Save money on your water bill without leaving your precious plants to wilt with thirst simply by spreading a layer of mulch over your garden beds. The layer of insulation it creates will inhibit ground water from evaporating in the sunlight. As a result, each rainfall or sprinkler session lasts longer, helping limit the number of times in a month you need to be watering—not to mention the cost of your water bill. To reap the benefits of mulch in your own flower beds this season, spread a thick layer of wet newspaper over your soil and top it with at least an inch of mulch. The paper will decompose, leaving you with richer soil. Available at Amazon; $15.
