By now, major lawn renovations should probably wait until early spring because there is not enough time to get good growth before dormancy, however, there’s still time early in the month to do things like aerate and patch seeding. PERENNIAL RYE BLEND is your best option if you have to plant a lawn this time of the year. It’ll come in fast (7-10 days) and holds up well over winter. Overseeding may be necessary in the spring.
Overseed under deciduous trees. With leaf drop and dormancy, there is more light and less competition for nutrients and water.
Fall is the best time for liming your turf. Lime added to the surface of a lawn takes a long time to work its way down and raise the pH. Thus, a fall application will produce results by the spring growing season. The only way to know whether you need lime and how much to put down is to have a Penn State Soil Test done. Everything else is just guess work and may not be of use.
This month is getting late to overseed and/or fertilize as the shorter days slow the growing process. It is, however, a great time to attack those hard to kill weeds (such as ground ivy) with a weed killer like Bonide Weed Beater Ultra or Ortho Weed B Gon.
