Did you know that most houseplants thrive in an environment that's at least 40% humidity? That level is higher than what's found in the average home, but you can give your plants the environment they need without having to run humidifiers. The simplest way is to spray water from a misting bottle to saturate their leaves. You can also group plants together, which can create a small microclimate that increases the moisture levels in the space around them. Finally, fill a tray with pebbles and water and rest the potted plant on top; the water will offer a bit of humidity as it evaporates.

Your washing machine can develop a serious case of mildew. And according to Better Homes and Gardens, the simplest way to prevent mildew buildup -- which can make your newly washed clothes smell musty -- is to do one thing: Leave the door open. Whether it's front-loading or a top-loader, leaving the door or lid open after use lets the machine dry out. And since most of us are using cold water to wash our clothes, it's even more important to do this, since only hot water can kill mildew.

When it's time to replace an old refrigerator or freezer, it's important to make sure it's properly recycled. Most home improvement stores and dealers are capable of taking your old appliance and recycling when you buy a new one from them. If you need to dispose of one yourself, it's key to do it right, especially if the appliance was made before 1995 -- freezers and fridges manufactured prior to 1995 contained a type of insulation called CFC-11, which is an ozone-depleting substance. To find a disposal site, visit the EPA's Responsible Appliance Disposal site at epa.gov.
