WASHINGTON — Despite the long, snowy winter, Washington’s famous cherry blossom trees are expected to bring the first sure sign of spring between April 8-12, when they are predicted to reach peak bloom, the National Park Service said Tuesday.
The weather in March will be the most critical factor for the trees’ blooming period, said James Perry of the National Park Service.
‘‘Relax and let Mother Nature take her course,’’ he said. ‘‘This has not been the coldest winter on record or the snowiest. These trees have been around for 102 years, so we know pretty well how they’re going to react.’’
About 70 percent of the trees around the Tidal Basin must be in bloom with pink and white flowers for the park service to declare peak bloom. Tree workers will be looking for the first sign of green buds, monitoring the forecast, and reviewing records to update Perry’s prediction, he said.
‘‘The colder it is, the slower the process will be,’’ he said. But there has not been any significant damage from the recent snow and ice, he said.
