We have a customer asking if we can roll her lawn to flatten out all the mole hills that popped up over the winter. We think the moles are gone (they had to go through another company for that, since we don't offer pest control yet), so it's just the residual damage. We're not sure right now if it makes more sense for us to do it (we'd have to rent a roller, since we don't own one) or to just refer her to another company who does rolling regularly, but either way, we'd like to educate her on lawn rolling before we touch her yard, or let someone else do it. We have an interest in her lawn's health too, since she's one of our weekly mowing customers. We know it causes soil compaction, so the lawn would need to be aerated and seeded afterwards to keep it healthy. What else should we know?
