Mulch is a protective cover placed over soil. Mulch material includes leaves, cardboard, and wood chips. These absorb rain, reduce evaporation, provide nutrients, increase soil organic matter, create habitat for soil organisms, suppress weed growth and seed germination, moderate diurnal temperature swings, protect against frost, and reduce erosion.<ref name="agroforestry"/> [[Sheet mulching]] or lasagna gardening<ref>{{cite web |last1=Toensmeier |first1=Eric |title=Sheet Mulching in 9 Easy Steps |url=https://www.permaculture.co.uk/articles/sheet-mulching-in-9-easy-steps/ |website=Permaculture.co.uk |date=24 November 2022 |access-date=18 October 2023}}</ref> is a gardening technique that attempts to mimic the leaf cover that is found on forest floors.<ref name="agroforestry">{{cite web |date=3 September 2011 |title=Sheet Mulching: Greater Plant and Soil Health for Less Work |url=http://www.agroforestry.net/pubs/Sheet_Mulching.html |url-status=dead |archive-url=https://web.archive.org/web/20021210053204/http://www.agroforestry.net/pubs/Sheet_Mulching.html |archive-date=10 December 2002 |access-date=21 October 2011 |publisher=Agroforestry }}</ref><ref>{{Cite journal |last1=Stratton |first1=Margie Lynn |last2=Barker |first2=Allen |last3=Ragsdale |first3=James |date=April 2000 |title=Sheet composting overpowers weeds in restoration project |journal=BioCycle |volume=41 |issue=4 |page=57}}</ref>
