(Area) Sub-freezing temperatures to start the month of May would typically be disastrous for trees, but this year exception.
The saving grace for trees during the recent freeze was a cold April. Kate Olson, ISU Extension Program Coordinator, says trees were not as developed as they would ordinarily be.
“They blossomed out late and for the most part they aren't developed to the point where a whole lot of damage could happen. You walk a fine line with the temperature. If you drop and hold into that 25 or below temperature range there could still be some damage.”
Olson says even a majority of smaller plants were able to avoid damage.
“If you are talking flower gardens, there are a lot of hardy plants that are used to having a little snow once in a while so for the most part if they are planted they are probably going to be okay unless they are really recently planted and haven't gotten a chance to get established.”
Temperatures are expected to stay cool for the rest of the week, but not expected to be cold enough to lead to permanent damage.
