I live borderline in Zone 8 and 9 in NC. My tea olives do not look healthy this year. We had some very cold weather for approx 2 weeks straight and I thought this might be the reason. They are 5 years old and have never looked dull and dry at this time of year. What could my problem be?

This could definitely be due to the excessive cold weather. After it warms up some, you can take off any dead growth and the plant will, then, make new growth.
