What temperature is needed to make my Forsythias bloom?
My Forsythias are still naked, but they are covered in gorgeous buds. What temps are needed to make them bloom their gorgeous yellow?
I figure they haven't bloomed yet because they're scared to, because our winter here has sucked! I don't let my kids use that word, but really, it is applicable.
300 inches of snow, TWO blizzards So, are mid 40 temps enough to make these shrubs bloom?
