The Faithfull Countryman Garden Sieve has an all steel construction. It provides a simple method to help improve soil quality by allowing the gardener to filter through soil, to remove stones, twigs, large lumps of clay and other foreign objects to produce a finer soil (tilth). Sieves help keep compost and potting mixtures pure and clear of unwanted objects, helping your seedlings to thrive and achieve maximum results from your compost and soil.
