We pick up big limbs or debris and spray round up as necessary. It all depends on what the customer wants. Most of my beds are pine straw and we will spread fresh straw 1-2 times a year in a lot of them.
Going into 2013 I am going to offer a few levels of service in hopes of keeping things simple....
1. basic mow blow go
2. Add beds- weekly pick up of sticks and pine cones, blow out leaves, more attention to weeds, etc
3. Add pruning as needed
I'm just trying to find a simple formular to price the bed work. I would think in my area that we could do an extra 10 minutes on each lawn to accomplish good bed maintenance. 10 minutes might be high over the course of a year but would account for leaves.
