Q: Can I grow a bald cypress tree--the ones you see in Southern swamps--in my Arkansas backyard? A: Of course you can. You don't have to convert your backyard to a swamp to do it. The bald cypress is a deciduous conifer that's hardy in Zones 5 to 11. It prefers full sun and a fairly steady supply of moisture, so mulch it well and water it regularly. Give it plenty of room too, because it can grow to 60 feet tall and half as wide.
