Roman Pasichnyk, the director of Seven Fields Farm, has highlighted the challenges of growing lettuce in open ground due to fluctuating weather conditions, especially heat and drought, which resulted in the loss of nearly two hectares of iceberg lettuce during late June. The extreme temperatures impede the plant's ability to absorb calcium, subjecting it to stress. To combat early spring frost, the farmer uses agrofiber to protect the plants. However, growing lettuce in the summer poses significant difficulties, with farmers in the Kherson region avoiding cabbage cultivation due to pest issues.
