The best palm fertilisers, compared.
Top pick: Cycas and palm dry feed Best value: Jobe's fern and palm spikes – About £6.99, score 79, from 4.3 and 4,359 United Kingdom reviews. Reviewers in that sample call the price good value. Updated October 2026.
Palm fertiliser is a liquid, a set of spikes, or granules sold for palms, and often for cycads or ferns on the same pack. In the UK you buy it for a house palm in a pot, or for a hardy outdoor palm such as a windmill palm or a dwarf fan palm. A suitable pack shows a dose you can measure, an analysis or a named trace such as magnesium or manganese, and whether it is for pots, open ground, or both. A general green-plant food that only mentions palms is a different job from a concentrate named for palms. Outdoor palms in Britain should not be fed through winter. Stop by late summer so new growth can harden. Indoor palms follow a summer calendar too: a general liquid from April to mid-September, and none for six to eight weeks after potting. Do not copy an all-year indoor habit onto a palm in the ground. Form, dose and season are set out in the [palm fertiliser buying guide](/hub/fertiliser-soil-and-bark-mulch/palm-fertiliser/sub/palm-fertiliser-buying-guide).

Personal buying guide
Question 1 of 2
Where is the palm?
This 40 g dry pack is titled for Cycas revoluta, palm, and toddy palm, and the title says the powder is enough for 20 litres after dissolving. The target-species field says cycad and the uses field says palm trees. No NPK percentages are printed, and a field that reads 20:1000 is not a mixing sentence you can follow on its own. The only amazon.co.uk review scores 5.0, with the title 'Very good buy' and the body 'Yes', and it does not describe a plant. A unit-count field of 1 gram conflicts with the 40 g item weight. Country of origin in the capture is Bulgaria, the brand line is Generic, and the price is £6.98 on 19 October 2026. The score of 80 maps that single star line. It is not a result on a sago or a palm.
Pros
Cons
Best for: A buyer who already uses this cycad powder and only needs a small dissolve-and-water pack
Less suitable: A first palm feed, because one word of praise is not a result on a plant
Specifications
Common questions
Is this a palm fertiliser or only a cycad feed?
The title names Cycas revoluta, palm, and toddy palm. The target-species field says cycad, and the uses field says palm trees.
What dose is printed?
The title says the dry pack is enough for 20 litres after dissolving. No NPK percentages are printed. A field reads 20:1000.
How many reviews are in the capture?
One UK review, scored 5.0, with the body 'Yes' and the title 'Very good buy'. It does not describe a result on a plant.
COMPO's 1 litre green plant food is added to the watering can for green plants in a room, on a balcony, or on a terrace, and the coverage line also names palm trees indoors and outdoors. The listing states an NPK of 7+3+6 with trace nutrients and low chlorine, and the item-type line says EC fertiliser, which is wording on the listing rather than a medal. The amazon.co.uk star line is 4.6 from 11,119, and that star line is what maps to the highest score in this set, 86. In the file, one opened review is from the United Kingdom and calls it perfect with no further detail. The rest of the sample is from other countries, so the count is not a UK verdict on palms. Non-UK reviews describe stronger colour and new leaves on houseplants such as Monstera and spider plant, and one German review names oleander and angel's trumpet. The price is £26.45 on 19 October 2026. It is a general green-plant food that also names palms, and the English lines in the sample do not show a repeated leak or burn.
Pros
Cons
Best for: Mixed houseplants and a palm on the same watering round, when you want a printed 7+3+6
Less suitable: A buyer who needs UK reviewers describing palms, or a concentrate sold only for palms and cycads
Specifications
Common questions
Is this only a palm fertiliser?
The title is green plant food. The bullets say all green plants in the room, on the balcony and terrace. Coverage and target lines also name palm trees.
What NPK does the listing state?
Organic and mineral NPK fertiliser liquid 7+3+6 with trace nutrients, low chlorine, and the item type says EC fertiliser.
Are the 11,119 reviews from the UK?
The count is the amazon.co.uk star line. In the file, one opened review is from the United Kingdom and the rest are from other countries.
