September Lawn

    By Nancy Bolton

    September is the perfect time to seed/reseed a lawn.  Fortunately, this is not done yearly.  It is also time to fertilize cool season grasses.

    • Soil test if not done within the last 3 years
    • Aerate lawn if compacted
    • Mow as needed at height of 3-3 1/2″. OK to be slightly shorter so sun can get down to base of grass blades.
    • Great time to lay sod
    • Great time to reseed. Start by adding some compost. Pick certified seed and water frequently until germinated and then at least 1/2 inch every 2 or 3 days. Do not fertilize 2 weeks prior to seeding and 4 weeks after seeding even if means omitting one of the three applications. Do not mow until grass is 3 to 4 inches
    • Fertilize lawn as indicated by the soil test.  See feature article for more information.
    • Measure lawn dimensions prior to fertilization.
    • Use slow release fertilizer when possible
    • Do not let fertilizer spread in a manner that falls on impervious surfaces such as sidewalks and driveways
    • Avoid fertilizer application if weather report calls for heavy rain
    • Return grass clippings to lawn
    • As leaves fall, chop them finely with a mulching mower.
    • Lime as indicated by soil test but no greater than 50 pounds/1000sq ft at one time.
