Sunflower Mammoth Seed
Color: Brown centers surrounded by yellow petals
Growing TipsTo ensure your Mammoth Sunflower seeds grow to be tall plants, remove weeds with the help of a natural mulch. Using mulch also helps retain soil moisture and heat. Use shredded leaves as an organic mulch for your Giant Mammoth Sunflower seeds to improve soil quality. Always keep mulch away from the flowers' stems to prevent possible deterioration.
To harvest your Mammoth Sunflower seeds for sale or eating, cut the head off after the stalk dries but before fall or winter rain arrives. The flower is ready for harvest when the florets in the center wilt and the back of the flower head is turning yellow or starting to droop.
