Impact & Risks

The short growing season in Minnesota requires careful planning to maximize crop yields. Planting heat-loving crops too early, before the soil warms, can stunt their growth. Similarly, failing to protect plants from late spring frosts or early fall frosts can lead to crop losses. Gardeners should monitor local forecasts and use frost blankets or other protective measures to safeguard their plants. The limited growing season also emphasizes the importance of starting seeds indoors and selecting appropriate plant varieties.
