  • Soil requirements: Mammoth Russian Sunflowers prefer well-drained, loamy soil with a pH level between 6.0 and 7.5. They thrive in nutrient-rich soil, so adding compost or organic matter can be beneficial.
  • Sunlight needs: These sunflowers require full sun, which means they need at least 6-8 hours of direct sunlight per day.
  • Watering requirements: Water the seeds regularly, especially during dry periods. Ensure the soil remains moist but not waterlogged. Once established, sunflowers are relatively drought-tolerant but will perform best with consistent watering.
  • Planting season: The best time to plant Mammoth Russian Sunflower seeds is in the spring, after the last frost has passed and the soil has warmed up.
  • Depth and spacing: Plant the seeds about 1 inch deep and space them 18-24 inches apart to allow ample room for growth.
  • Germination time: The seeds typically germinate within 7-10 days under optimal conditions.
  • Maturity time: Mammoth Russian Sunflowers usually reach maturity in about 80-90 days after planting.
  • Harvesting time: The best time to harvest sunflower seeds is when the back of the flower head turns yellow and the seeds are plump and slightly loose. This is usually in late summer to early fall.
  • Harvesting tips: Cut the flower heads with a few inches of stem attached and hang them upside down in a dry, well-ventilated area to finish drying. Once fully dry, rub the seeds from the head and store them in an airtight container. Use gloves to protect your hands from the rough texture of the sunflower heads.
