Don't know about Iowa. Michigan took a hit.
Highs in the 50's today. Snow, freezing temps yesterday, Freeze warning tonight.
I have heard of 50 - 70% loss of the tart cherry crop, with some areas forecasting a 90% loss. The Choke Cherry trees are at about 50% bloom, but it really isn't warm enough for the bees to forage much. The few apple trees I checked had about 1/4 of the buds turning brown. I think the maples were all done in March.
Gloom, despair and agony.......
Keep your chin up! (it makes a better target
