With very few exceptions, the answer is yes.
Autumn is an especially great time to plant shrubs and trees.
I'm hard at it, adding native trees and shrubs like those pictured here. Everybody knows a few native plants, but there are many beautiful, nearly pest-free shrubs and trees that are hard to find in the trade. My newest acquisitions include Cliftonia monophylla , known as titi or buckwheat tree. Bob's Big Four Bob Brzuszek, curator of Crosby Arboretum in Picayune, MS, encourages the use of native plants in home landscapes. He teaches folks to look at their property and assess the characteristics important for plant growth.
