Yes, there is clearly no sense of urgency at all - at this rate they will be too late for (sensible) tree planting this spring.
One small correction. "ARE too late" .
You can plant trees at any time of year. However, the risk of transplant shock killing the tree is substantially higher when in a non-dormant state.
Basically post-leaf out, prior to colour-change/leaf fall.
Further, any nut-bearing species don't do as well w/fall transplants (think Oak); (neither do Conifers, but the City rarely plants those on/near streets.
At this point they will either non bother to plant till fall; or they will plant and rely on the standard 2-year warranty for new trees they build into most contracts; though only periodically enforce.
