Garden sieve mesh size determines how fine the screened material is, with common apertures ranging from about 6 mm to 12 mm. A finer mesh around 6-8 mm suits seed-sowing and potting compost, while a coarser 10-12 mm mesh is better for general soil and gravel. Choosing the mesh depends on how fine you need the end result.

Yes, garden earth sieves are typically made from galvanised steel or tough plastic, making them weather-resistant and durable for repeated outdoor use. Galvanised steel mesh and frames resist rust and hold their shape under the weight of wet soil. This lets the sieve stay outdoors and handle heavy screening without bending.

To use a soil sieve, rest it over a wheelbarrow, bucket or frame, add a few shovelfuls of soil, and shake it back and forth so the fine material falls through. Work in small batches to avoid clogging the mesh and to keep the sieve manageable. Break up clumps by hand and discard stones and roots left on top.

Most garden sieves are around 35-40 cm in diameter or width, which lets them rest across the top of a standard wheelbarrow or bucket. A round riddle typically spans a barrow's opening, while rectangular sieves may have edges or lugs to hook over the rim. Check the sieve's dimensions against your barrow before use.
