The fall season provides a great opportunity to give your lawn some TLC after the stresses of summer.
Technically summer is over, but in most areas of the North East it still feels like summer outside. We all know that won’t last long and the cooler weather of fall will be here before we know it. That’s ok, though – your lawn will be looking forward to it, as this is a crucial time for bluegrass, perennial rye, fescue and hybrid tall fescue turf to follow the squirrel’s example and start bulking up and storing food for the long winter ahead.
In the fall, northern turfgrasses experience a peak in growth as temperatures start to cool down during the day and especially at night. This is the perfect time to give your lawn a good feeding and help tackle those ugly bare patches that may be covering your yard.
Fall fertilizer contains two key ingredients: nitrogen and potassium. Both will help stimulate and repair your grass. Look for fertilizer that has a high amount of available nitrogen in a slow release form, so that it feeds the lawn slowly and as the plant needs it. Be sure to read all packaging labels and apply fertilizer at the right rate to ensure you don’t overfeed and burn the lawn.
Potassium (potash) is equally important in the fall, so look for a fertilizer with a high percentage of it in the bag. Potassium plays a vital role in healthy turfgrass development and is second only to nitrogen in the amount required for lawn growth. Potassium enacts a protective mechanism in grass plants, hardening off cell walls to fight back against damaging factors. Turfgrasses that are deficient in potassium are more prone to injury during the winter months.
Keep in mind that fall is also a great time to seed the lawn, as ground temperatures are still warm and benefit from plenty of dew at night (this will help keep the seed moist). You should have an easier time getting the seed to germinate at this time of year, which will reinvigorate any bare spots that need repair. For larger areas, an aeration combined with an overseeding will really help that neglected lawn come in green and hardy next spring.
Keep those lawns healthy,
