Have you noticed? We’re having a spectacular tree season!
This month, maples, pistaches, ginkgos and other deciduous trees are putting on a colorful show with rich reds, golds and oranges.
Before those leaves are gone, check out the gorgeous trees at the UC Davis Arboretum with the help of a new self-guided tour of campus trees.
“This tour moves you through a 1.5-mile loop on the UC Davis campus while teaching you about both common and unique tree species,” says the arboretum staff. “It’s perfect for navigating in-person from your smartphone!”
You also can check it out on your laptop computer or tablet. Find the links here: https://storymaps.arcgis.com/stories/ed81abebde784d2f824268402fb3ed1b
The tour and virtual resources were created by students participating in the arboretum’s Learning by Leading Tree Stewardship program. Among the thousands of trees on campus, 21 specimens are highlighted on the self-guided tour.
For visitors to the arboretum, parking on campus is free on holidays and weekends.
Besides the tour, the students also came up with several other tree-friendly resources including webpages on the benefits of trees in a suburban environment, the effects of climate change on our trees and forests, and details on a Campus and Community Action Plan with ways students and residents can support their tree canopy.

Garden Checklist for week of May 5
Survey your garden after the May 4 rainstorm. Heavy rain and gusty winds can break the neck of large flowers such as roses. Also:
* Keep an eye on new transplants or seedlings; they could take a pounding from the rain.
* Watch out for powdery mildew. Warmth following moist conditions can cause this fungal disease to “bloom,” too. If you see a leaf that looks like it’s dusted with powdered sugar, snip it off.
* After the storm, start setting out tomato transplants, but wait on the peppers and eggplants (they want warmer nights). Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.
* Trim dead flowers but not leaves from spring-flowering bulbs such as daffodils and tulips. Those leaves gather energy to create next year's flowers. Also, give the bulbs a fertilizer boost after bloom.
* Pinch chrysanthemums back to 12 inches for fall flowers. Cut old stems to the ground.
* Mulch around plants to conserve moisture and control weeds.
* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, pumpkins, radishes and squash.
* Plant onion sets.
* In the flower garden, plant seeds for asters, cosmos, celosia, marigolds, salvia, sunflowers and zinnias. Transplant petunias, zinnias, geraniums and other summer bloomers.
* Plant perennials and dahlia tubers for summer bloom.
* Don’t wait; plant summer bulbs, such as gladiolus and tuberous begonias.
* Harvest cabbage, lettuce, peas and green onions.
