I live off Hwy. 281 about 3 miles from downtown Blanco toward Johnson City. The plants that froze at my place were four-o-clocks. Downtown at City Hall, the four-o-clocks and lantana were nipped and they had to be trimmed. It just goes to show that different areas in the same town can have different climates. We all have our own micro-climates. Just be prepared for changes in the weather and treat accordingly.
This is the time to plant trees and shrubs. Look for container or boxed grown trees. These are trees grown from seed or cuttings grown in the container and moved into larger pots each year. The trees will be better to plant than B&B (balled and burlapped). A large amount of roots are left in the planting hole when the trees are dug. Be sure that you place several inches of mulch around the planting hole. Water regularly. Do the research on the type of trees you wish to plant. Do you want color, evergreen deciduous, large shade trees, or small decorative trees such as crape myrtles? First, it needs to be for our part of Texas. If you want oak trees, there are several that hold their leaves during the winter. Red oaks are the only oak tree that turns brilliant colors in the fall. Live oaks turn yellow. The Shumard Red Oak doesn't do well in the Blanco area. Remember, the red oaks often are the culprits for OAK WILT. Look for Lacys oak, Burr Oak, or Mexican Oak, known as Monterrey Oak.
The same goes for peach trees. Peach trees that grow in Fredericksburg and Stonewall don't necessarily mean they will do well in Blanco. It depends on the chilling hours. Check with the local growers and nurseries. The County agent in Johnson City will be able to help you.
