How many months when the sunflower harvested?

Sunflowers are typically harvested about 70 to 100 days after planting, which translates to roughly 2 to 3 months, depending on the specific variety and growing conditions. The timing can vary based on factors such as climate, soil quality, and care given during the growing season. Harvest usually occurs when the back of the sunflower head turns yellow and the seeds are plump.
