Greek vegetable growers are facing challenges as they plan to sow their fields, including unstable temperatures, potential disasters, labor shortages, and irrigation issues. They are planning to grow tomatoes, peppers, eggplants, and other vegetables primarily for the summer season. Some farmers are using low greenhouses to protect from spring frosts. The start of planting may be delayed due to expected rain and low temperatures, and there has been a slight increase in seedling prices due to increased production costs.
