Abstract Background and aims Soil bio-engineering using vegetation is an environmentally friendly solution to stabilise soil slopes. This study investigates tensile strength, Young’s modulus, and root diameter relationships for establishing woody perennials. Methods Specimens of ten woody European shrubs and small trees were transplanted into sandy loam soil to establish for six months. Root tensile strength and Young’s modulus were measured as well as the root length-diameter distribution. The effect of root water status on root diameter was evaluated for Scotch Broom. Results More than half of the root length for all species was thinner than 0.5 mm diameter. Typical tensile strengths were 2 values 17%–64%). Root diameter, investigated for Scotch Broom, depended strongly on root water potential and root water content by mass. Root water content could influence considerably the calculations of tensile strength. Discussion and conclusion Root tensile strength-diameter relationships often do not follow a negative power law, and depends strongly on taxa. Young’s modulus was strongly related to tensile strength of roots for certain species. Water status of roots strongly influences root diameter and hence strength and Young’s modulus properties, and must be controlled carefully in experiments.
