These are our native maples, the Bigtooth and the Rocky Mountain, in among Gambel Oak.  Aren't they awesome?  I love this time of year!

 

Tree Tip: Continue to water your trees through the fall and into winter if we have long dry spells--deep and infrequent is the key! You want the water to soak the roots, but only need to do this every 2 to 3 weeks (or longer) depending on the weather.  Evergreens and conifers will need supplemental water all winter, if we go too long without snow cover or moisture.  Their systems don't ever go dormant completely, and need water to prevent winter burn.

Happy Gardening!
