Authors: Natalie Hoidal and Marissa Schuh , Extension Educators, University of Minnesota Extension. Originally published 2021, updated 2025. We are reviving and revising a series of crop-specific deep-dive articles we published in 2021. This week we are focusing on crops in the Brassica family, and tips for growing them successfully. By planning ahead and anticipating challenges, you can get ahead of common problems that limit yields. Bolting Brassicas originated in the Mediterranean, where they were originally biennial plants that required a 2-3 month cool period (winter vernalization) to induce flowering. Since winter in Greece is a bit like spring in Minnesota, growers in cool climates have been able to grow Brassicas in the spring. Because our spring is followed by a very warm summer, growing spring Brassicas in Minnesota can be a bit of a dance with the weather. While each plant is a bit different in its requirements, the basic idea is that they prefer conditions in the 60s early ...

Madeline Wimmer- Fruit Production educator Introduction Whether you’re working on a new vineyard block, elongating cordons for further established vines, or replacing winter-injured or declining cordons, tying down canes to fruiting wire is something all vineyards end up doing annually. Tying new grapevine canes is a critical step across many training systems and vine situations. This process is fairly simple, and below are a few tips and answers to common questions to ensure your success! Images: A Vertical Shoot Position (VSP) trained grapevine with a permanent cordon on one side, and a cane tied down on the other to replace a cordon (left). A grapevine cane with newly swelling buds (primary and secondary) developing (upper right). A grapevine cane that is being tied down to elongate the short, already-established cordon (lower right). Why is it necessary to secure canes to the fruiting wire? Without any support, the cordons (i.e., the arms of the grapevine) would collapse from the w...
