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.

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...

Have You Seen Me? Can You Identify Me?
Posted 5/19/2017 - Have you seen me? Can you identify me? No, you're a skipper, but which one are you? The colorful brown skipper butterfly that touched down on our Jupiter's Beard in Vacaville, Calif., on May 17 puzzled us.  First skipper we've seen this year in our pollinator garden, but what was it? Butterfly guru Art Shapiro, UC Davis distinguished professor of evolution and ecology, who has studied butterflies for more than four decades--and who posts his research and observations on his Art's...

Bears Raiding Bee Colonies: They're Seeking the Brood
Posted 5/18/2017 - Yes, bears raid honey bee colonies. But it's primarily for the bee brood, not the honey. The brood provides the protein, and the honey, the  carbohydrates. For beekeepers and commercial queen bee breeders, this can wreak havoc. Financial havoc. The American Beekeeping Federation, headed by Gene Brandi of Los Gatos, recently asked Extension apiculturist emeritus Eric Mussen of the UC Davis Department of Entomology and Nematology to respond to a question about bees and bears. Mussen, who...

A Face Only a Mother Could Love?
Posted 5/17/2017 - So there we were, on Mother's Day, looking at the yet-to-bloom English lavender in our yard. And there it was, something golden staring back at us. It was showing a face that "only a mother could love"--or an entomologist or an insect enthusiast. Scathophaga stercoraria, the golden dung fly. A red-eyed blond fly. It's a beneficial insect. The larvae are often found in the feces of large animals, including horses, cattle, sheep, deer and wild boar, where the insect breeds. (Note: We have no...

A Honey of a Festival, and an Inaugural Festival at That!
Posted 5/16/2017 - It was indeed a honey of a festival. When the inaugural California Honey Festival buzzed into Woodland on Saturday, May 6, organizers figured attendance might total around 3,000. No. It did not. It tallied about 20,000, according to organizer Amina Harris, director of the UC Davis Honey and Pollination Center. And this was the inaugural one! Next year is the second annual... The festival was all about honey, bees, and beekeepers. Just as the queen bee reigns in a colony, bee products...