Miracle-Gro Shake 'n Feed Palm is an 8 lb (3.63 kg) bag of granules for palms, cycads, and tropicals, in the ground or in containers. The bullets name magnesium, iron, and manganese, claim a feed of up to three months, and claim no burn when used as directed. A field shows 8:2:12, which is not printed as a full NPK sentence in the bullets. The amazon.co.uk line is 4.6 from 1,301, and every review in the file is from the United States. Those reviewers describe pindo palms and Chinese windmill palms perking up. One reviewer found it was a case of shake and dig, not a surface sprinkle, and called the result only so-so around spiky plants. The price on 19 October 2026 is £97.15, far above the other packs. The listing's coverage is up to 300 square feet in the ground or 96 US gallons of container soil, which is an in-ground quantity.
Pros
Cons
Best for: Several in-ground palms when you want those named traces and accept the US reviews and the price
Less suitable: One house palm, or a first buy where £97.15 is the outlier in this set
Specifications
Common questions
What does the listing say is in the granules?
Bullets name magnesium, iron and manganese for palms, cycads and tropical plants, in the ground or in containers, and claim no burn when used as directed.
How long does it claim to feed?
The title says feeds up to 3 months. Coverage is printed as up to 300 square feet in the ground or 96 gallons of container soil.
Why is the price so far above the other packs?
The amazon.co.uk capture shows £97.15 for this 8 lb bag. The reviews in the file are from the United States, not the United Kingdom.
Espoma Palm-Tone is a 4 lb (1.81 kg) bag of dry granules, with 4-1-5 on the title, sold for palms and hibiscus, and the listing says no mixing is required. The amazon.co.uk line is 4.6 from 363. The reviews in the file are from the United States: palms described as looking healthy, hibiscus bloom as a repeated use, and yuccas turning a darker green. The complaint that comes up more than once is a strong smell. One reviewer called the 4 lb bag a bit pricey, and several reviews are about hibiscus rather than palms. A liquid-volume field reads 4 litres and conflicts with the dry bag, so treat the product as granules. The price is £29.64 on 19 October 2026. The maker's US application rates are not a UK trial.
Pros
Cons
Best for: An in-ground palm or a hibiscus when you accept US reviews and a dry 4-1-5
Less suitable: One kentia on a windowsill, or a buyer who needs a UK review sample
Specifications
Common questions
What analysis is on the title?
The title and bullets say 4-1-5. The listing calls it natural and organic and says it is formulated for palms and hibiscus.
What do the reviews complain about?
The file's reviews are from the United States. Repeated comments are a strong smell, the need to follow the instructions, and heavy use on hibiscus as well as palms.
Is the 4 litre field a liquid volume?
The product is a dry 4 lb bag. A liquid-volume field in the capture reads 4 litres and conflicts with that. Treat it as dry granules.
This pack is two 1 litre bottles of Palm Focus, mixed at the same 5 ml per litre as the 100 ml bottle, at £17.76 on 19 October 2026. Across 3,401 amazon.co.uk reviews at 4.5, the file's sample is from the United Kingdom. Reviewers report greener date palms, a Trachycarpus fortunei whose yellow fronds improved, and leaves showing more green, including on some Dracaena and rubber plants. One reviewer said date palms responded while indoor butterfly palms and parlour palms in the same household did not. Others saw little change and thought it needed longer. Someone with many palms in the ground found the liquid expensive and suggested a slow-release feed instead. No NPK is printed, and a field that reads 200:1 is not the same instruction as the 5 ml bullet. One UK review says to keep it away from your eyes.
Pros
Cons
Best for: Several container palms when you will measure 5 ml and want the volume
Less suitable: One small parlour palm, where 100 ml is enough to try and two litres will sit unused
Specifications
Common questions
What is in the pack?
Two 1 litre units. The listing unit count is 2,000 ml. The captured price is £17.76.
Did every palm in the UK reviews respond?
Reviewers report greener date palms, a windmill palm, and some other houseplants. One reviewer said indoor butterfly palms and parlour palms did not change.
Does the listing print an NPK?
No. It prints the 5 ml per litre mix. A separate field reads 200:1, which is not the same sentence as the bullet.
Thirty COMPO guano sticks go into a hole 5–6 cm from the stem and are then covered, with a claimed life of about three months. The listing says to use them every three months from March to October and not in winter, and to store them dry, above 6 °C and below 35 °C, out of sunlight. The amazon.co.uk star line is 4.5 from 2,853. The 50 reviews in the file are from France, Belgium, and Germany: houseplants described as growing faster, and a French note that the instructions were in German. English on the pack is not guaranteed. A field shows 11:4:8, which is not printed as an NPK sentence. The price is £15.78 on 19 October 2026. One Belgian note says the pack is used up quickly, and the effect is not instant.
