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 for my Cane Corso - a Power Chewer!
These are great for my large Cane Corso. He is 130+ lbs and loves to chew bones of any kind. These last a couple months for him and keep him occupied.

DO NOT BUY- HAZARD TO ANY PUP
This is the worse chew toy I’ve ever purchased. Should’ve had read more than the first couple of reviews and I wouldn’t have wasted my money. My 18 month old Lab chewed it up in just a couple of hours..she swallowed some pieces and a lot of pieces were left all over my floor. Took it away from her and threw it out immediately..definitely NOT good for chewing, please don’t waste your money. Wish I could’ve give. 0 stars but you have to place at least 1 to leave a review 😡

Not bad
I think my dog has special chewing Powers because he pretty much started chipping away at that bone on the first day with particles of the bone fragmenting so I had to take it away because I wasn't sure if he ingested any of that. It's definitely chewable. But I think he's next level. But for a regular tour or mild chewe I think this would be perfect
