Growing Tips
To 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. Mammoth sunflower seeds do best when directly sown in a full-sun location with warm, well-drained soil after frost potential is past. Provide a trellis, heavy cord or fence for young vines to climb and develop their strong stalks. Once established, these annuals offer fair drought tolerance. Huge flowers turn the heads of passersby and appeal to butterflies and other pollinators.

OEM recommended.
Style: Mineral, Pattern Name: Quart - 1 Pack
It is the OEM recommended oil for my 2017 9.9 outboard. Arrived quickly and in a sealed plastic bag. No leaks. This is 32 oz and the motor only calls for 27 oz so enough for topping up in needed.
