Sowing Instructions

DIRECT SOW IN FULL SUN WHEN SOIL TEMPS ARE ABOVE 60°F

Starting Indoors

6-10 WEEKS BEFORE LAST FROST

Growing Tips

Direct sow your seeds in the garden when soil temperatures are between 60-70°F. Transplant from indoor starts when soil temperatures are around 70°F. Plant multiple seeds outdoors or in each cell (indoor starting) and thin to the most successful plants.

We tend to plant Sunflowers at random without thinning and allow them to establish on their own without intervention.

Culinary Uses

Mammoth Grey Sunflowers are known for their large heads and numerous seeds. The seeds harvested are usually roasted, salted and eaten as a snack. Birds also love sunflower seeds, so do not be surprised to see them stealing your seed crop.

Harvesting Seed

Harvesting sunflower seeds can be fun for everyone. Wait until the sunflower petals start to wilt and fall off the sunflower head. The head should start to become dry and brown and may even start to fall over.

Once the heads start to become brown, place a paper bag upside-down over the head of the sunflower. (This protects your seeds from birds and squirrels).

Check your sunflower heads daily to see if the seeds have become hard. Once the seeds are hard enough to harvest, cut the stem of the flower and hang it upside down to dry thoroughly. Once the heads and seeds have dried enough, running your hands back and forth over the seeds will release them.

Roast your seeds as a snack or save them for next years harvest. (We recommend saving your seeds from the first harvest to produce hundreds of plants the next year)

GREAT product!
I have had mechanical wine openers before and found them to be more annoying and more time consuming than just using a traditional corkscrew. NOT the case w/this one. So.... 1. display: the charger station is small enough in size that it would fit in most any location w/o taking up too much space. For those that do not like clutter or one more "gadget" to sit out, this is a good size. The charging station has a little holder for the foil cutter as well which is great and keeps all parts together so no one has to search drawers when ready to open the bottle. There is a blue light that glows while being charged and is very pleasant to look actually and is a nice touch. so it actually looks really good sitting on top of the wine rack. Mine happens to be right next to an electrical plug on the wall so does not reveal the hanging cords or wires. 2. function: works great so far and have opened quite a few bottles. very easy to use. would suggest holding the bottle by the fatter part toward the middle and then using the other hand to work the corkscrew. does not work well if the bottle sits on the counter unless you have a good solid grip on the base. Its actually easier to just pick up the bottle and do it that way. of course that's after using the foil cutter which gives a perfect cut and removal each and every time. 3. battery life: i think the product says it can be used for 30 bottle openings during a single charge. that is quite more wine that most people would be going through in an evening so i don't think anyone would have an issue w/keeping a charge. I use it and then put directly back on the charging station as i do my mechanical salt and pepper grinders. that way, its always on the cradle and charging. as mentioned there is a blue light that glows in the actual item while its charging and i like the way it looks so would have no reason to keep it off the charger anyway. this also makes a GREAT gift especially a house warming gift to anyone who drinks wine or entertains

Great but had a problem
It’s great except you have to finagle the darn thing for it to charge. Sometimes I have to use something to get it to lean just right so it charges. Otherwise it’s spectacular and easy to use! Love the foil cutter tbh, that works like a gem!
