If you love avocados, but not their expensive price tag, listen up. Summer is a good time to stock up on seasonal produce like avocados, because not only are they in abundance, they are also at their lowest prices. And you won't have to go on an avocado-only diet to get full use of them, because you can freeze the extras. Just cut avocados in half and remove the pits. Keep the skins on and place the avocado halves in a freezer bag; squeeze the excess air out of the bag before sealing it shut. Avocados will keep in the freezer for about three months, so whenever you want to whip up some guacamole in the fall, your stash will be at the ready.

The majority of litter at beaches isn't caused by litterbugs -- it's from lightweight, single-use products packaged in wrappers and empty plastic bottles that fall out of trash cans or are blown away by gusts of wind. If you have trash from your day at the beach, don't use the trash receptacles there; take your trash with you. Bring it back home or to a hotel where refuse can be properly disposed of. There are even smartphone apps to help you locate the closest recycling bin, too.

Sadly, it's not uncommon to see a landscaping sprinkler system running at full power during a rainstorm. However, it's not the mark of a wasteful homeowner; it's because the sprinkler system is on an automatic timer. To fix this problem (and save water and money), have a rain sensor installed to your sprinkler system. The sensor determines whether enough rainfall has occurred to skip an irrigation cycle. If the sensor detects enough rain, it breaks the electrical connection to your sprinkler system so it won't turn on. It's easy to install and makes your sprinkler system more efficient.
