One nice thing about commercial contracts is that it's up to us to take care of all bed maintenance unless the homeowners at an HOA ask us to leave it alone.
We've been plugging away at cutting down black eyed susans, daylillies, hostas, astilbe, etc, over the last month. We'll be working on cutting down ornamental grass next week and should be done by Thanksgiving.
We just kinda do a little every week as we have time.
Maybe not the best, but it kinda depends on the customer and budget constraints.
