Sunflowers—those large, happy blooms that can brighten up any garden. People enjoy them not only for their aesthetics, but also for their delicious and edible seeds.
Sunflower seeds are one of the healthiest snacks available in terms of protein, fiber, and other nutrients. And roasting them is surprisingly easy!
But what about the rest of the process? You might be wondering how to harvest sunflower seeds, and we are here to walk you through it, step-by-step!
When Do You Know It Is Time To Harvest Sunflower Seeds?
The first thing to consider when learning how to harvest sunflower seeds is the timing. When should you do it, and what are the signs that the seeds are ready? Let’s take a closer look at the process of harvesting sunflower seeds.
Sunflowers seeds are generally ready to harvest in the very late summer months or early fall—this can be from August to October, depending on your location. The sunflowers need to mature completely and dry somewhat before the seeds are ready, which is about 10 to 20 weeks from planting.
The most prevalent sign lies at the back of the flower’s head—or the calyx—when it turns a golden-brown color.
You will also know it’s time to harvest your sunflower seeds when recognizing a few key signs in your garden, including:
- Flowers Drooping—The sunflower heads begin to droop with the weight of the ripened seeds.
- Hard, Striped Seeds—If you can see the seeds and they are black with a white stripe down the middle instead of pure white, it’s likely they are ready to be plucked.
- Leaves Turn Yellow—When the leaves and other foliage turn yellow, it’s a sign that the sunflower is on its way out and ready for harvest.
- Seed Petals Have Fallen Off—The little petals that form the soft, dark interior of the sunflower will dry and fall off when it’s time to harvest the seeds, so watch for that!
How To Harvest Sunflower Seeds?
Now comes the fun part! Harvesting your sunflower seeds might seem daunting, but it’s surprisingly simple and even enjoyable.
Let’s review some methods for getting the job done efficiently when learning how to harvest sunflower seeds, both of which involve the essential step of letting the flower head dry out.
Drying Sunflowers On The Stem For Harvest
If you leave the sunflowers alone in your garden, they will dry out of their own accord without having to make space to dry them inside. However, this means you are more likely to need to stave off the wildlife that likes to snack on sunflower seeds, too.
Try using a brown paper bag secured around the sunflower head with a twist tie to deter seed scavengers. Alternatively, cheesecloth, mesh, or netting will help, but it shouldn’t be made of a material that can suffocate the plant. In a pinch, you can even use a plastic bag with small air holes cut into it.
Once the backs of your sunflower blooms have turned brown and the seeds are hard and striped, you can remove the heads. Trim about 4 inches below the head, and strip the seeds into a container by rubbing your palm firmly over the seeds. They should dislodge fairly easily, and chaff can be blown away.
You can even rub the faces of two dry sunflowers together over a bowl to let friction do the work for you and loosen the seeds!
Drying Sunflowers Manually For Harvest
Instead of tempting wild critters by leaving ripening sunflowers outside, you can bring them indoors when the seeds are about ⅔ of the way to maturity.
Cut about 4 to 6 inches below the sunflower head, then wrap it in a brown paper bag and secure it with a twist tie. Bring it inside and suspend it upside down in a warm but well-ventilated area for a few weeks.
This lets you put your sunflowers in a safe place and monitor them at your own pace, before harvesting the seeds in the same manner—rub the seeds out into a bowl with your palm and blow the chaff away, or rub the heads together to help dislodge the seeds.
How Do You Preserve Sunflower Seeds?
You don’t even have to roast sunflower seeds immediately to preserve them. If you want to use them for planting next year, you should leave them to dry completely before storing them in an airtight jar with 2 tablespoons of powdered milk separated from the seeds to keep them moisture-free.
Alternatively, sunflower seeds will last for about 3 to 4 months in a jar within the pantry, and up to a year when stored in the fridge or freezer.
What Can You Make With Sunflower Seeds?
Sunflower seeds are some of the tastiest and healthiest snacks you can grow in your garden, and preparing them with a variety of different recipes is surprisingly easy and delicious.
Your sunflower seeds don’t need to be the star of the show when cooking or baking—you can incorporate them in several ways that might not be immediately obvious!
Try the following methods of adding sunflower seeds to many meals when harvested from your garden.
- Add To Bread.
- Bake Into Bars.
- Blend Them Into Burgers.
- Crumble Inside Crackers.
- Mix Into Granola.
- Pop Into Pesto.
- Spread Over Baked Treats.
- Sprinkle Them On Vegetables.
- Top Your Tacos.
- Tuck Within Tarts.
Apart from these clever ways to add the crunch of sunflower into a variety of your meals and baked goods, gardeners can also use home-grown seeds to create a few popular sunflower-based items. Let’s take a look at some more scrumptious sunflower seed recipes!
How To Roast Sunflower Seeds
The simplest way to prepare sunflower seeds is by cleaning them, popping them into the oven, and turning them into little roasted nutty delights.
The following method is for salted, roasted sunflower seeds—but if you don’t like having salt on your snacks, you can simply rinse off the seeds straight from the garden and roast them at the same temperature for about half the time!
- Preheat your oven to 400°F and then prepare the seeds for roasting. Take 1 cup of raw sunflower seeds that have been harvested still in the shell and 2 – 2 ½ tablespoons of kosher or table salt.
- Combine these in 1 quart of water in a saucepan and bring to a gentle boil. Then, reduce the heat to simmer the pot and allow it to cook for 15 – 20 minutes more.
- Drain the seeds and spread them onto a baking tray in one layer. Pop the tray onto the top rack of the oven and roast for 10 – 15 minutes, watching to ensure they don’t burn.
- Once they are dry and crisp enough that the shells begin to crack, you can take the sunflower seeds out and allow them to cool before storing them in an airtight container.
These roasted sunflower seeds should last for about 4 or 5 months when kept in the pantry, and 1 year in the fridge or freezer.
How To Make Sunflower Butter
For a creamy, protein-filled spread, try sunflower butter in your next breakfast. These seeds are bursting with nutrients, including magnesium, iron, and vitamins, so turning them into a healthy butter is a great idea, with the following steps!
- Shell 2 cups of sunflower seeds. This is easily done by putting them in a large freezer bag and firmly pressing them with a rolling pin. The pressure should be enough to crack the shell and allow you to pull it off, without turning the seed meat into dust.
- Roast the shelled sunflower seeds at 350°F for about 8 minutes, then remove from the oven and allow to cool.
- Add the seeds to a blender or food processor with 2 – 3 tablespoons of honey or maple syrup for sweetness, and blend until smooth. It will take a little while as the consistency changes, so blend in 2 – 3 minute intervals to monitor how runny it gets!
Serve this butter on toast, crackers, or use it in salad dressings and other sauces. You can put it in an airtight container and store it for up to 2 weeks in the fridge, or 4 months in the freezer.

How Do You Get The Seeds Out Of Sunflowers?
