{{further|Herb spiral}}

[[File:Kräuterspirale.JPG|thumb|A [[herb spiral]] provides varied conditions in a small space for multiple species to grow together.]]

Space can be saved in permaculture gardens with techniques such as [[herb spiral]]s which group plants closely together. A herb spiral, invented by Mollison, is a round cairn of stones packed with earth at the base and sand higher up; sometimes there is a small pond on the south side (in the northern hemisphere). The result is a series of [[microclimate]] zones, wetter at the base, drier at the top, warmer and sunnier on the south side, cooler and drier to the north. Each herb is planted in the zone best suited to it.<ref>{{cite web |last1=Engels |first1=Jonathon |title=The Magic and Mystery of Constructing a Herb Spiral and Why Every Suburban Lawn Should Have One |url=https://www.permaculturenews.org/2015/04/17/the-magic-and-mystery-of-constructing-an-herb-spiral-and-why-every-suburban-lawn-should-have-one/ |website=Permaculture News |publisher=Permaculture Research Institute |access-date=9 September 2023 |date=17 April 2015}}</ref><ref>{{cite web |title=Advantages of an Herb Spiral |url=https://theherbexchange.com/advantages-of-an-herb-spiral/ |website=The Herb Exchange |date=12 July 2018 |publisher=The Growers Exchange |access-date=9 September 2023}}</ref>
