Answer: Your gardening zone is marginal for citrus trees outdoors. You can try, but you'll need to protect them from sudden freezes. Or, you can keep them in containers and winter them over indoors, taking them outside for the spring and summer months. Keeping them indoors isn't too difficult; provide lots of bright light, warm temperatures, moist soil, and keep them out of drafts. They may even flower and begin to produce fruit indoors if the environment pleases them.
Enjoy your new trees!
