Pruning advanced ornamental trees. Now's the time... Generally speaking an ornamental tree is one that is grown for its decorative looks and not for food. Winter is the perfect time to prune deciduous ornamental trees, as their structures are dormant. Inside the tree though, important processes are underway.
