Raspberries haven't blossomed
My husband planted Heritage raspberries three years ago. They have never blossomed or produced any berries. They have been fertilized, watered and cut back to the ground the last 2 seasons. They get sun except for the early morning hours when they are semi-shaded. The plants are very healthy looking but just have never blossomed. We are in South Central Mississippi. This is my first posting. Will appreciate any info I can give him.
