Best hedge fertiliser

Updated: October 2026

A search for the best hedge fertiliser on amazon.co.uk usually wants one winner. These eight listings will not give you that. They are different jobs: a named-species liquid, a general 8 kg tub, a photinia granule with no English dose, and a box foliar tablet. Stars do not compare those packs. This page names a pick for a stated job and a skip, using the amazon.co.uk snapshot in the [hedge fertiliser comparison](/hub/fertiliser-soil-and-bark-mulch/hedge-fertiliser). If you buy through a link on this page, we may earn a commission at no extra cost to you.

Best depends on the job

An established leafy hedge in reasonable soil often needs mulch, not a bottle. If it already looks short of nutrients, or the soil is light and sandy, you are shopping. If it does not, walk away. The jobs split three ways: a soil feed for privet, laurel, yew, or hawthorn; a general tub for borders as well; and a foliar tablet for Buxus. Bone meal, a Vitax planting pouch, and a caterpillar treatment are not in this comparison. A liquid that names the species fits a hedge-only job. An 8 kg tub fits one general feed you can weigh. The criterion is the job. How to choose the form sits on the hedge fertiliser buying guide.

Picks from these listings

Hedge Boost, 5 litres, at about £22.99, is the named-species soil drench: privet, boxwood, laurel, yew, and hawthorn. The mixing field is 1:5, against a review-quoted 10 ml per litre. The star line is 3.9 from 16 reviews. Westland Growmore, 8 kg, at about £16.95, is the general tub, 4.5 from 465 reviews. Hedges are not named. According to the manufacturer, the brand page prints 7-7-7 and 135 g per square metre. TOPBUXUS, 10 tablets, at about £24.95, is the box foliar pick: one tablet in 1 litre for 10 square metres. It does not kill caterpillars. Topline at about £23.99 costs more, and its 20:20:20 field clashes with a review of 7-7-7.

Skips that look like winners

LERAVA is 4.6 kg at about £49.99, titled for hedges and photinia, with 4.6 from 310 reviews. The product data has two United Kingdom-marked reviews, then texts from Spain and Belgium. Both United Kingdom texts say the instructions were not in English. There are no grams. Do not treat 310 as a UK written sample. Do not add the three UK GROW star counts. Skip TOPBUXUS if you wanted a caterpillar killer. One United Kingdom review returned it for that reason. Buxus after blight stays on the box hedge fertiliser page. None of the eight listings is a planting pouch.

When no listing is the buy

Walk away if the hedge is already green in decent soil, if you needed a laboratory ranking, or if you wanted one bottle to feed the hedge and kill caterpillars. Skip Topline as a settled analysis. The listing ratio and the United Kingdom review disagree.

Common questions

What is the best fertiliser for an established laurel or privet in this set?
If you want the species named and a soil drench, Hedge Boost is the pick: privet, boxwood, laurel, yew, and hawthorn, 5 litres, about £22.99. The rate field is 1:5 against a review-quoted 10 ml per litre, and the star line is only 3.9 from 16 reviews. If you wanted a general 8 kg tub and a brand gram rate instead, Westland Growmore is the better match, even though hedges are not named. Established laurel in reasonable soil may need neither.
Is a dedicated liquid better than Growmore?
Only for a hedge-only job that needs the species on the label. Growmore is the wider tub: 8 kg, about £16.95, 4.5 from 465 reviews, with 135 g per square metre on the brand page. Hedge Boost is the narrower bottle: named hedges, a conflicting dilution, a thinner review file. A liquid is not stronger as a class. It is a different form for a different place on the plant.
Should I buy the 5 litre UK GROW or Hedge Boost?
Hedge Boost, if you wanted named species and a soil dilution in print. The 5 litre UK GROW title is the same few-drops concentrate as the 250 ml and 500 ml bottles, with the same 4.2 from 42 line. Its liquid-volume field says 1 litre against a 5 litre title. One review names cherry laurel; the bullets still do not give millilitres. Buy the large UK GROW only if you already use that line and wanted volume.
Is LERAVA worth £49.99 if the UK reviews cannot read the dose?
Not as a first UK buy. You pay the highest price in this set for a photinia-and-hedge granule with no grams in the product data. Two United Kingdom texts flag the language. The 310 ratings are not 310 UK written reviews. Open it only if you already know a rate from another source and wanted that title.
Which listing is the skip for box owners who wanted a caterpillar killer?
TOPBUXUS Health-Mix. It is foliar nutrition for Buxus, 10 tablets, about £24.95. The listing does not say it kills caterpillars. One United Kingdom review sent it back for that reason. Keep pest control as a separate product. The tablet remains the box-foliage pick when nutrition is the job.
Can I add the three UK GROW star counts together?
No. The 250 ml, 500 ml, and 5 litre titles share one 4.2 from 42 line and the same nine United Kingdom texts. Adding them triple-counts one sample. Choose a size, not three tested winners.
Is Westland the best value 8 kg tub here?
Yes, in this snapshot. It is about £16.95 against Topline at about £23.99, with the deeper review file and a brand page that prints 7-7-7 and 135 g per square metre. Hedges are still not named, and the listing bullets have no grams. Topline wins only if you already wanted its February to October calendar and accepted the unresolved 20:20:20 versus 7-7-7 clash.

Public UK and maker sources from the research digest, used for this page in October 2026. Prices, stars and review counts are from the eight amazon.co.uk listings in the stored product files. A mixing-ratio field is not an NPK. The 7-7-7 line is the Westland brand page. TOPBUXUS is foliar nutrition, not a caterpillar killer. LERAVA's 310 figure is the listing star line, not 310 UK written reviews.
