Answer: Either spring or fall are good times to plant. That's when temperatures are generally cool and rainfall abundant, both of which will help your new trees develop strong root systems before they are triggered to produce top growth. If you've found the trees you want to plant, go ahead and plant them now. If you can't find the appropriate trees, you'll have all summer to find them and you can safely plant them in the early fall.
Best wishes with your new trees!
