Best guano fertiliser

Updated: October 2026

You opened amazon.co.uk looking for the best guano fertiliser and found a 700 g VitaLink tub, a German stick count in the thousands, and shop pages that print an NPK the listing does not. This page judges only the nine saved listings in our [guano fertiliser comparison](/hub/fertiliser-soil-and-bark-mulch/guano-fertiliser). A top pick here is a job with a skip, not a UK award and not a lab result. Products Compared has not tested these packs. Prices are the saved snapshot in GBP. If you still need the order of checks rather than a name, use the [guano fertiliser buying guide](/hub/fertiliser-soil-and-bark-mulch/guano-fertiliser/sub/guano-fertiliser-buying-guide).

A top pick is a job, not a UK award

Best, on a search page, usually means a smaller tub or a star count whose texts were not written in the United Kingdom. The live 700 g VitaLink listing, ASIN B01ARR7CKG, is not in this set and does not replace about £26.25 on the 3.5 kg tub. A pick here uses the saved listings, the review country, and the claims they print. It is not a UK award. A shop NPK does not move onto another tub, and 100% organic is not a certificate.

COMPO sticks when you want a three-month seabird insert

COMPO B0007VK1LK is the three-month seabird insert for palms, ferns, pond plants, and other green plants, about £15.78 for thirty sticks. According to the product data, use the number on the pack, push a stick 5–6 cm from the stem, and replace it from March to October. The UK listing says no fertilisation in winter. English on the pack is not guaranteed. The mixing field 11:4:8 is not an NPK. Skip the sticks for bat powder or UK review texts. None of the fifty saved texts is from the United Kingdom. A German winter half-dose disagrees with this ASIN.

Skip the tub for a cheap flower stick or a 25 kg sack

Flower’s twenty sticks are about £5.97. They name flowers, name no animal, and print no dose. The texts are from Spain and mention broken or short packs. They are the cheap blister, not a powder substitute. CULTIVERS 25 kg is about £50.31 and names a vegetable garden, with a high NPK and no numbers, and texts from Spain and France. Cheaper per kilogramme is not the pick if you garden in pots. Fertiberia’s litre has no star line. Neither that bottle nor the 1 kg CULTIVERS bag is a top pick here.

Match the job, then stop

Buy VitaLink B01ARR7GVG for bat powder and UK review texts if you can store 3.5 kg without a printed NPK. Buy the COMPO sticks for a palm, fern, or pond plant. Buy Flower’s twenty sticks only under £10 for flowers. Buy the 25 kg sack only with a plot and dry storage.

Common questions

Which guano fertiliser in this set has UK review texts?
VitaLink B01ARR7GVG, 4.6 from 517, with fifty saved texts marked as written in the United Kingdom. Guanokalong has one UK sentence on three reviews. The dearer VitaLink listing has two stars and no text. COMPO’s and Flower’s large counts are not UK samples in the saved listings.
Who should buy the COMPO sticks instead of the VitaLink tub?
You should, if the plant is a palm, fern, pond plant, or other green plant and you want a three-month seabird insert. You should not, if you wanted bat powder, a vegetable bed, or reviews written in the UK. The sticks and the tub are different jobs.
Is the 700 g VitaLink tub the one being compared?
No. That live ASIN is not in this comparison. The powder pick is the saved 3.5 kg listing at about £26.25. Do not swap the snapshot for the smaller tub’s live price.
Why not the listing with 2,853 reviews?
Because the fifty saved texts are not from the United Kingdom. A large star count without a UK sample is not the powder job, and COMPO is a stick for palms rather than a tub of bat guano.
Is Guanokalong the better tub because a shop prints NPK 1-10-1?
No. That figure is a retailer page, not the amazon.co.uk product data for B01LOWLQJQ. The listing has no bullets and no NPK. Three reviews do not beat 517 UK texts on the VitaLink tub for the powder job.
What should I buy if I only want to spend under £10?
Flower’s twenty sticks at about £5.97, knowing they name flowers, print no dose, and carry Spanish review texts about broken packs. Fertiberia’s litre is about £8.49 with no star line. Neither is the powder pick.
Does top pick mean a lab test or a UK award?
It means a conditional choice inside this saved set for a stated job. Products Compared has not tested the packs in a laboratory, and the page does not claim a UK award.
