re: Lawn type and lawn maintenance questions

That is fescue or perennial ryegrass both of which are common in that area and look similar. I think it is fescue. It is common to overseed with more seed once a year or so to get the thick stand you want. You can over seed now with a turf type fescue. (Do not buy coated seed--seed companies are using the coating to lower their cost. They are replacing weight in the bag with the coating--some are as much as 50%).

Fertilizer in the spring and summer but I would not now given how late it is.

There are lots of weed control products. I would wait to spring on that too. You will likely get a frost there before the end of October and most of your weeds will not survive it.

Don't mow as short as you would bermuda grass.
