Hi all! I would like to plant grass in our back yard that has several
trees. It gets some sun, but not much, it's usually shady during the
day. I would like your expert advice on the following issues:

Some sun but not much leaves you with fescues if you're going to stick to
true grasses. You've got a lot more latitude if you choose another
groundcover. See what the code actually says.

Fall is actually the best time to plant grass, either seed or sod.
How wierd do they get? I'd be inclined to toss out some cheap
covercrop like buckwheat now, plead crop failure, and replant with
what you actually want in the fall. There's a fair chance you'll
be replanting then anyhow if you're not meticulous in watering.

Yes, you'll need a sprinkler of some sort, either for seed or sod.
If you want to put in a sprinkler system, you won't have to drag around
hose and sprinklers every day or two until the grass is established.
