Michigan growers are experiencing changing weather conditions as the growing season progresses. During the week ending June 29, temperatures remained 4 to 8 degrees below normal, while rainfall varied across the state, with the highest amounts recorded in the northern Lower Peninsula.
Forecasts call for hot and humid weather, with heat index values reaching 105 to 110 degrees Fahrenheit in some areas. Growers are being advised to monitor crops closely and take precautions to reduce heat-related stress.
Soil pH management continues to be an important consideration for vegetable producers. Experts note that rainfall can gradually increase soil acidity, making lime applications an important tool for maintaining nutrient availability and supporting crop growth.
Crop development remains active across Michigan. Potatoes are flowering, and some farms have begun harvesting carrots, radishes, and beets. Early sweet corn harvest is also expected to start soon.
Michigan State University researchers recently attended the International Asparagus Symposium in South Korea, where discussions focused on global production trends, season-extension strategies, and harvesting innovations.
Pest and disease activity is also being monitored. The first aphid colonies of the season have been detected in celery fields, while aster yellows phytoplasma has been identified in some carrot and celery samples. Cucurbit downy mildew spores continue to be detected in crops affecting cucumbers and melons.
High temperatures may create challenges for vegetables such as leafy greens, brassicas, tomatoes, and peppers. Heat stress can contribute to issues including bolting, tip burn, blossom-end rot, reduced pollination, and lower crop quality.
Garlic growers are preparing for harvest and storage, while sweet corn producers continue monitoring for corn earworm and western bean cutworm activity as the migration season progresses.
