Why do we recommend wrapping
trees at this time of year? It’s not unusual for winter temperatures to reach
60° Fahrenheit in the daytime and then fall below freezing after the sun goes
down. When it gets this warm, the low winter sun heats up the tree bark,
especially on the south and southwest sides of the tree. The sun’s warming
action breaks the trees dormancy and the cells on that side of the tree wakeup
and become active. When the temperatures
fall after sunset, the active cells and tissue die.
The damaged area will
sometimes shrink and discolor. Later in the season, the bark may fall off,
leaving a long scar.
Applying tree wrap now will help protect the tree from the
winter sun.
Tree wrap is a corrugated paper product, sold in 50' and 150'
rolls.
Apply tree wrap so the printed side is out. A good rule of thumb is to
wrap your trees around Halloween and remove the wrap around Easter.
You want to
leave the tree wrap off during the growth months of spring and summer. You should wrap trees for the first six or
seven years after you plant them. After that, the bark should be thick enough
to reduce the risk of sunscald damage.
