Long handled patio weeder: what to check before you buy
Updated: October 2026
You are standing on a drive that greens up in the joints every spring, and the listing in front of you shows three heads, a star rating, and almost nothing you can measure. A long handled patio weeder is worth buying when the head can enter the joint you have, and the pole is long enough that you can stay on your feet. The four amazon.co.uk sets are lined up in the [long handled crack weeder comparison](/hub/weed-control/long-handled-crack-weeder). Prices and stars are the amazon.co.uk listings as checked on 19 October 2026. A qualifying purchase can earn us a commission at no extra cost to you.

What you are actually buying
Three tools share this search, and they do not clean the same crack. A block-paving knife is one stainless hook on a hardwood handle. Burgon & Ball states a 150 cm handle and a 7 cm head with a 90 degree edge, at £31.99 on the maker’s page, with a lifetime claim. A telescopic hook is the short end of the same idea. The Hardys tool at diy.com runs from 695 mm to 960 mm and was £11.77, with a foam grip and no note on how wide a joint it enters. A multi-head set puts a V-shaped wire brush and one or two scrapers on screw-together stainless poles. That third type is the whole kept Amazon set: two Anwor listings, the ADLUH set, and the GREELIX set.
Counting heads will not tell you which one fits. Three heads on a pole that bends are not an improvement on one knife that enters a joint of about 3 mm. A claw weeder, a Dutch hoe, and a spinning electric brush appear in the same results and are different products. If the title says patio and the picture is a lawn claw, leave it.
Length you can stand with
A standing weeder, among the tools that publish a figure, is about 1.4–1.6 m. Burgon & Ball states 150 cm. DeWit’s groove cleaner, via Crocus, is 140 cm. Both Anwor sets state 150 cm, and their bullets say the four stainless sections adjust from 17 inches to 60 inches. That figure is the assembled pole. It is not a promise that the head will sit in the joint when the pole is fully out. One Anwor review said the full length gave the wrong angle, and the head was easier in the hand.
ADLUH prints a packed size of 43 x 15 x 5 cm. That is the parcel, not a standing reach. GREELIX prints 1 x 1 x 1 cm in the technical table. That number is not a length you can stand with. If a listing will not state an assembled length, treat the pole as unknown. A telescopic pole that stops at 960 mm leaves you bent over a drive. It is the wrong end of the market if you are shopping because you cannot kneel.
Head, joint and stone
Concrete block joints are often about 2–5 mm. A slim 90 degree knife can enter a gap in that range. A thick L-scraper often cannot, which is what UK reviews say about the ADLUH and GREELIX scrapers. On those sets the brush is the head people keep using. The Royal Horticultural Society treats the knife and the angled wire brush as two jobs. The knife severs and levers growth in the crack. The brush scrubs moss, seedlings and debris.
The Anwor brush is brass on a wooden head. The GREELIX brush is copper-plated wire. Universal Paving says not to use a wire brush on Indian sandstone, because wire scratches and can leave metal that rusts. None of the four sets offers a nylon head. A resin or polymeric joint should not be routed out with a scraper at all. WRTAH01 reviews say you need an Allen key. The £16.99 Anwor uses a bolt, and one review says that bolt is a nightmare if you have arthritis.
What to pay
These are shelf prices on 19 October 2026, not a market survey, and they move. ADLUH sits at £11.99 (4.0 from 117 reviews) and GREELIX at £10.99 (3.8 from 123). The Anwor 3 Weeder Tools set is £16.99 (4.3 from 154) and Anwor WRTAH01 is £19.99 (4.2 from 466). Named single knives cost more: Burgon & Ball at £31.99, and Draper 29929 at £35.98 on the maker’s site, with other UK sellers nearer £25–£28.
The £19.99 Anwor is not a different class from the £16.99 Anwor. You pay about £3 more for a larger review file, and you still get an Allen key rather than a rivet. The £10.99 GREELIX is not a cheap version of a 150 cm knife. A crack weeder has no pesticide authorisation. Glyphosate’s approval in Great Britain, extended to 15 December 2026 while renewal is assessed, is not a ban and not a reason to spray off the label.
Common questions
How long should the handle be if I want to stand?
Look for a published length of about 1.4–1.6 m. Burgon & Ball states 150 cm, and both Anwor listings state 150 cm, with bullets of 17–60 inches. A telescopic hook that stops around 960 mm, such as the Hardys, will still bend you at the waist on a drive. ADLUH’s 43 cm and GREELIX’s 1 cm figures are pack or table lines, not a standing reach.
Is a three-head set better than one knife?
Only if you need a brush and a scraper in the same box, and the joint is wide enough for the scraper you were sent. A slim knife is the better single tool for a concrete joint of about 2–5 mm. A set wins when moss on hard concrete is most of the job and you accept a bolt or an Allen key. More heads do not repair a pole that bends.
Will a brass brush mark sandstone?
It can. Universal Paving advises against a wire brush on Indian sandstone, because the wire scratches and can leave metal that rusts. Brass and copper-plated wire are still wire. None of these four sets includes a nylon head. Try a nylon or polypropylene brush on an unseen corner before you buy a wire head for sandstone.
What is a fair price in pounds?
About £11–£20 is the band of the four Amazon sets checked on 19 October 2026, from GREELIX at £10.99 to Anwor WRTAH01 at £19.99. A named 150 cm knife is higher: Burgon & Ball at £31.99, Draper 29929 at £35.98 on the maker’s page. A telescopic hook near £12 can be fair for a short path. It is poor value if you needed to stand.
Does the listing length include the head?
Read it as the assembled pole the page is willing to state, and then check the bullets. On the Anwor sets the dimension line is 150 cm and the bullets say 17–60 inches across four sections. That is close, not a second product. It still does not tell you the angle the head will make in a narrow joint. One review found the full pole awkward and used the head by hand.
Should I ignore a tool that does not state an assembled length?
You should not treat it as 150 cm. ADLUH states a packed size only. GREELIX states 1 x 1 x 1 cm, which is not usable. You can still buy one if the brush is all you need and you accept the review notes on bending and loose blades. If standing without guessing is the point, stay with a listing that prints a length.