Pros
Cons
Best for: A pot you already feed on a March-to-October stick cycle, if you can read the pack
Less suitable: A buyer who needs UK review texts or English instructions confirmed on the listing
Specifications
Common questions
When does the listing say to use the sticks?
Every three months from March to October, and not in winter. Storage is dry, above 6 °C and below 35 °C, out of sunlight.
Where do you insert a stick?
The bullets say 5–6 cm from the stem, then cover with soil. English on the pack is not guaranteed.
Are the 2,853 reviews a UK sample?
The star line is the amazon.co.uk figure. The review texts in the file are from France, Belgium, and Germany, not the United Kingdom.
This indoor-titled pack of 30 Jobe's spikes states 16-2-6 on the bullet, and you push them into the soil. Two UK reviews, inside a 4.5 from 46 on amazon.co.uk, say the spikes last and are easy to push in, and one calls them a winter pick-me-up for indoor plants on darker days. Neither review states a fault, so the file has no complaint pattern to quote. High nitrogen is a listing claim, not a reported burn. This is a different ASIN from the other Jobe's 30-pack: model 5101 and a captured weight of 70 g, against model 05101 at 20 g. The price on 19 October 2026 is the same £6.99. With only two review texts, 4.5 is not a large UK sample, and the bullets do not state how many months one spike lasts.
Pros
Cons
Best for: One indoor fern or house palm when you want spikes the title marks as indoor
Less suitable: A buyer who needs a large UK review sample or a label that names magnesium and manganese
Specifications
Common questions
What analysis does the bullet state?
The bullet says 16-2-6 and that the spikes provide high nitrogen levels. The title says indoor fern and palm spikes.
Are these the same listing as the other Jobe's 30-pack?
No. This ASIN is B018YI7SX6, model 5101, captured weight 70 g. The other pack is B000GD3KD0, model 05101, captured weight 20 g.
What do the UK reviews in the file say?
One review says they last and are easy to push in. Another calls them a winter pick-me-up for indoor plants. Neither states a fault.
Palm Focus 100 ml is mixed at 5 ml per litre for palms and cycads in pots or in the open ground. Across 454 amazon.co.uk reviews at 4.4, UK owners describe a garden palm looking better, a fan palm recovering from wilt and brown leaves, and new greener growth after a few weeks. One long-term user reported weekly feeding without yellowing or a burnt look. The 19 October 2026 capture does not print an NPK. Several reviewers call 100 ml a sample that runs out on a regular feed, and a Washington palm owner still objected to the price of the small bottle. Others saw no change yet, and one said browning continued. At £4.25 it is the smallest specialist bottle in this set, which suits a single pot and runs short if you water several outdoor palms.
Pros
Cons
Best for: One house palm or a first trial, if you will measure 5 ml per litre
Less suitable: Several in-ground palms that would empty 100 ml in a few waterings
Specifications
Common questions
How do you mix Palm Focus 100 ml?
The listing says mix 5 ml of Palm Focus in 1 litre of clean water. It does not print an NPK analysis in this capture.
Can this 100 ml bottle be used on outdoor palms?
The bullets say it is suitable for palms in open ground, pots, indoors or outdoors. The uses field also names cycad care.
Why do some reviews call the bottle small?
UK reviews in the file praise greener growth but several call 100 ml a small or expensive size for regular feeding.
These 30 Jobe's spikes are pushed into the compost, and the listing claims they feed ferns and palm plants for two months. Across 4,359 amazon.co.uk reviews at 4.3, UK owners report a large cycad, potted Canary palms putting on new green growth after a wet windy winter, and sad palms looking lusher over a couple of months. Several people had only just inserted the spikes and could not judge them, and others saw no difference on a palm or on tree ferns. The analysis sentence does not print percentages. A separate field reads 16:2:6, a high-nitrogen tilt if that is the figure you rely on. Indoor use is asked on the listing and is not answered as a spec. At £6.99 on 19 October 2026, reviewers in the UK sample call the price good value, which is why this pack is the best value here: a low shelf price, a large UK review count, and a score of 79, against a £97.15 bag at the other end of the set. Coverage on the listing is marked low, so the spikes suit a pot or a small plant rather than a whole border.
