what to do to maintain healthy grass in autumn
If you raised the height of your lawn mower in summer to reduce heat stress to your lawn, return the mower deck to its normal mowing height (about 2 inches tall is best for most grasses) in fall. Cutting your lawn slightly shorter in autumn helps prevent the grass from matting down under leaves and snow.verseed warm-season lawns with ryegrass each autumn. This type of grass provides a lush, green carpet through the cool winter months. Prepare the lawn for overseeding by mowing it 1/2 inch shorter than usual and removing the clippings. Sow grass seed over the mowed area, making two passes at right angles to each other.
