Citrus fertiliser buying guide

Updated: October 2026

You have a pot lemon on a UK windowsill or in a cool conservatory, and the search results mix a 200 ml high-street bottle, a ready foliar spray, 12-week sticks, and a 4 lb bag priced like a grove product. A citrus fertiliser buying guide has to start with the form you will actually use, then the season printed on the label, then whether the review file is from the United Kingdom. Brand names come after those checks. The [citrus fertiliser comparison](/hub/fertiliser-soil-and-bark-mulch/citrus-fertiliser) holds the eleven amazon.co.uk listings we kept, with prices in GBP. We read those listings on 21 October 2026. We did not run a lab test.

What citrus fertiliser means on amazon.co.uk

Citrus fertiliser in this category is a pot-plant feed named for lemon, orange, lime, kumquat or calamondin. It is not a farm grove product and it is not box foliar. A Mediterranean olive food belongs only if the listing names citrus as the job. The kept packs split into liquids, one foliar spray, one stick pack, and granule bags. Citrus Focus and Vitax winter powder appear on the live search and are not ranked rows. If you wanted a weekly drench, start with the liquids. The best citrus feed UK page then assigns one job per kept product.

Match the form to the job

A dilute liquid suits a watering can you already use. According to the product data, Westland prints a measuring doser and a mixing field of 1:900. COMPO prints 1:10. The 100 ml generic prints no ratio at all. A missing dose is a buying problem, not a footnote. Sticks suit someone who will push them below the soil line and still water as usual. Foliar spray is a top-up, not a root drench. Granules suit outdoor soil you can scratch. For one terracotta pot, a 200–500 ml liquid is the matching size. If the shed already holds tomato feed, that comparison sits on citrus feed vs tomato feed.

Read the card before the stars

Printed analysis comes next, and only if the listing shows it. COMPO’s item type prints 3.1 + 0.5 + 4.1. Jobe’s prints 3-5-5. Miracle-Gro’s mixing field is 13:7:13. Westland, both Baby Bio twin packs, the bundle, UK GROW, Devonia and yanzisura have no usable NPK on the listing. Cultivers prints NPK +74% M and a mixing field of 1:0:0, which the product data does not show as a usable analysis. Season is a separate line. Baby Bio’s cheaper twin pack and the bundle say year-round. The other kept products do not print a winter formula. That calendar is on winter citrus feed. Westland has 50 United Kingdom texts. Baby Bio B00L5P0I3I has 47. Do not read an EU or US sample as a UK conservatory survey.

What to decide before you open the table

This guide does not rank the eleven packs, and it does not add Citrus Focus or Vitax. Organic wording is listing copy until a UK certifier is named. Great Britain does not require a product mark on fertilisers. Northern Ireland still uses CE. If you will dilute weekly, a 200–500 ml liquid matches one pot. If you will not measure, sticks are the other household shape and you still water as usual. Once the form, the season line and the review locale match what you will do, open the main table.

Common questions

Do I need liquid, sticks or granules for one pot lemon?
A weekly liquid matches one conservatory pot if you will dilute it. Sticks match a pot you will not measure every week, provided you still water as usual. Granules in pounds match outdoor soil and storage space. Foliar spray is a top-up, not the only feed. For a single terracotta lemon, the 200–500 ml liquids in this set are the usual size. A 4 lb import is a different job.
Do I need a separate winter citrus feed?
The Royal Horticultural Society describes a higher-nitrogen summer feed and a more balanced winter feed. In this capture, Baby Bio claims one year-round bottle. The other kept listings do not print a winter formula. Vitax-type winter powder appears on the live search and is not a ranked row. A year-round label does not rebut the RHS calendar. It only tells you what that bottle claims.
Is foliar spray enough on its own?
No. UK GROW’s listing tells you to spray leaves and branches. That is a foliar top-up. Citrus in pots still need a root drench unless the pack in your hand says otherwise. Treating yellow leaves with more leaf spray, while the compost sits wet, is a common mistake. Water and drain first, then feed at the roots if the bottle is a concentrate.
Why are some bags £36 to £71?
Those stickers are Jobe’s 4 lb at £36.79 and Miracle-Gro 4.5 lb at £71.54. Both are import-sized granules with United States review texts. The household liquids in this set sit between about £7 and £12. A higher price is more product and a different form, not proof of a stronger UK pot feed. Skip the bags if you have one lemon and nowhere dry to store 2 kg.
Which listings have United Kingdom review texts?
Westland has 50 United Kingdom texts. Baby Bio B00L5P0I3I has 47. UK GROW has two. Cultivers has one. COMPO’s saved texts are EU. Jobe’s and Miracle-Gro texts are North American. The cheaper Baby Bio twin pack, the bundle, Devonia and yanzisura have no saved texts on the listings. A large star count without a UK file is still a listing figure, not a UK verdict.
Does organic on COMPO or Jobe’s mean a UK certificate?
No. COMPO uses Bio / organic on the title and item type, with no UK certifier named. Jobe’s bullets use OMRI listed and USDA wording, which is a US scheme. Cultivers says 100% organic and names no certifier. Treat those lines as manufacturer copy. They are not a Soil Association mark and they are not a reason to double the dose.
