I moved into a house a month ago, and am trying to recover the lawn. There are several patches (roughly a square foot each) with no grass at all, just tough soil. There are two large maple trees, so it is quite shaded. Possibly the previous owners had a dog. Possibly the big trees are sucking all the moisture out of the lawn. Not sure what the cause of the bald spots is.
I see a lot of information saying reseeding should happen in the spring or fall, but is it possible to reseed these patches with something now to promote growth?
Not sure what type of product would be best, if I should be reseeding or aerating, what time of year would be best, or if it's all a lost cause. (I hope not!) I live in Northern Ontario, so in a few months, the lawn will likely be covered in snow.