Pros
Cons
Best for: A pot or a small palm when you will not measure a liquid and can wait a couple of months
Less suitable: An in-ground hardy palm if you wanted a printed palm analysis with magnesium or manganese named
Specifications
Common questions
How long do these Jobe's spikes claim to feed?
The bullets say the spikes feed for 2 months. You insert them into the soil. Coverage on the listing is marked low.
Do UK reviewers see a quick change?
Some UK reviews report greener palms or a cycad doing well. Others say it is too soon to tell or that they see no difference.
Is an NPK printed in the analysis line?
The guaranteed-analysis bullet states 30 spikes per package and does not print percentages. A separate field reads 16:2:6.
UK GROW's 1 litre liquid is named for indoor palms, garden palms, and larger palm trees, and the bullets say to mix it with water. They do not give millilitres. A UK review says the product arrived with no mixing instructions. Three UK texts sit inside a 4.0 from 6: well packed and would use again, a short 'very good', and that missing-instructions note. No NPK is printed. The capture uses the same image URL, the same 4.0 from 6, and the same best-sellers line as the 5 litre ASIN. The price is £10.99 on 19 October 2026. You cannot take a dose from this file, so the bottle only helps if a rate is printed on the label in your hand.
Pros
Cons
Best for: Someone who already has a written rate for this nutrient and wants the 1 litre size
Less suitable: A first buy when you need a millilitre figure before you open the cap
Specifications
Common questions
How much UK GROW do you mix?
The bullets say mix with water and do not give millilitres. A UK review says the product came with no mixing instructions.
Which palms does the listing name?
The bullets say indoor palms, garden palms, and larger palm trees. They do not name a genus.
Is this the same bottle as the 5 litre UK GROW listing?
No. This ASIN is the 1 litre pack at £10.99. The 5 litre ASIN is B0CC2RSC11 at £19.99. The capture uses the same image URL and the same 4.0 from 6.
UK GROW's 5 litre palm liquid is the larger pack beside the 1 litre listing, and the capture shows the same 4.0 from 6, the same three UK review texts, and the same image URL. The bullets say a few diluted drops feed indoor palms, garden palms, and larger palm trees, and they do not print millilitres. A field reads 1:1. That figure is not a verified dilution: the bullets only say mix with water, and a reviewer said the product came with no mixing instructions. No NPK is printed. Captured weight is 5.2 kg and the price is £19.99 on 19 October 2026, which is less per litre than £10.99 for 1 litre. That saving only helps if a rate is already printed on a label you can read. Five litres is a large guess if the bottle in the file has no dose.
Pros
Cons
Best for: A household that already uses this nutrient at a rate printed on the label in hand
Less suitable: A first palm feed chosen from the listing text alone
Specifications
Common questions
Is 1:1 the mixing rate?
A field on the listing reads 1:1. The bullets only say mix with water. A review says there were no mixing instructions.
Who is the 5 litre pack for?
The bullets name indoor palms, garden palms, and larger palm trees. They do not give a measured dose or an NPK.
Why is the star count the same as the 1 litre listing?
Both captures show 4.0 from 6, the same best-sellers line, the same image URL, and the same three UK review texts.
Eleven amazon.co.uk listings were read from the pages captured on 19 October 2026. There is no laboratory test. Scores were already stored on each ASIN and map that star line, including the note that a high star count can sit on a thin or non-UK review sample. This page did not recalculate those scores. The top pick is the highest stored score. The best value is the £6.99 spike pack with a large United Kingdom review sample whose reviewers call the price good value. The cheaper 100 ml bottle was called small for a regular feed. A 5.0 from one review was not treated as value. The weights below sum to 100. They describe how the listings were read. They are not a second score.
Amazon star line
40%The stored score maps the amazon.co.uk star line in the 19 October 2026 capture. COMPO green plant food maps from 4.6 and 11,119 reviews to 86, the highest score. A 5.0 from one review maps to 80 and does not outrank that file. A high count can still sit on a thin or non-UK sample. That limit stays on the score. It is not a laboratory test.
Listing clarity
25%A printed dose, a printed NPK or a named trace, and a place line are what you can check on the listing. Palm Focus states 5 ml per litre. UK GROW's bullets do not give millilitres. A field that reads 1:1 or 16:2:6 is recorded as a field, not as a sentence the bullets print. An EC fertiliser line is listing wording, not a medal.
