Tree work is highly visible, so a large removal is noticed by the whole street. A professional-looking crew, plus a simple card for the nearest four or five houses noting you are working locally this week, converts that attention into more jobs on the same street.
Tree work clusters geographically more than almost any trade, and most companies capture almost none of that clustering.
The reason it works is visibility. A crane or a bucket truck in a front yard is a public event. Everyone on the street sees it, everyone driving past sees it, and a proportion of them have a tree they have been worrying about.
Three things convert that attention:
Do this systematically after every large removal rather than occasionally. One visible job on a street should produce more work on the same street, and that work carries no acquisition cost and minimal drive time.
The clean-yard finish matters here too, because the neighbours see the site after you leave.
