An old trick of organic gardeners is to use fresh grass clippings as mulch in flowerbeds or vegetable gardens. Grass is a great natural mulch: It helps keep moisture in and blocks weeds out, and when it biodegrades, it's beneficial matter for the soil. But make sure it's organic. Since some lawns are treated with chemical fertilizers or herbicides (that target weeds but not grass), adding these to your garden could create a chemical cocktail that could kill your veggies and flowers.

We're used to looking at the expiration date on foods to know how late we can consume something, but according to Joanne Lacina, the founder of OliveOilLovers.com, we should be looking at the harvest date when it comes to buying olive oil. When an olive oil has a "best by" date, it could be anywhere between a few months or two years from the date of actual bottling. A harvest date, which also appears on olive oil bottles, tells you the exact date when the oil was pressed. This can give you a very clear indication of the age of your olive oil purchase.

As the warmer months are just around the corner, another thing that comes with spring days are ants invading our homes. The leading sources of ant infestations are dirty dishes that can pile up in the sink. But your dishwasher has an airtight seal that keeps ants out. By placing used utensils, dishes, bowls and cookware inside, you can keep the ants away, since the smell of old food will be trapped inside the dishwasher and not wafting in the air.
