Fruit growers watching weather
Cold spell could yet doom promising orchard crops
With tart cherries past their full bloom, any long-term drop in temperature below 30 degrees Fahrenheit could spell disaster for a crop, said Robert McMullin of McMullin Orchards in Payson.
From now until harvest, the orchards are critically sensitive to the weather, McMullin said. But with temperatures alternating from cold to hot and wet to dry, spring weather in Utah can be an unpredictable obstacle.
"We hold our breath this time of year because the fruit is past full bloom," said Adrian Hinton, a fruit agent for the Utah State University agricultural extension office.
Though Monday was warm, Hinton said that temperatures can still drop before summer heat sets in.
"Typically, by Mother's Day we are out of danger," Hinton said. "Unless there is a real freak cold snap."
According to meteorologists at KSL, the upcoming forecast calls for highs in the high 70s for the next two days. By Thursday, temperature will drop to the low 60s — meaning that nighttime temperatures could dip into the 30s.
Dean Miner, a county director for the Utah State University agricultural extension office, said that tart cherries can withstand temperatures down to 27 degrees for up to an hour. Hinton is crossing his fingers that it won't get that cold.
Even the recent rainstorms haven't hurt orchards, since the rain fell after the blossoms were pollinized. (Tart cherries are self-pollinized.)
"The rainfall hasn't hurt anything," Miner said. "There's not been enough hail or heavy rain to damage the blossoms."
Only a few orchards in northern Utah have reported any significant frost damage, Hinton said, since most commercial producers use warming fans to counter cold temperatures.
Miner said that Utah County is doing well, which is important since the county grows 80 percent of all fruit in the state. While tart cherries lead — although they are adistant second to Michigan's No. 1 position as a national tart cherry producer — apples rank second in fruit production, Miner said.
