Don’t let the snow start falling without first taking care of your lawn, the Old Farmer’s Almanac says. To ensure a lush, green expanse of grass in the spring, rake and dethatch your lawn, then aerate it to reduce soil compaction. October is a good time to fertilize, weed and seed your lawn, too, to promote new growth that crowds out broadleaf weeds. Buy a soil test kit from your local garden center to if you’re having trouble establishing grass and other plants; you’ll want to balance soil to about 6.5 pH and may need to add lime, sulfur, potash, potassium and other enhancements to get your grass to grow.
