The role of an Arborist often involves knowing and using expertise in the areas of pruning, planting and tree selection. This workshop will start with nursery practices, learning about new tree cultivars and choices for various environments, in particular street planting.
Many of the challenges we face with older trees, and many of the structural failures seen on trees of all ages, may be prevented by proper training and pruning when they are young. This preventive care and maintenance will help trees in the urban forest remain healthier, more productive, and safer for the people who live around them. Further, investment in structural training of young trees means far less costly measures will be necessary to maintain a tree properly as the tree becomes mature. The reduction of risk and liability associated with poorly structured trees is, in itself, an excellent reason to begin and maintain a structural pruning program for young trees in an urban area.
We will review proper pruning practices and the components of strong tree structure, how to remove or reduce potential risk factors through pruning, and developing a multi-year pruning program for young trees. On a walk through Urban Forest Nursery, the progression of pruning and structural training on different species of trees over a 3-year span will be discussed.
Lessons from the nursery: How trees are selected, planted, pruned, staked and harvested for landscape use
Expanding your tree planting palette: See up close and personal many of the new tree cultivars that will become new favorite choices for street tree use. Consider outstanding alternates for the overused ash and maple varieties, trees with great form, characteristics, limited mature size, less aggressive roots, great fall color and minimal insect and disease challenges.
Structural pruning of small trees: Learn how to prune trees in their early years after transplant to maintain structure and balance into the future.
Planting container grown nursery stock: Learn how to deal with root issues during planting to help ensure tree success.
