Seed box on an old grain drill, with a lb of timothy or three lbs meadow fescue and some legume. Ladino persists the longest on low ground, BFT is second choice, Kura is unavailable.
Usually spring, but really wet spots many not work until August.
High or low ground, but it competes better on low ground.
Yes.
High yes, low sometimes. It does not like frequent cutting.
Yes, AFTER it establishes. Clip only the first year.
Reed canary usually beats tall fescue in the north. The big negative is that cows will not eat it if you try to stockpile. A nice long term low ground mix is MF, RC, WC, BFT. The RC establishes very slowly but it will take over as the others thin out.
I have grown RC with branch root alfalfa on high meadow. It makes better dry hay than the traditional clover mixes.
