This year I decided to plant some Sunflowers in an attempt to be able to harvest sunflower seeds.
I like to try and grow all my fruit and vegetables from seed, which I have been pretty successful at so I decided to grow my sunflowers from seed.
I have read that they are super easy to grow, especially if they get a lot of sun. One of the benefits of living in Southern California is we get plenty of sun year-round!
I wanted to be a little different so I decided to use Mammoth Russian Sunflower Seeds. I am not a specialist in sunflowers or a florist by any stretch of the imagination but the only difference I can tell is that the center of the sunflower (I’m sure there’s a technical word for it) is yellow instead of brown we typically see in pictures or on TV.
Did you know the Sunflower is the State flower of Kansas? Here in California, our State flower is the California Poppy. While the poppy is a beautiful flower, I think I prefer the Sunflower. I mean who doesn’t love a nice Sunflower?
How to Grow Sunflowers
The best piece of advice I can give you is to make sure you have a lot of space when planting sunflowers. The heads can reach 1 foot across and reach heights of anywhere from 7 to 12 feet.
They do like a lot of sun so be mindful of that as well. In my experience, you should see your seeds germinate within 2 weeks.
The amount of water you need is really based on your location and weather but here in Southern California, I watered mine every other day for about 15 minutes.
You might want to consult an expert in your area for a watering schedule.
When to Harvest Sunflower Seeds
Your Sunflowers should be ready to harvest after about 3 months. While that is a good point of reference it is best you wait until the head of the sunflower begins to droop, the petals start falling off and the seeds are loose.
When the sunflower is ready, cut the stem about 1 foot below the head. At this point, I use some twine to hang my sunflowers upside down in a warm dry place for about 5 days.
Removing the Seeds
Firmly rub the head of the flower where the seeds are located over a container to catch all the seeds. You will most likely collect other debris besides the seeds and that is ok. We will get rid of them before we roast them.
Soaking the Seeds in Salt Brine
Once you have removed all the seeds from the sunflowers you are ready to prep them for roasting. In a large pot, soak the seeds in a mixture of water and about 1/4 cup of salt overnight.
Depending on the number of seeds you have I suggest between 4 and 6 cups of water. If you prefer non-salted sunflower seeds simply soak the seeds overnight in water without the salt.
After the sunflower seeds have soaked overnight, place them in a colander and separate the seeds from all the other bits. Dry the seeds on paper towels for a few hours.

Have you ever tried experimenting with different planting techniques to see if it affects the size or quality of the sunflower seeds?
Great brine and bake recipe! However I have to say for growing mammoth sunflowers, if you’re growing for seed size the best way to achieve a larger seed is to plant each sunflower by itself, not clumped together. This allows each plant room to grow and produce seeds the size of my thumb!
Super great info…all the way from start to finish!! Exactly what I was looking for in one location! Thanks for sharing your knowledge.
