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)

Hana approved, gold star toy
Color: Original Pack, Color: Original Pack
This is, according to Amazon, our 11th set in 3 months. According to Hana, our shiba/chi mix, this toy is immaculate. Crunch score is a 10/10 and the squeak? Don't get her started. High pitched, easy to squeak and protected by just enough crunch and fabric that it actually lasts. In fact, she will tear the toy open before the squeaker gives up. This may seem like a small feat, however most toys last 12-30 minutes before the teefies take the squeaker out of commission. Lambchops last about 15 minutes before the squeaker gives in and fluff decorates the floor. The only reason we buy so many so often is because 1. The teefies do eventually puncture and the moment that happens she guts the poor Claw instantly. And 2. She has about 11 teefies, so the mouth gets kinda icky and due to the crunch, washing these kind of sucks- retains a lot of water and cant dry. So we replace them often even if she doesn't get to the gutting. 10/10. Its her favorite toy. And we've tested a lot of toys.

They are so soft and the details are hilarious! Just be careful because the pawcohol content is pretty high so I’m sure your dog will be feeling it after just one! 🤣🤣🤣🤣🤣
