If you have heavy clay soil in your garden, you may find it hard to dig, slow to drain and quick to compact. But rather than seeing it as a problem, you can turn it into a productive, workable garden bed by improving its structure \u2014 by adding organic matter, mulch and encouraging worms and other soil life.<\/p>\n\n\n\n

Why organic matter & mulch help<\/strong>
Clay soils are rich in nutrients but the fine particles make them heavy, slow to warm, and easily compacted. BBC Gardeners World Magazine+1<\/a>
Adding well-rotted compost, leaf mould, farmyard manure or other organic matter helps bind the clay particles into more crumb\u2010like structure, improving drainage and aeration. Ideal Home+1<\/a>
Mulching with organic matter helps retain moisture, moderate soil temperature and suppress weeds \u2014 and over time that mulch breaks down and adds deeper into the soil. GardenAdvice.co.uk+1<\/a><\/p>\n\n\n\n

Encouraging worms & biology<\/strong>
Worms are nature\u2019s soil engineers. They tunnel through heavy soil, bringing air and drainage, and their castings improve soil structure. By adding organic matter and keeping the surface covered with mulch, you encourage worm return and activity. (No-dig gardening practice emphasises this) Wikipedia<\/a>
As the mulch breaks down, it becomes part of the soil, increasing organic matter percentage and making the clay easier to work. RHS<\/a><\/p>\n\n\n\n
