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.
