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)
