Sometimes vulgar cognition , what everybody know to be honest , just is n’t .   That ’s the vitrine , I ’ve feel , with much of the loosely accept data about companion planting .

Where does such data come from ?   That ’s what I began to wonder a number of geezerhood ago .   Why should tomatoes wish basil ?   Typically , the sharer of this data could n’t say .   I move to organic gardening literature , which usually just acquaint the companion planting combinations as fact .   By comparing many different explanation of companion planting , however , I finally identified a rootage .   A number of the books credit Ehrenfried Pfeiffer as an originator of companion planting know - how .

And if so , is the smell reciprocated ?   ( By Castielli – Own workplace , CC BY - SA 3.0,https://commons.wikimedia.org / w / index.php?curid=7133704 )

A trip to the New York Botanical Garden Library reveal who this inscrutable authority was .   Ehrenfried Pfeiffer was a German immigrant who was a disciple of Rudolf Steiner , a late 19thcentury , other 20thcentury Austrian philosopher and mystic .   Among other activity , Steiner founded biodynamic gardening .   Pfeiffer was one of only a fistful of people that Steiner entrusted with making his biodynamic “ preparation , ” such as preparation # 502 which call for milfoil blossoms to be gourmandize inside the urinary vesica of a red deer and exposed to the sunlight over the summertime , then buried over the winter before being disinter and used to inoculate the compost wad .

At Steiner ’s behest Pfeiffer also developed a procedure he called “ raw crystal . ”   In this process Pfeiffer would mix some biological extract with a solution of cop chloride and pour out the result into a petri dish antenna to observe the approach pattern of crystals that formed as the liquid state evaporated .   He applied this process for the most part to the survey of plant .   If the flora excerpt contributed to a unclouded and orderly pattern of crystal , Pfeiffer judge this to be a augury the plant was healthy .   If the blueprint was unclear or disorganized , Pfeiffer took this as cogent evidence that the plant was unhealthy .   When two plant infusion were combined with the Cu chloride solution , an attractive pattern was test copy that the plants were compatible and should be grown together .

Pfeiffer published his observations as a associate planting list .   Picked up and endorsed by J. I. Rodale , an other leader of the American constitutional horticulture movement , this list of supposedly compatible plants became a popular tool of constituent gardeners , who usually did not know of the nature of its parentage .   Passed down from Scripture to al-Qur’an , Pfeiffer ’s doubtful findings are still exclaim as gospel today .

Does this think that all fellow planting information is bastard ?   Not at all .   There are people who have pursued a more science - based take on this subject .   I ’ve interview one of them , Robert Kourik , on a podcast at thomaschristophergardens.com .
