When rainfall and temperatures begin to moderate at the end of summer, it's time to start thinking about fall planting. Fall is a good time to plant many differentkinds of trees and shrubs and even perennials. Fall-planted specimens often settle into their new homes more easily than those planted in spring, because they usually don't have to contend with a period of hot, dry weather the way the latter do.Timing of fall planting has much to do with soil temperature. Many plants can grow roots when the earth is as cool as 45°F. At planting time, the soil temperature at 6 inches deep should be about 55°F to give plants ample time to start getting established. Conifers prefer a soil temperature closer to 65°F, so they should be planted in earliest fall.
