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?”

Garden Checklist for week of July 7

Take care of garden chores early in the morning, concentrating on watering. We’re still in survival mode until this heat wave breaks.

* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to conserve moisture.

* Prevent sunburn; provide temporary shade for tomatoes, peppers, eggplant, melons, squash and other crops with “sensitive” skin.

* Hold off on feeding plants until temperatures cool back down to “normal” range. That means daytime highs in the low to mid 90s.

* Don’t let tomatoes wilt or dry out completely. Give tomatoes a deep watering two to three times a week. Harvest vegetables promptly to encourage plants to produce more.

* Squash especially tends to grow rapidly in hot weather. Keep an eye on zucchini.

* Some weeds thrive in hot weather. Whack them before they go to seed.

* Pinch back chrysanthemums for bushy plants and more flowers in September.

* Harvest tomatoes, squash, peppers and eggplant. Prompt picking will help keep plants producing.

* Remove spent flowers from roses, daylilies and other bloomers as they finish flowering.

* Pinch off blooms from basil so the plant will grow more leaves.

* Cut back lavender after flowering to promote a second bloom.

* One good thing about hot days: Most lawns stop growing when temperatures top 95 degrees. Keep mower blades set on high.

* Once the weather cools down a little, it’s not too late to add a splash of color. Plant petunias, snapdragons, zinnias and marigolds.

* After the heat wave, plant corn, pumpkins, radishes, winter squash and sunflowers. Make sure the seeds stay hydrated.
