Q: Can I transplant my hydrangeas to Zone 9, Florida? They are about three feet tall and wide.
A: Hydrangeas will grow in zone 9 if you give them light shade all day long and if they are watered properly in summer. Unless yours are very special to you, I think I would rely on a local nursery there to recommend varieties that grow best in your new location. Look around your new neighborhood in spring and notice how good-looking hydrangeas are situated in the local landscapes.
