An erratic spring continues. A warm day, and the buds swell on the blooming trees and bushes. But the next day its cold and snow coats the green grass. Predictions are for a hard freeze that night. If only there was a way to stop it. The crabapples, the red bud trees, the Bradford pears, the flowering almond, the lilacs--all are vulnerable. A hard freeze would mean we'd have no blooms until next year. Not a happy thought.
