Cold weather in northern Michigan threatens cherry crops
After a highly unusual prolonged warm spell in the state, cold weather returned to northern Michigan putting Michigan's cherry crop at risk.
More from the Associated Press:
Phil Korson of the Cherry Marketing Institute says it probably will take another few weeks to determine the extent of the damage. But he says every time temperatures drop into the 20s, there will be crop damage.
Temperatures shot into the 80s for five consecutive March days in the northwestern Lower Peninsula. That caused trees to bloom early. But things quickly returned to normal. The National Weather Service says Leelanau County has had six nights below freezing and three nights in the 20s since the warmup.
The Michigan Farm Bureau says millions of buds froze at their most vulnerable development stage.
Growers say they hope to salvage a decent crop.
This past February, Interlochen Public Radio's Bob Allen reported on concerns about the changing climate and its effect on fruit trees in northern Michigan.
In his report, Northern Michigan fruit growers brace for a changing climate, Allen spoke with Duke Elsner. As an agricultural extension agent for more than 20 years in the Traverse City area, Elsner told Allen this past winter has been the "most bizarre winter weather he’s ever seen."
Growers were worried back in February about what happened this week, a frost after cherry trees blossomed.
Allen spoke with Jeff Andresen, the state’s climatologist and a professor of geology at Michigan State:
Andresen’s research shows an overall increase in temperatures of two degrees statewide in the last thirty years.
That’s pushing fruit trees to blossom earlier by as much as a week to ten days.
It wouldn’t be so bad if the last date of spring frost also was shifting earlier to keep pace. But it’s not.
That means the buds that produce the fruit are more exposed to the kind of freeze that wiped out the cherry crop in 2002.
Growers are tallying up the damage after the recent hard freeze.
We'll have more on how the cherry crop is doing in a story from Bob Allen on next week's Environment Report.
