Is your house getting enough shade from the trees in your yard? The US Department of Agriculture notes that the net cooling effect of a shade tree is equivalent to 10 room-size air conditioners operating 20 hours a day. Just think of the energy savings a large tree can provide! Additionally, mature shade trees add value to your home. The Council of Tree and Landscape Appraisers states that “a mature tree can often have an appraised value of between $1,000 and $10,000.”
If you already have trees around your house, be sure to do all you can to keep them healthy. Water adequately. Even with our Stage 1 drought watering restrictions you can spot-water trees and plants as needed. And don’t forget to water in the winter! In the spring, a light feeding will help your trees shake off the winter and produce abundant leaves.
If you’re looking to add a tree or two, we have a few favorites to recommend:
Boxelder Maple, Sensation (Acer negundo sensation)
At 30 feet tall and 20 feet wide, this maple won’t overwhelm a small yard yet it still gives ample shade. The Sensation variety of this Colorado native tree features green leaves tinged with a hint of red on new growth, and a lovely coppery red in the fall. As a bonus, this hardy tree does not suffer from iron chlorosis. Needs moderate water. Zones 3 to 8.
Red Oak (Quercus rubra)
This oak features green leaves that turn red in the fall. At 50 feet tall and 30 feet wide, it will provide cool shade all summer long. It’s a long-lived tree and will tolerate our city pollution and marginal soils. Somewhat drought tolerant. Zones 3 to 8.
Autumn Purple Ash (Fraxinus americana)
This tree’s rounded form reaches 40 feet high and about as wide. The green leaf turns reddish purple in the fall, with yellow on the inside of the canopy. It holds its color in the fall longer than any other tree. Zones 4 to 9.
