A: Pam Knox, director of the UGA Weather Network, looked at the number of days on which the 2-inch soil temperature at the Rome weather station (closest to Bartow County) was at or below freezing. She found only two days in the last 10 years on which the soil was frozen. Farther north, in Blairsville or Ringgold, the soil might be colder, but my bet is that even then there are many days of winter when the soil in North Georgia is not frozen. It is fine to plant the arborvitae now. But it is critical to keep the root system moist for at least six months lest the roots dry out.
Q: Online guides say that you can cut main limbs of a lilac to the ground to encourage new growth. My single-trunk lilac is 10 feet tall but I want it to be lower and bushy. Beryle Tylar, email
