Gardening Tips for May
- Set out traps for earwigs, slugs, and whitefly.
- Thin pit fruits at or before pit hardening.
- Thin apples when ½” diameter.
- Mow grass or cultivate soil around orchard to discourage thrips and plant bugs.
- Mulch around plants to control weeds and conserve moisture. Be sure to leave a small circle of bare soil around the base of each plant.
- Deep water trees and shrubs. Build water basins, but do not allow water to stand against the trunks.
- Prepare dahlia bed with rich soil.
- For continued bloom, cut off spent flowers.
- Hang strips of foil or CD’s in fruit trees to help deter birds.
- As spring=flowering shrubs finish blooming, prune to shape, removing old and dead wood.
- Trim hedges; lightly trim azaleas, fuchsias, bushier plants.
- Thoroughly clean debris from ponds, fountains and bird baths.
- Check dates of Master Gardener classes.

Monarch Sightings in the UC Davis Arboretum: Cause for Celebration
Posted 5/26/2017 - What a delight to see. We strolled through milkweed patches in the UC Davis Arboretum Thursday noon and saw them. Monarchs! The monarch butterflies (Danaus plexippus) are returning from their coastal California overwintering sites. And we're getting new generations. The UC Davis campus, including the 100-acre UC Davis Arboretum is home to much celebrated flora and fauna, including milkweed and monarchs. After overwintering along the California coast and in central Mexico, the butterflies...
Christine Merlin and Monarchs: How They Use Their Circadian Clocks for Seasonal Migration
Posted 5/25/2017 - Did you know that monarch butterflies use a circadian clock to navigate to their overwintering sites during their seasonal long-distance migration? Yes, they do, says a Texas A&M researcher. Christine Merlin, an assistant professor in Texas A&M's Department of Biology, will discuss her research on "The Monarch Butterfly Circadian Clock: from Clockwork Mechanisms to Control of Seasonal Migration" when she presents a seminar on Wednesday afternoon, May 31 at the University of...
Bumble Bees: Pollen Power in the Phacelia
Posted 5/24/2017 - Talk about pollen! The bumble bees, Bombus vandykei (as identified by Robbin Thorp, distinguished emeritus professor of entomology at the University of California, Davis), were buzzing all over the Phacelia last week on the central campus. One bumble bee carried a heavy load of orange pollen (collected nearby), while another, a small load of blue pollen. They both wanted the same flower. I'll have what you're having! Move, please. Sorry. I'm not finished here. She didn't move. Not...
Meet Big Red, the Flameskimmer
Posted 5/23/2017 - Big Red visited us for four consecutive days. The red flameskimmer dragonfly, Libellula saturata, zigged and zagged into our pollinator garden in Vacaville, Calif. and perched on a bamboo stake for five hours at a time. Occasionally, he'd hunt--lift off and grab a bee or other insect--and return to the stake to eat it. Meanwhile California scrub jays nesting in our cherry laurel hedge eyed him. Hmm, there's lunch! And there's lunch having lunch! Big Red knew they were there but paid...
She'll Speak on The World's Most Dangerous Animal
Posted 5/22/2017 - The world's most dangerous animal isn't the shark, wolf, lion, elephant, hippo, crocodile, tsetse fly, tapeworm, assassin bug (kissing bug), freshwater snail, dog, snake or human. No, it's the mosquito. Infected mosquitoes transmit diseases that account for some 750,000 deaths a year, according to a recent article in Science Alert. The mosquito is a piece of work. Remember when several UC Davis scientists were featured in a KQED-produced science video on "How Mosquitoes Use Six Needles...
