Best garden riddle
Updated: 21 October 2026
You want a best garden riddle, and the highest star line in the set is not the tool for a compost bin. A 4.7 can be a pair of scoops. A best-seller rank can be a 20 cm pan. The useful question is which job you are doing, and who should skip that pick. Prices and stars are from the amazon.co.uk listings in the [compost sieve comparison](/hub/raised-beds-greenhouses-and-compost/compost-sieve), checked on 19 October 2026 by Peter F.

No single winner
Star count and the job in the garden are different scores. The Spear & Jackson fixed riddle is 4.6 from 1,806 reviews at about £14.95. The Haxnicks folding riddle is 4.2 from 411 at about £9.99. The KOOLPUG insert sieve is 4.5 from 388 at about £24.99. The two stainless scoops are 4.7 from only 25 reviews at about £9.99. None of those numbers, on its own, names the right mesh. KOOLPUG’s own shop showed £22.99 when we noted it. Use the amazon.co.uk price. Diameter and material are on the garden sieve buying guide.
One compost bin
For one bin, a fixed mesh around 10 mm is the straightforward pick if you only need that grade. The Spear & Jackson riddle is the top pick: chrome-plated steel, 586 g, 10 mm square holes, and no insert to lose. Reviews describe holes of about 1 cm and say small stones can pass. The bullet says 315 mm, the technical line says 31.5 cm, and the maker’s page says 330 mm and a 10-year guarantee. Do not merge those diameters. Skip it if you also need 3 mm or 6 mm the same afternoon.
Choose the Haxnicks Easy Riddle when 250 g and folding matter more than a rigid plate. It is listed at 40.5 × 31 × 24 cm. The amazon listing does not print a millimetre size. Haxnicks’ page states 10 mm × 10 mm. Skip it for sharp stone.
Stones in topsoil
Stony topsoil wants rigid metal, not poly mesh and not a 3 mm pan. A 10 mm plate lets pea gravel through and holds the larger stones. The Spear & Jackson riddle does that job and cannot swap to a finer disc. A fixed 3 mm stainless pan, 30 × 6 cm at about £12.99, is 4.1 from 79 reviews. Reviewers call it fine, and one says it bends. That pan is a poor stone riddle. If you want more than one grade, use a metal insert set and fit the coarse disc first.
Several grades in one shed
Three or five meshes are worth it when you will change grade. The KOOLPUG sieve gives 3, 6, and 12 mm on a 30 cm frame at about £24.99, with crossed rods. UK reviews praise the rods and say the insert falls out when the sieve is tipped. One buyer received two inserts, not three. One line says 740 g and another says 550 g.
The best value is the ADEPTNA five-mesh pan at about £14.95, 29.5 cm and 890 g, 4.5 from 40 reviews, covering 3 mm through 12 mm. One UK review says the inserts fit snugly. Another says the smallest was about 5 mm rather than 3 mm and that wires buckled. The Flatro frame at the same price is 4.6 from 28 reviews, and two reviews call it a bit flimsy. Forty reviews are not 388.
Leave these off the shortlist
Do not crown the Armo pan because a rank called it popular. It is 20 cm, 3.4 from 109 reviews, and the title says large. That is a lawn-patch tool if 20 cm is what you measured. The two scoops are 3.8 mm and 5 mm mesh shovels with 25 reviews, also sold for cat litter. They are not a frame. Do not crown the LIROPAU listing because a crank looks faster. It is about £52.99, 2.0 from two reviews, and 5 kg. Storage against a hand riddle is on the rotary soil sieve versus riddle page.
Common questions
What is the best compost sieve for one bin?
If one mesh is enough, the Spear & Jackson riddle at about £14.95 is the clearest match in this set: fixed 10 mm holes and 4.6 from 1,806 reviews. Small stones pass that plate. If you want a light sieve that folds, the Haxnicks Easy Riddle at about £9.99 has 4.2 from 411 reviews, and you should skip it for sharp stone. Neither is the best riddle in Britain. Each is a fit for one bin, with that limit.
What if the soil is full of stones?
Use rigid metal and a coarse grade, about 10–12 mm, rather than poly mesh or a 3 mm pan. The Spear & Jackson plate is the simple version. An insert set such as the KOOLPUG, with a 12 mm disc, can do the same job if the disc stays in the frame. Reviewers on that listing say it can fall out when you tip the sieve. A 3 mm mesh will clog and is the wrong first screen for flint.
Is the highest star rating the one to buy?
The highest star line here is 4.7 from 25 reviews, on two scoops that are not a riddle. The longest review line at a high rating is the Spear & Jackson, 4.6 from 1,806, for a single 10 mm grade. Name the job, then the type, then who should leave that type on the shelf.
When is a folding riddle enough?
A folding poly-mesh riddle is enough for light, dry compost, when 250 g and a flat pack matter. That is the Haxnicks case, and the maker states 10 mm × 10 mm even though the amazon listing does not. It is not enough for rocky soil. Reviews include mesh torn within a day and mesh that failed after about a year. Treat those as a reason to skip it for stone, not as a timed lifespan.
When are three meshes worth the extra pounds?
They are worth it when you will use more than one grade. The KOOLPUG at about £24.99 has 388 reviews and a fall-out complaint. Five-mesh pans at about £14.95 cover 3 mm to 12 mm on a shorter review line, and one ADEPTNA frame at that price has discs that reviewers say slip. Pay the extra only if the grades match work you actually do. A single 10 mm plate is the better buy for one repeated job.
