Napa Master Gardener Column

Years ago, on the last day of school, the assistant principal sent out an email to all the teachers. He suggested we sit down for a few minutes and review our academic year and think about what went well in our classes and what, perhaps, needed some rethinking.

Last fall I noticed a brown squirrel lounging on top of my owl nest box. She was just opposite my kitchen window so I put my binoculars there so I could watch her. Often she would be stretched out with her front paws hanging over the edge.

On any given day, air and surface temperatures tend to be higher in urban areas than in surrounding rural settings. This phenomenon is called the heat-island effect.

About 25 years ago, my children and I planted a particularly exuberant flower garden in the backyard. We had pink and purple, and white cosmos, brilliant blue morning glories and many colors of zinnias.

One of my neighbors, David Graves, is a partner in the Carneros winery Saintsbury. It's a small but thriving enterprise and very attractive because of its garden, making it a pleasant place to sit and enjoy the flowers and the bees, butterflies and hummingbirds attracted to them.
