Hardiness Zone: 6a

Most of the country has had an extremely long and harsh winter season this year. I had lilacs in Nevada before I came to Florida, and each spring we had another freeze just about the time the lilac buds were forming. Of course, the buds froze too, and turned black. All the leaves on any trees that had budded out also froze and turned black. If even your overnight temps dropped to near freezing, that will happen, and it also affects fruit trees the same way.
