A reputable company should give you detailed aftercare instructions, including mowing instructions, watering tips, and what to look out for. They should also have a number and email where you can reach someone if you have an issue. At Blades of Green, we have not only both of these but also a texting feature.
It is a huge red flag if you are told that your lawn does not need special care after service or that you can continue to care for it as you did before. Proper watering and mowing are critical to the success of your aeration service.
