Bentgrass is not a grass or turf species that is desirable in home lawns. This winter has been hard on a lot of bentgrass patches in lawns. Here is one where the entire patch of bentgrass has turned brown. If
If your lawn is showing a great deal of bentgrass that has winter killed, you may want to take this opportunity to give it a hard raking to get rid of the dead stems and to thin out the unwanted bentgrass. Then add some soil and a high quality grass seed mix. This will thin out the bentgrass for a while. Be forewarned, however, that there will likely be enough bentgrass left that in a few years it will be back as thick and strong as ever.
