==Own-root fruit trees==
Many species of fruit, e.g., [[ficus|fig]], [[olive]], and [[pomegranate]], are commonly grown on their own roots, as there may be no great advantages to using a special rootstock, or suitable rootstocks may not be readily available. However, even for fruit trees that usually are grown grafted on a rootstock, there can be advantages in growing them on their own roots instead, particularly in the traditional [[coppicing]] systems advocated in both [[sustainable agriculture]] and [[permaculture]]. Disadvantages of using own-root trees can include excessive size and excessive production of wood (thus very long times until the start of fruit production), although training branches horizontally and limiting pruning to summer only may help encourage fruit production at an earlier age.<ref>{{cite web |url=https://www.youtube.com/watch?v=fiHQU_p8rCY |title=Phil Corbett video |publisher=Youtube.com |access-date=2012-09-26 |archive-url=https://web.archive.org/web/20160502015543/https://www.youtube.com/watch?v=fiHQU_p8rCY |archive-date=2 May 2016 |url-status=live }}</ref><ref>{{cite web |url=http://www.orangepippin.com/articles/own-roots |title=Orange Pippin apple and orchard resource |publisher=Orangepippin.com |date=1981-04-16 |access-date=2012-09-26 |url-status=dead |archive-url=https://web.archive.org/web/20100612223140/http://www.orangepippin.com/articles/own-roots |archive-date=12 June 2010}}</ref><ref>{{cite web |url=http://www.cooltemperate.co.uk/own_root.shtml |title=Phil Corbett website |publisher=Cooltemperate.co.uk |access-date=2012-09-26 |url-status=dead |archive-url=https://web.archive.org/web/20120518004546/http://www.cooltemperate.co.uk/own_root.shtml |archive-date=18 May 2012}}</ref> There is a lack of research on the use of the own root method in large-scale systems.  British horticulturalist [[Hugh Ermen]] was a prominent advocate of own root fruit trees, particularly apple trees, following his work at the Brogdale research centre in Kent.<ref>Whitefield, Patrick, 01/10/2011, The Earth Care Manual, Permanent Publications, p254, {{ISBN|185623021X}}</ref> The research undertaken at Brogdale did not continue but there has been renewed academic interest in own root fruit trees since the turn of the century.<ref>Thorpe, David, 13 November 2014, The One Planet Life: A Blueprint For Low Impact Development, Taylor and Francis, p376, {{ISBN|9781317625902}}</ref>
