Erratic Spring Temperatures Challenge Chicago's Heirloom Tomato Growers
In Chicago, erratic spring temperatures are posing significant challenges for heirloom tomato growers. Bob Zeni, a seasoned gardener, has been adapting his methods to cope with these unpredictable weather patterns. He notes that temperatures can swing dramatically from 30°F to 60°F in a single day, complicating efforts to maintain optimal growing conditions. Zeni has been experimenting with natural pest control methods, such as using ladybugs instead of chemical pesticides, and employing companion planting techniques with basil and other herbs to repel aphids. The fluctuating temperatures have also led to incidents like the 2021 cold snap that destroyed 2,000 tomato plants in an unheated greenhouse. Despite these challenges, Zeni continues to innovate and educate others on sustainable gardening practices.
