kg granules, 8-1-5 on the 5 kg granules, and 4-1-4 on the 5 L liquid.
Three typical situations, each with a recommendation from this comparison.
Leylandii, thuja and yew often need water and a pest check before a bag. If you still feed, use a late-winter granule sized to the hedge, not a weekly 1 L drench. Cultivers conifer and hedge granules, 5 kg, are about £27.28, with a listing NPK of 8-1-5 and 4.4 from 25 Spain reviews. There is no grams-per-square-metre rate.
Containers are the case for liquid, from early spring to late summer. Empathy After Plant Evergreen, 1 L, is about £9.46, with 4.4 from 753 United Kingdom reviews. The maker's page states 20 ml or 40 ml per 4.5 litres. The listing does not print an NPK.
Water first. An after-planting liquid is a measured extra, not a substitute for planting practice. Empathy After Plant Evergreen, 1 L, is the UK-reviewed liquid in this set, at about £9.46. Do not treat brown needles in year one as a feed emergency.
The top pick is Cultivers organic liquid for conifers and hedges, 5 L, at about £35.29. The listing prints NPK 4-1-4, amazon.co.uk shows 4.4 from 45 reviews, and the card score of 88 is tied with Empathy and the Cultivers 5 kg bag. The saved reviews are marked France, Belgium and Spain, and the listing does not give a millilitre-per-litre dose. The best value is Empathy After Plant Evergreen, 1 L, at about £9.46, with 4.4 from 753 United Kingdom reviews. The maker's page states 20 ml or 40 ml per 4.5 litres, and the card's 1:4.5 field is not that recipe. A 1 litre drench is a poor match for a long hedge. None of these scores is a laboratory test.
Empathy After Plant Evergreen, 1 L
About £9.46 with 4.4 from 753 United Kingdom reviews, the largest file in this set, for a liquid you mix for pots and new plantings.
