November...

General
Keep leaves out of roadways or drains. (They can wash away and pollute waterways with phosphorus.) Shred fallen leaves with a mulching mower or collect leaves and compost them before snowfall mats down leaves, which can kill turf.

Fertilizing
If you fertilize only once a year, a single application (1 lb. N/1,000 square feet) between Halloween and Thanksgiving (about 2 weeks after your last mowing) is the best time. Most home lawns with modest expectations do just fine with a single late-fall fertilization.

Mowing
As long as the grass is growing, continue to follow the “One-Third Rule,” never removing more than one-third of the plant. (If you set your mower to mow at 3 inches, mow before the grass reaches 4.5 inches tall.)
