I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
You can either sod or seed the areas. I suggest if they are extensive throughout the lawn you try seeding but if there are not that many try sodding. Now is a great time to do either seeding or sodding.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
