Stubborn drought in Ohio and the shifting weather patterns influenced by climate change appear to be affecting North America’s largest native fruit: the pawpaw. Avocado-sized with a taste sometimes described as a cross between a mango and banana, the pawpaw is beloved by many but rarely seen in grocery stores in the U.S. due to its short shelf life. The fruit grows along the east coast of North America from Ontario, Canada, to South Florida. But in parts of Ohio and Kentucky, some growers this year are reporting earlier-than-normal harvests and bitter-tasting fruit, a possible effect of the extreme weather from the spring freezes to drought that has hit the region. Take Valerie Libbey’s orchard in Washington Court House, about an hour’s drive from Columbus. Libbey grows 100 pawpaw trees and said she was surprised to see the fruit dropping from trees in the first week of August instead of mid-September. “I had walked into the orchard to do my regular irrigation and the smell of the fruit just hit me,” said Libbey, who added that this year’s harvest period was much shorter than in previous years and the fruits themselves were smaller and more bitter. While Libbey attributes the change to heat-stress, it’s not clear if drought alone — which is gripping parts of Ohio and Kentucky for the third year in a row — or increasingly extreme, unpredictable weather are affecting the fruit. “Pawpaw growers are finding we just have to be prepared for more extreme weather events. Last year we were hit with late spring freezes that killed off a lot of the blossoms in the spring time period. This year we were hit by the drought,” Libbey said. That’s in line with the effects human-caused climate change is having on the Midwest according to the National Climate Change Assessment, a government report that comes out every four or five years. Last year's report said that both extreme drought and flooding were threatening crops and animal production in the region.
