These data and R scripts were produced for the report entitled: "Factors affecting the vegetative propagation of ash<i> (Fraxinus excelsior </i>L.<i>) </i>from semi-hardwood and hardwood cuttings" - DOI: 10.1007/s11056-025-10103-y published in New Forests. This study was conducted as part of the Living Ash Project, which was funded by Defra. We tested the effects of stock plant age, mycorrhiza, rooting hormones, timing and substrate type on the rooting of ash cuttings in order to optimize current propagation techniques.
