The weeks we are having right now are the best time of the year to plant shrubs and perennials for our summer dry climate. The soil is still warm from summer and autumn, but now it’s also thoroughly moist from the first weeks of good rain. The sunny days with fluffy, white clouds that come between rainstorms are the ideal time for planting. Newly installed plants will have five or six months to get their roots down into new soil before they get their first drought stress test, often in late May or early June when the first dry hot day of the new year comes along.

As I brushed against the beautiful blue flowering Salvia guaranitica I saw a burst of movement out of the corner of my eye. I would have loved to ignore it and just keep on pruning, but I’m an old and wily gardener, and I know it’s best to investigate anything unusual I see in my garden immediately. Sure enough, when I brushed the Salvia again, there was a burst of action. Tiny white insects swarmed for a moment and then settled back onto the undersides of the leaves. Oh no. Whitefly.

One of the great pleasures of climate-wise gardening in the Bay Area is the beautiful winter bouquets we can cut from our flowering trees and shrubs. When the rainy season starts, climate-wise plants wake up from their dormancy during the dry summer and fall. Many of them start blooming immediately. Salvias, tea trees, tree aloes, and grevillias are just some of the plants blooming now at Garden for the Environment.
