4. Compost Yard Waste.
Dump collected leaves, cuttings, spent foliage, and last season's mulch into your compost pile, or make a simple corral by joining sections of wire fence (available at home centers) into a 3-by-3-by-3-foot cube like the one above. Shred leaves and chip branches larger than ½ inch in diameter to accelerate decomposition, or add a bagged compost starter to the pile. Keep the pile as moist as a wrung-out sponge, and aerate it with a pitchfork every two weeks. Just don't add any early spring weeds that have gone to seed—they might not cook completely and could sprout instead.
