My grandmother never took a rosemary cutting without tearing off a little heel of old wood: I laughed for years before I understood why she was right
Your grandmother wasn’t being fussy when she tore off that tiny scrap of old wood with rosemary cuttings—she was tapping into the plant’s natural rooting hormones. That small heel of bark exposes the cambium layer, where growth cells concentrate, giving cuttings a biological advantage that transforms propagation success. It’s a technique that works so well, you’ll wonder why you ever tried it any other way.
