Killing Freeze

What is a killing freeze (hard freeze)?

A killing freeze is when temperatures fall to or below 28ºF for at least a week. Most trees can survive brief periods of 32ºF. The killing freeze weather condition can kill a young fig tree if not protected. You can’t always make the best judgement when a freak cold blast comes down from Canada.

When autumn emerges, a tree will gradually drop it’s sap down to the base of the tree to help protect the branches from the Winter season, while it remains dormant. The problem that usually occurs is an early Spring during the month of March. At this moment, the weather warms up and the tree begins to leaf out as the sap returns to the branches.
