Pruning Conifers and Broad-leaved Evergreens
Vince Marrocco
Chief Horticulturist, Morris Arboretum

Evergreens, more than any of the other plant groups, can be seriously disfigured or destroyed by careless pruning. For this reason, it is important for the landscape professional or homeowner to understand when to prune and where to place pruning cuts. The morning session will be a lecture and demonstration. The afternoon session will feature supervised, hands-on pruning. Please bring a hand pruner and small pruning saw for the afternoon session. This course carries 4.5 CEUs for ISA certified arborists (S=1, P=2.5, M=1).
