Mow the lawn twice a week
Grass grows faster in the summer so mow your lawn regularly. Every other lawn cutting, try mowing on the diagonal to add dimension and curb appeal.
Create summer curb appeal
Curb appeal attracts people in the market to buy homes. Trim the bushes. Plant flowers. Scatter mulch. Paint your house number on the curb. Sweep the walk. Make your entrance
welcoming and warm.
Decorate with summer accents
Look around your home for color inspiration. Add vivid blue decor items for a calming effect. Replace dark-colored accent pillows and throw rugs with brighter, summer hues.
Bring the light inside
If you have heavy drapes, remove them. They make rooms look smaller. Pull window blinds to the top and tape the strings underneath. Consider using tie-backs to hold open lighter-weight curtains. The only time you would leave blinds closed is if there was an undesirable element on the other side of the window, i.e. a neighbor's trash can, and even then, open them slightly.
Gold or silver or brass or pewter? Doesn't matter. Mix them, if you like. Old rules don't apply. Metals are summery. Vases, picture frames, mirrors, utensils, goblets, hanging planters and garden gnomes all work.
Offer summer beverages and snacks
For me, in California, summer means red-and-white checkered tablecloths, potato salad, hot dogs and mustard and roasted corn-on-the-cob. Every part of the country has its own summer food traditions. Fill the sink with ice cubes and chill bottled beverages for visitors and offer a few light snacks.
Use natural air freshener
Fill the air in your home with natural fragrances such as those from fresh cut roses, grown in your own garden as commercial has no scent.
Control air temperature
There's nothing worse than a stuffy room on a hot day. Circulate the air in your home. Even if you have to place floor fans about the home, keep the air moving. Turn down the air conditioning to a level just below your comfort zone on extra hot days. A cool indoors will keep visitors indoors viewing your home for longer.
