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.

Great tool for tire plugs
I have been using tire plugs with great success for decades. I have probably installed close to 50 plugs. The hardest part can be reaming the hole to the proper size to get a plug installed. I have wanted something like this for years. These are well made, and while I have not had to use them yet, I have no doubts they will work great the next time I find a screw or nail in a tire.
Recommended.
