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.
