The use of non-dormant rods as planting material: A new approach to establishing willow for environmental applications

In this trial we tested a new planting technique for willows used in environmental applications such as green structures in urban settings. Three commercial willow clones were planted in spring 2008 at different periods as non-dormant woody rods. Comparing the main growth parameters at the end of the season, we found that planting date may affect plant establishment depending on the clone. Based on our results, the use of non-dormant willow material collected and planted in spring is possible in our environment with several different clones. Best results were obtained with Salix viminalis (Sv 5027), which can be planted with a delay of about one month without showing any significant decrease in biomass production or survival rate.
