BRIDPORT, Vt. — An abrupt swing from hot weather to cold across the Northeast is frustrating some flower and fruit farmers who have had to either harvest blooms extra early or fear they could lose some crops altogether.
Frosty nights aren't unusual this time of year. Across the region, the average date of the last frost ranges from mid-April to early June, according to the Northeast Regional Climate Center at Cornell University. But the first half of April was unusually warm for much of the region, and that, coupled with the quick drop in temperature, could cause some problems.
Boston saw temperatures climb into the high 70s (around 26 Celsius) last week, with cities including New York, Philadelphia and Washington, D.C. reaching temperatures in the 90s (around 32 Celsius), according to the National Weather Service. By the weekend, temperatures across the region dropped into the 50s (around 10 Celsius), with some areas in New England seeing snow showers.
And the cold continued into this week: The National Weather Service issued a freeze warning for Monday night and Tuesday morning for parts of Ohio, Pennsylvania, Virginia, Maryland and North Carolina.
In Ohio, the warm weather pushed peach and apple trees to start budding early at Apple Hill Orchards, which includes about 80 acres (32 hectares) in Mansfield and 110 acres (45 hectares) in Fredericktown. But the temperature then dropped into the low 20s (around minus 5 Celsius), ruining one variety of peach, said owner Anne Joudrey.
“Farming is farming, and you never know what you’re gonna get, but we had a pretty good bloom, so we were expecting a pretty good crop,” she said Monday.
The apples were doing OK, she said, and it helps that the trees are planted on high ground so cold air drains away.
“We should fare pretty well, hopefully,” she said. “But you never know.”
In Vermont, the temperature swing affected operations at Understory Farm in Bridport, which grows cut flowers. Tulips that were supposed to be ready for Mother's Day in mid-May have already bloomed in the farm's greenhouses, said owner Gregory Witscher.
“That just means that we have to harvest them all at the same time,” he said. “We have to harvest them and store them with the bulbs on in crates in a walk-in cooler for longer.”
Witscher grows about 50 varieties of flowers for wholesale markets. Weather fluctuations require flexibility, he said, and it's become more common for small vegetable and flower farms to have row covers or heaters to protect plants from cold or shade cloth for extreme heat.
“With the hot weather and then the cold weather, I think it's intense, and it makes things challenging,” he said. “The longer I do this, the more I want to have as many options as possible and have a lot of tools and resources available to be extremely nimble.”
