Planting Instructions for Best Results

Follow these steps to grow your Mammoth Sunflower Seeds for Planting:

  1. Prepare the soil by ensuring it is well-drained and nutrient-rich.
  2. Plant seeds ½ inch deep and 12-18 inches apart.
  3. Water regularly until germination occurs within 14-21 days.
  4. Provide full sun exposure throughout the growing season.
  5. Expect large bloom sunflowers within 80-100 days.

For best results, choose a location that receives at least six to eight hours of sunlight per day. Sunflowers thrive in full sun, and their growth will be stunted without adequate light. Regular watering during the early stages of growth is important, but once the plants are established, they become quite drought-tolerant. Fertilizing the soil with compost or organic matter can also help boost growth and ensure healthy blooms.
