About 500 acres of cauliflower are planted in New York annually. Cauliflower is a member of the Brassicaceae family which includes cabbage, broccoli and Brussels sprouts. All of these crops do well in the climate of New York, but cauliflower is produced as a fall crop to avoid summer heat which can cause heads to become soft and over-mature quickly. Heads maturing in hot weather (over 80 degrees F) can exhibit riciness, leafy heads, off color, loose heads or poor wrapper leaf development. Cauliflower is typically harvested from August through November in New York. Most cruciferous crops have similar cultural requirements and are susceptible to a common set of insects and diseases.

Recently, orange and purple varieties are becoming more common along with the traditional white forms.

2018 Cornell Vegetable Program Year in Review

2018 is behind us but we hope that our team's efforts to enhance New York vegetable production continues well beyond! This year, our Specialists gave presentations at 119 events, sharing our knowledge with 3,535 people.

We continue to conduct on-farm research to help answer the questions of our growers. The Cornell Vegetable Program managed 50 research grants and projects in 2018. We extend our gratitude to the 65 farms and organizations that offered us land, labor, and supplies to support our trials! We also want to thank those farmers that gave generous financial contributions to support our work as well.

We cannot forget to thank the 13 Cooperative Extension Associations that partnered with us this year too. We're excited to be adding Steuben County to our list of participating counties in 2019!
