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.

poli glow shine
its works great .when applying more coats the shinier it gets
i used on several old boats because
the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is
How long it will last?
What will it look like after it rains?
Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.
