Growing Broccoli in Cold Winters
This was a customer question that I couldn’t answer on the day, as I’ve never had to try and grow vegies in less than subtropical temperatures.
Question: Do broccoli plants grow in a very cold and snowy winter?
Answer: Plants will tolerate frosts and can survive below freezing temperatures (online sources say from -1 to -6C) but may be stunted and/or set broccoli heads earlier than normal. For best crops, they should be covered with insulation (mulch for small plants, cardboard boxes or plastic buckets for larger ones) to protect them from the worst of the cold.
