Oak grove to honor Tretheways

SacTree's longtime leader retires with virtual ribbon-cutting

What kind of tree would Ray Tretheway be?

No question; a Valley oak, of course, he said with a laugh. “It’s the longest living native oak, the largest that we have. It goes with our climate. It’s native to Sacramento.”

Just like Ray Tretheway.

For nearly four decades, Tretheway has been as strong and steady as a Valley oak. In the City of Trees, he’s been Sacramento’s outspoken and buoyant advocate for our urban forest.

Now, it’s his turn to enjoy a break in the shade.

Next week, Tretheway is retiring as executive director of the
Sacramento Tree Foundation .

“We’ve built a great platform, a springboard that’s very strong,” Tretheway said. “It’s time for younger people to take the helm.”

Tretheway has led SacTree since it sprouted on California Arbor Day in 1982. When he was officially named executive director in 1990, he became the foundation’s first full-time employee.

“When we started, our goal was to plant a tree a day,” recalled the 73-year-old Tretheway. “We planted 400 our first year.”
Now, SacTree’s total is somewhere over a million. Every year, the foundation helps plant many thousands, mostly through its shade program partnership with SMUD; it accounts for more than 600,000 trees and counting.

“It’s been magical,” Tretheway said. “I worked a lot of long hours, not selling a product across the counter but selling a vision. It’s now time to enjoy the world.”

SacTree is celebrating Tretheway’s legacy the best way it could – naming an oak-filled park in honor of Ray and his wife, Judy. To be shared via Facebook, a ribbon-cutting ceremony and dedication will be held at 11 a.m. Nov. 19 at the Ray and Judy Tretheway Oak Preserve, formerly the Natomas Oaks Park.

“Due to (COVID) safety precautions, it won't be a public event, but we will livestream it on Facebook for all to view and share their well wishes or memories with Ray,” explained SacTree spokesperson Stephanie Robinson.

Nearly 13 acres of oaks on River Plaza Drive near Garden Highway will be a living tribute to Tretheway’s lifetime of service. Besides leading the foundation, he also served as a Sacramento city councilman for 10 years.

“We are also launching a special campaign to honor Ray, and gifts will go toward two initiatives very close to his heart,” Robinson said. “The first $50,000 raised will go to preserve the native oaks and flora of this park and add some amenities to support outdoor education. All other contributions will go toward the Evergreen Fund, projects that improve canopy equity throughout the region.”

A Sacramento native, Tretheway grew up with an admiration for nature. After working in Washington D.C. as an environmental researcher and at the Smithsonian Institution, he returned to his hometown to advocate for the environment.

“For years, ‘urban forest’ was an oxymoron,” he observed, noting cities didn’t actively campaign for trees.

“Now, we understand that 85, 90% of our urban forest is owned and controlled by home and property owners where they live,” he added. “Our urban forest is living, natural and affects every person’s life. It’s linked to our quality of life and health.”

Tretheway will continue to work with trees and people. His focus recently has been planting trees in historically impoverished (and treeless) neighborhoods.

“It’s been a dynamic career; not a job, but a pleasure,” he said. “How else do you get to live a vision?”

Dig In: Garden Checklist

For week of March 19:

Spring will start a bit soggy, but there’s still plenty to do between showers:

* Fertilize roses, annual flowers and berries as spring growth begins to appear.

* Watch out for aphids. Wash off plants with strong blast from the hose.

* Pull weeds now! Don’t let them get started. Take a hoe and whack them as soon as they sprout.

* Prepare summer vegetable beds. Spade in compost and other amendments.

* Prune and fertilize spring-flowering shrubs after bloom.

* Feed camellias at the end of their bloom cycle. Pick up browned and fallen flowers to fight blossom blight.

* Feed citrus trees as they start to blossom.

* Cut back and fertilize perennial herbs to encourage new growth.

* Seed and renovate the lawn (if you still have one). Feed cool-season grasses such as bent, blue, rye and fescue with a slow-release fertilizer. Check the irrigation system and perform maintenance. Make sure sprinkler heads are turned toward the lawn, not the sidewalk.

* In the vegetable garden, transplant lettuce and kale.

* Seed chard and beets directly into the ground.

* Plant summer bulbs, including gladiolus, tuberous begonias and callas. Also plant dahlia tubers.

* Shop for perennials. Many varieties are available in local nurseries and at plant events. They can be transplanted now while the weather remains relatively cool.
