Fruit Crops on the Line

With a freeze forecast for much of southern Minnesota tonight and tomorrow night, tree fruit crops all over the state are in danger. Many plum, apple and cherry trees are blossoming now–including the little ‘Bali’ cherry in my front yard, which is just starting to bloom. The magic number for a freeze is 28 degrees F.  Above that, many crops will be OK; below it, not so much. The amount of damage also depends on how long temperatures remain low.

Since my cherry is fairly small, I plan to sew together a couple of old sheets and drape them over the tree. Hopefully, that will provide enough protection to keep the blossoms in tact. Those with larger trees or orchards may try running a sprinkler on the tree during the freeze. Here’s a post from the U of M Extension on protecting crops from a freeze.
