Answer: Sadly, it is true that spruces do not do well in areas with hot humid summers like the ones you experience. In addition to checking the winter cold hardiness zone, you also need to be aware of the summer heat tolerance of plants. The spruces for instance do better in New England or the Pacific Northwest where summers are cool. You might be able to grow a small juniper such as J. procumbens Nana instead if you need a blue toned needled evergreen, or if you prefer a more formal shape you might be able to use a small cultivar of boxwood and clip it to be a rounded ball or even to a conical shape depending on the variety you plant. Your local professional nurserymen should be able to show you plants that do well in your local area. I hope this helps in your selection process.
