Dr. Russell Sharp explains root cuttings — what they are, which plants respond well (eg. sassafras, paulownia/foxglove trees, aralia, clematis, hops), and why they’re useful for removing pests or reverting mature plants to juvenile growth.
He also gives practical tips: when to plant vertically or horizontally, why you should avoid rooting hormones, risks like loss of variegation and reduced hardiness in the mother plant, and why root cuttings could be a game‑changer for hop propagation.
