Some, such as Aztecium and Geohintonia, take this to an extreme, apparently growing in a decomposing limestone or gypsum soil exclusively. What is not clear is whether they \"require\" this in order to flourish or are just better able to tolerate the conditions than other species, such that in their native habitat they survive where others perish. What does appear to be clear in greenhouse cultivation is that many cacti do not do well in acidic composts and do appear to benefit from some added limestone in the compost (limestone, NOT lime).\u003cbr data-mce-fragment=\"1\"\u003eTo this end, adding some granular limestone or limestone chips (3-5mm) to your compost and avoiding peat-based composts for some species, is generally accepted to be of benefit.","brand":"planetcactus","offers":[{"title":"Default Title","offer_id":45333543289139,"sku":"","price":5.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/1911\/8899\/files\/il_fullxfull.3109846154_g4v2.webp?v=1686185274","url":"https:\/\/www.planetcactus.ca\/products\/crushed-limestone-1-8-1-4-1kg","provider":"Planetcactus ","version":"1.0","type":"link"}
