Mistakes to Avoid When Harvesting and Roasting Sunflower Seeds
Haste Makes a Mess of Things
Horrors! This is the fully illustrated not-to-do guide for a neophyte’s foray into sunflower food production. Whether for birds or humans, you want seeds which look like the ones you formerly purchased at the grocery or the feed store. Now that you are a sunflower gardener, do not be impatient or cut corners. Here is what may happen…
Sunflower Blossom Looks to the Sun
Mistake Number One
It is too early to cut this flower head (see above photo). The petals are still gloriously waving like a corona around the flower. Wait until almost all petals off.
Green Calyx Does Not Mean "Go"
Mistake Number Two
This one is still too early to cut, kind of… The general wisdom is that the back of the flower’s seed disk (called the calyx) should be all yellow-brown and drying out. The lovely and lively green as illustrated means the seeds are not mature, meaning not tasty and good for eating.
Immature Seeds of Sunflower Blossom
Mistake Number Three
Picking a sunflower with totally white colored seeds rather than black stripes on white means the seeds are not mature.
When to Cut the Flower?
I will cut my seed heads a little on the early side because the birds in my neighborhood organize themselves marvelously, with 24/7 surveillance on the progress of the seed maturation.
If I wait until the back of the flower is the proper shade of drying out, there will be no seeds left on the reverse side. Yes, one can cover up the flower head with a cheesecloth or paper bag to prevent fly-by avian diners from taking the seeds before the human gardeners get them. But, I did not want to be bothered. So, maybe that should be illustrated by mistake number four.
Mistake Number Four
Neglecting or forgetting to put bags over the flower heads to protect them from birds.

Mistake Number Five
Flower heads piled on top of each other to dry inside the garage, basement, or house prevent moisture from evaporating. Then all the flowers can become moldy. Eeyuck!
Mistake Number Six
If you are shelling the sunflower seeds before you roast them (which is an acceptable way to prepare them), trying to do it before the seeds are dried out enough is another mistake.
The insides will be like squishy white potato.
Mistake Number Seven
Cooking on too high a temperature. Whether you are roasting shelled or unshelled seeds, the common wisdom is to cook them at 300 degrees F for 30 to 40 minutes.

Questions & Answers
What if you cut the sunflower flowers off too early? I do not want to eat the seeds, only plant again next year. Since the seeds are not ready I’m guessing my sunflowers won’t grow?
That's usually the case. You need to allow the seeds to fully mature.Helpful 31
I had a beautiful sunflower fall over and snap because the head was so heavy forming seeds. The head was pointing down, the petals are mostly gone but the seeds are all white. Also, the back and stem are still green. I have put it in water for now - can I do anything with my sunflower to let it finish ripening or is it over?
I would say for purposes of growing new plants next season, so not count on these immature seeds. You can put them in the ground for purposes of composting in place, but get new, mature seeds to grow.Helpful 21
Can the sunflower head ripen if you harvest too early?
This is the first time I have ever grown the mammoth sunflower. I was googling when to harvest, but because I was so anxious about the pests getting it, I cut it too soon and the seeds did not form the black and white coat yet. Is there something I can do to let the head mature a little more so it grows the shell properly?
You can try keeping it in a dry place, but it sounds doubtful.Helpful 46
Why did some sunflowers from the same package of sunflower seeds produce all black seeds, with only a few black and white?
My guess is that a few black seeds had been inside your package. All black seeds have more bird food nutritional value.Helpful 14