Review geography
20%Opened review texts count as a UK sample only when the file says United Kingdom. Jobe's fern and palm spikes use a UK sample at 4.3 from 4,359. COMPO's 11,119 and Miracle-Gro's 1,301 are not UK samples in the file. French, German and United States comments are not treated as UK opinion.
Shelf value
15%The best value is the £6.99 spike pack, score 79, with a large UK sample whose reviewers call the price good value. The £4.25 bottle of 100 ml is cheaper, and reviewers call that size small for a regular feed. The £97.15 bag is the outlier in this capture. One five-star review was not treated as value.
Match the plant, the dose and the season before you match the star line. Prices below are amazon.co.uk shelf prices on 19 October 2026. This is not a laboratory test.
Palm fertiliser on amazon.co.uk is a small set of liquids, spikes and granules sold for palms and, often, cycads or ferns. UK buyers are usually feeding a house palm or a hardy outdoor palm. The useful difference is a concentrate with a printed dose, or a general green-plant food that merely names palms. This page uses the 19 October 2026 amazon.co.uk capture. It is not a laboratory test, and it is not a market-size study. Start with the plant in front of you.
Hardy palms should not be fed in winter. Stop by late August so growth can harden. An all-year indoor habit does not transfer to a windmill palm in the ground. Nitrogen after September makes soft growth.
Several large amazon.co.uk counts in this set are reviews from the United States, France or Germany. Do not present those texts as UK opinion. A 5.0 from one review is not a result on a plant.
Cold soil, poor drainage and old leaves can yellow a palm. Iron and magnesium show on different leaves. Do not double the dose after a week, pile granules on the trunk, or cut off every yellow frond.
Name the plant first. A true palm, a cycad such as Cycas revoluta, and a fern sold on the same spike are not one plant. A sago is not a kentia. Then demand a dose you can measure. Palm Focus listings say 5 ml per litre. UK GROW's bullets say mix with water and do not give millilitres. A review in that file says the bottle arrived with no mixing instructions. A field that reads 1:1 is not a verified dilution. Liquids suit one pot if you will measure. Spikes suit someone who will not mix.
Hardy Palms says palms want magnesium, manganese and traces that cheap general feeds often lack. Miracle-Gro's bullets name magnesium, iron and manganese, and claim a feed of up to three months. Jobe's 16-2-6, where a bullet states it, is high nitrogen. A high-nitrogen tilt is a listing claim, not a reported burn. Where a ratio sits only in a data field, it is not the same as a printed analysis. Retailer pages for Palm Focus disagree on NPK, and the amazon files do not settle one figure.
Three typical situations, each with a recommendation from this comparison.
A kentia, parlour palm or areca in one pot needs a small measured liquid and a summer-only habit. Palm Focus 100 ml is about £4.25, mixed at 5 ml per litre, with 4.4 from 454 United Kingdom reviews. The capture does not print an NPK. Reviewers call 100 ml small once you feed regularly. It is a poor fit for several outdoor palms.
A windmill palm or dwarf fan palm in a pot or in the ground needs drainage, a measured dose, and a stop by late August. Palm Focus, two 1 litre bottles, is about £17.76 and uses the same 5 ml per litre, with 4.5 from 3,401 United Kingdom reviews. One reviewer said a Trachycarpus improved. Someone with many palms in the ground still found liquid costly. Do not copy an all-year indoor feed onto a palm in the soil.
Read the also-for line. A sago is not a kentia, and a fern spike is not automatically a palm analysis. Jobe's fern and palm spikes, 30 for about £6.99, are sold for ferns and palm plants. UK reviews mention a large cycad and potted Canary palms. The analysis sentence does not print percentages. A field reads 16:2:6. Indoor use is asked on the listing and is not answered as a spec.
The top pick is COMPO green plant food 1 litre at about £26.45. It has the highest stored score, 86, from 4.6 and 11,119 reviews, and the listing prints an NPK of 7+3+6 with trace nutrients. You add it to the watering water. The opened reviews are mostly outside the United Kingdom, so the count is not a UK verdict on palms. The best value is Jobe's fern and palm spikes at about £6.99, score 79, from 4.3 and 4,359 United Kingdom reviews. Reviewers in that sample call the price good value. The £4.25 bottle is cheaper and is described as small for a regular feed. A 5.0 from one review was not treated as value. None of these scores is a laboratory test.
Jobe's fern and palm spikes
About £6.99, score 79, from 4.3 and 4,359 United Kingdom reviews. Reviewers in that sample call the price good value.
