Shade: On a scorching summer day, it’s one of the most valuable assets for any home in the Sacramento region – and you can grow your own.
“It’s the difference between a livable summer and one that’s really stifling, not just uncomfortable but could threaten your life,” says Stephanie Robinson, communications and marketing manager for the Sacramento Tree Foundation. “If you lost a big shade tree recently, you really noticed the difference – especially this summer. You don’t realize until it’s gone how valuable shade is.”
Not only your own home is affected, she adds. “Shade trees keep your whole neighborhood cooler. Without trees, all that heat is absorbed by asphalt.”
Tree-lined streets lower the temperature of surrounding homes and improve the neighborhood’s quality of life, Robinson notes. “That’s why it’s one of the main priorities for our mission (at the foundation); plant more shade.”
SacTree volunteers tested their theories of shade tree impact on neighborhoods with a drive around Sacramento neighborhoods on a summer afternoon, Robinson says. “There was a 20-degree difference between the hottest and the shadiest neighborhoods at afternoon peak highs. That can be the difference between life and death for people without air conditioning.”
Now is the time to plan ahead and plant some shade. Fall is the best tree-planting season in the greater Sacramento area. While some trees have reputations as water hogs (specifically coastal redwoods), many other water-wise choices are available.
“If you’re re-doing your landscape, think trees first,” says Robinson. “It’s not just shade, but wildlife habitat. You can build trees into your water budget. It costs less than $3 a month to water a mature tree. A young tree costs only pennies. You can afford to invest in that shade.”
SacTree partners with the Sacramento Municipal Utility District (SMUD) to offer up to 10 free shade trees to customers. Since 1990, the program has planted more than 600,000 local trees. Details here: https://www.smud.org/en/Going-Green/Free-Shade-Trees
Participants contact SacTree and set up an appointment with a community forester. That program has expanded to include evergreens as well as trees that shade portions of a customer’s property other than their home.
“Shading landscape saves water because there’s less transpiration,” Robinson says. “There are many benefits of shade trees.”
Among the most popular water-wise shade trees for Sacramento landscapes are native oaks: Valley oak, interior live oak and blue oak.
“People love oaks,” says Robinson. “They’re sturdy, long-lived and (the deciduous varieties) offer a rainbow of fall color.”
Oaks take time to grow. A faster option is a zelkova; native to Japan, these trees can reach 60 feet in a hurry. “It’s a big, beautiful shade tree that grows fast,” Robinson says.
“Chinese pistache are still very popular, and the new cultivars are not as messy,” she adds. “Right now, people are very interested in trees that flower and support pollinators. The favorites are desert willow, vitex and strawberry trees.”
SacTree has many more suggestions in its “Shady 80,” its selection of best trees for Sacramento. This urban forest features dozens of water-wise choices: https://sactree.org/best-trees-for-sacramento/.

Dig In: Garden Checklist
For week of Feb. 18:
It's wet to start the week. When you do get outside, between or after storms, concentrate on damage control:
* Keep storm drains and gutters clear of debris.
* Clean up tree debris knocked down by wind and rain.
* Where did the water flow in your garden? Make notes where revisions are necessary.
* Are any trees leaning? See disturbances in the ground or lawn around their base? Time to call an arborist before the tree topples.
* Dump excess water out of pots.
* Indoors, start peppers, tomatoes and eggplant from seed.
* Lettuce and other greens also can be started indoors from seed.
* Got bare-root plants? Put their roots in a bucket of water until outdoor soil dries out. Or pot them up in 1- or 5-gallon containers. In April, transplant the plant, rootball and all, into the garden.
* Browse garden websites and catalogs. It’s not too late to order for spring and summer.
* Show your indoor plants some love. Dust leaves and mist to refresh.
