Kohlrabi
Kohlrabi is a minor crop in New York, but is popular at farmers markets and other retail stands. Its mild flavor makes it favorable to eating fresh and even young children like it when cut up and served like carrot or celery sticks. Both green and purple varieties are available. It is best grown in cooler temperatures and is typically available in June and July and then again in September and October. Kohlrabi is a member of the Brassicaceae or cabbage family which also includes broccoli, cauliflower and turnips. It can be susceptible to many of the same diseases and insects as other members of this family.Relevant Events

New Crop Rotation Recommendations for Swede Midge
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
New Cornell research has demonstrated that brassica crop rotations of 500 ft (down from 3000 ft) and 3 months (down from 3 years) could effectively "crash" a swede midge population when fields are secluded from each other, making crop rotation a much more feasible strategy for small farms. A new fact sheet details the new crop rotation recommendations and provides information on the pest's life cycle, biology, and crop preferences in addition to real-world examples of crop rotation. The crop rotation strategies were developed to serve the needs of small organic farmers, but have utility for conventional farmers as well.
Video: New York State Produce Auctions
Currently, there are 8 produce auctions in New York State. These auctions are aggregation points that allow local farmers to sell their produce in wholesale lots to buyers from across the region. To document the economic impact of produce auctions on agriculture, local businesses, family farms, and produce buyers, the Cornell Vegetable Program worked with Harvest New York to survey top sellers and buyers.
A new Cornell Vegetable Program video shares general information about produce auctions, how buyers and sellers use the auctions to expand their businesses, and how local communities benefit from them.
Video: Swede Midge
Swede midge is an invasive insect pest that is threatening the viability of broccoli, cauliflower, cabbage, Brussels sprouts, kale, kohlrabi and turnip production within the Cornell Vegetable Program region and throughout the Northeastern US. This short video will provide you with some general information about this pest and how to scout for it in your Brassicas.
Extending the Harvest Season with Fall Production
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program
Late season production starts in mid spring. For a successful crop, start with a detailed plan. Designate an area specific for late season production so that management can take place in one spot rather than all over the farm. This will make cultivation, pest management, using row cover, and harvesting more efficient to manage.

African Eggplant Participatory Breeding Kick-Off
March 5, 2026
Join us to learn about the Cornell African Eggplant Research Project and learn how you can participate! African eggplant, also known as Bitterball, Garden Egg, Kittley and other names, is an important crop for many members of our community with heritage from regions such as sub-Saharan Africa, Southeast Asia, and Brazil. Since 2024, the Cornell African Eggplant Research Project has been collaborating with growers and community partners across New York to develop high-quality varieties adapted to the Northeast U.S. In this meeting, we will share information about growing and preparing African eggplant, highlight our research to date, and invite partners to collaborate with us in our 2026 participatory breeding and variety selection efforts.
COST: FREE! You must pre-register to receive the Zoom link.
Managing the Invasive Swede Midge Webinar
March 6, 2026
Swede midge is an invasive fly that causes serious economic losses to brassica crops. Due to its small size and hidden feeding habits, swede midge is often called an "invisible pest" and damage may be misdiagnosed. In this webinar, we will review the swede midge life cycle and crop damage symptoms, current management recommendations, new research findings, and highlights from on-farm case studies with a focus on organic management.
1.75 DEC pesticide recertification credits in categories 1a, 10, and 23.
