Winter Chill

14 Jan Winter Chill

A blanket of snow covered our orchards last night. It may seem cold to us, but apple and cherry trees need this “winter chill” to store energy for the blooming and growing seasons. Weather such as what we are experiencing now and temperatures at or under 45 degrees Fahrenheit allow our trees to rest and enter a dormant period.

In fact, each fruit tree has a certain amount of chill units/hours that should be met for optimal and high quality fruit. For apples trees, 800-1,100 hours or chill units are needed (for cherries, 1,000+).

So… zip up your coats, put on some gloves, and enjoy this weather! The heat of the summer can wait for now.
