Why Haven’t My Broccoli Rabe Formed Any Flowers?
My plants are up to my waist with beautiful leaves, but no flowers. HELP Thanks, Clarke
If planted early in the fall or late in the spring, this crop requires about 60 to 65 days from seeding to first harvest of the flower heads. If planted in the late fall harvest is usually delayed until late winter or early spring.
