How can a dirt or excavation business add recurring services instead of one-off jobs?

Depending on your climate watering plants and grass, dead heading plants and bushes, trimming, garbage clean up could be ways to sell a recurring service.

One thing I like to keep in mind is once you are in front of a customer at their home, if you have other skill sets you can offer them and they trust you, you can get yourself into a lot of different revenue streams. Even teaming up with other trade professionals so you have a lot of different people out promoting you and your work, and you are out doing the same for them.
