Trees of Colorado: The Autumn Blaze Maple
Are you envious of the beautiful fall colors of New England? Or do you just want a shade tree that will turn heads with a blaze of color when summer turns to fall? Then the Autumn Blaze Maple is the tree for you.
Sheath Your Shears till After the Snow Flies
Fall is a hard season to predict along Colorado’s Front Range. The earliest freeze in Denver was on September 8, 1962, but just 18 years earlier it didn’t come till November 15. In 1961 it snowed on Labor Day! The National Weather Service pegs October 7 as the average first freeze date, but if you’ve lived in Colorado for any length of time, you know there’s nothing “average” about the weather here. Even the experts can only nail down the first frost to 60-day window.
September is National Preparedness Month
Winter brings on a host of challenges for homeowners. They range from winterizing your house for comfort and energy savings to maintaining your trees to avoid winter damage and having a plan in case trouble strikes.
The Federal Emergency Management Administration (FEMA) designates each September as National Preparedness Month to remind us that we need to plan for the unexpected and be ready to meet the challenges it brings.
