How to use guano fertiliser

Updated: October 2026

You already have a tub, a blister, or a litre on the potting bench, and a search result is offering grams that belong to another brand. How to use guano fertiliser, for this set, starts with the rate printed on the pack in your hand. A UK shop page for VitaLink, Guanokalong, or Plagron is not that rate. Products Compared has not trialled these methods. This page only uses what the saved amazon.co.uk listings and their reviews actually describe. The [guano fertiliser comparison](/hub/fertiliser-soil-and-bark-mulch/guano-fertiliser) is the product table. If you still need to choose a form, go back to the [guano fertiliser buying guide](/hub/fertiliser-soil-and-bark-mulch/guano-fertiliser/sub/guano-fertiliser-buying-guide).

Use the rate on your pack, not a shop recipe

Shop spoons are not on these listings. Two 10 ml spoons per 3 litres are not in the amazon bullets for either VitaLink ASIN, and shop pages disagree on Guanokalong. Copying 100 g per 15 L or 200 g per m² onto Flower, CULTIVERS, or COMPO invents a dose the product data does not give. The rule is one pack, one label. If the tub is silent, do not fill the silence from a shop. A sealed retail tub is not an animal-by-product premises. Call APHA if you import or repack as a business.

Powder and tea only where the listing describes them

VitaLink B01E5NU3R2 names powder on soil or a guano tea, and the bullets still print no spoon. VitaLink B01ARR7GVG leaves method to the reviews. In the Amazon reviews, UK reviewers top-dress or mix a paste, then water in. That is not a recipe for every tub. Flower’s 2 kg claim of 2 kg = 40 m² is not a rate for VitaLink. Flower’s sticks, Guanokalong, and both CULTIVERS packs have no application bullet. If the pack is silent, stop.

Sticks go in a hole 5–6 cm from the stem

COMPO’s UK bullets say to use the number on the back of the pack, push a stick 5–6 cm from the stem, and cover it. Replace it about every three months from March to October. The same listing says no fertilisation is needed in winter. A German half-dose from November to February disagrees with this ASIN. Flower’s twenty sticks name flowers and print no distance. Do not copy COMPO’s 5–6 cm onto that blister. In the Amazon reviews, texts that are not from the UK mention a damaged blister and missing sticks. That is a packing complaint, not a method.

Smell, lumps, and dry storage

UK VitaLink reviews do not agree on smell: almost nothing when the powder is dry, ammonia in a paste. Do not merge that with the 25 kg sack, whose Spain and France texts also disagree. One UK review reports hard lumps, and the product data gives no fix. COMPO says store the sticks dry, above 6 °C and below 35 °C, out of sunlight. A sack needs a dry place of its own. Loft droppings are not a method. That limit is on the bat or seabird guano page, and which pack to buy is on best guano fertiliser.

If the pack is silent, stop

Follow the bullet on the pack you hold. A tea is named only on VitaLink B01E5NU3R2, and even there no spoon is printed. A 5–6 cm hole and a March-to-October interval belong to the COMPO sticks. A 40 m² figure belongs to Flower’s 2 kg granules. If the pack you hold is silent, stop rather than borrow a rate from another brand.

Common questions

How do I apply guano powder if the amazon bullets give no spoon rate?
Read the pack in your hand. VitaLink B01E5NU3R2 names powder or a tea and still prints no spoon. B01ARR7GVG leaves method to UK reviewers, who top-dress or mix a paste and water in. If the pack is silent, do not copy a shop recipe from another brand.
How do I make a guano tea without using another brand’s recipe?
Only where the listing describes a tea. In this set that is VitaLink B01E5NU3R2, which says mix with water and gives no spoon. Two 10 ml spoons per 3 litres is a retailer page, not the amazon bullet. If your tub does not mention a tea, do not make one from a blog.
How do I insert COMPO sticks, and do I feed in winter?
Use the number on the back of the pack, make a hole 5–6 cm from the stem, insert, and cover. Replace about every three months from March to October. The UK listing says no fertilisation is needed in winter. Do not use a German half-dose on this ASIN.
What do I do if the powder smells or has gone lumpy?
Treat smell as unresolved. UK VitaLink texts disagree, and the 25 kg sack’s non-UK texts disagree in a different way. One UK review reports hard lumps. There is no official fix in the product data. If dust has caused a reaction, that is a professional case, not a forum tip.
Where do I store a tub or a 25 kg sack?
COMPO prints dry storage above 6 °C and below 35 °C, away from sunlight. A 25 kg sack needs a dry place of its own. A sealed retail tub in a house is not an animal-by-product premises. Keep the lid on so damp air does not cake the powder.
Can I use the Guanokalong grams from a hydro shop on VitaLink?
No. Those shop pages do not match each other, and neither page is the amazon bullet for VitaLink or for Guanokalong B01LOWLQJQ. Do not copy those rates onto another brand.
When do I stop and call a professional?
If building work may affect a bat roost, if you manage agricultural land and are unsure about a permit or a nutrient plan, if you import or repack as a business (APHA), or if a person or pet has swallowed product or reacted to dust.
