1. Give your lawn one last cut.
Even if the weather is cold continue to mow your lawn until it stops growing. When the snow falls if the grass is to tall it will pack down and cause snow mold. You need for the sun to get thru the blades of grass to the surface area.
2. Test your soil.
November is a good time to apply grass seed, it is crucial to test the soil to determine pH and nutrient availabilities. Deficiencies need to be corrected or you're just wasting time and money. Send a soil sample for professional testing that will run you about $15 — it's well worth it on your pocket book.
3. Then reseed the lawn.
Once the soil is tested and deficiencies are corrected, if needed, it's time to aerate and seed the lawn that is stressed from the summer's sun or trampled from foot traffic. Pending the condition of your lawn, you typically need about three pounds of seed for every 1,000 square feet. Use a certified seed (or contractors seed), meaning its mostly pure grass seed with very little weed seeds or fillers.
4. Remember to fluff up the mulch.
Officially called turning the mulch. Fluffing it up gives flowerbeds a fresh look and cuts down on, or may eliminate, the need for more, fresh mulch. Should you end up adding new mulch, keep it around two to three inches thick. More than that, and the mulch becomes a hiding place for insects and plant diseases, and water could have a harder time being absorbed.
5. You could make your own mulch.
After you turn the mulch, and you decide you need more, try making your own. Simply run your lawnmower over, your abundance of leaves (we all have this time of season), a few times and use them as mulch for your flower beds. Leaves are an excellent source of organic matter that your plants will love you for.
6. You may want to do some planning and planting, as well.
Fall is a great time to plant, see what plants need to be separate / divided / thinned out, especially perennials like Hosta, Daisies, Lilies and Iris plants and look where your landscape area needs to be filled in for next year to look even better. If you have summer annuals, swap them out for Fall-appropriate plants like Mums and Pansies.
7. Give your driveway and walkways some TLC.
Driveways and Walkways are all part of your landscaping overlook, they are a big part of your “Curb Appeal”. Fall is an important time to fill cracks in asphalt or concrete, and apply a concrete/asphalt sealant to help prevent water penetration damage from freezing and thawing. Should water get into cracks and freezes, you are at high risk of more damage.
8. Water your Evergreens.
In September and October all evergreens should be sufficiently watered to reduce the possibility of winter dehydration. How much water do you need? That depends on the recent weather. If it's a rainy fall, no water is necessary. If it's less than four inches of rain for the month, you'll need one or two thorough hour-long watering’s a week for up to three weeks.
9. Do some pruning.
Typically a heavy pruning is needed for all Trees and Shrubs, before the cold winter. Some may need it to help prevent damage from snow and ice storms and some just for looks or to control the size for next spring. Don't prune certain flowering plants like hydrangeas, lilacs, and viburnum, it could spoil the spring blooms.
10. Pack up / away for the winter.
Bring in all of your tools, sprinklers and, especially hoses, when your chores are done. Water in the hose will expand when it freezes and damage the hose. And don't forget to have all irrigation lines blown out to prevent lines, heads and valves from cracking.
