Sunflower seeds will retain their best quality for about 12 months, but will remain safe beyond that time.

Will 2 year old sunflower seeds grow?
Yes. Plants grown from expired seed packets will grow to produce healthy and fruitful harvests, just as they would from fresh seed. You can check the expiration date on your packet by opening it up and looking at the date printed on the back of the packet.
If you see the word “EXPIRED” or “EXCESSED” printed in large letters, it is most likely expired. If the label is still legible, then you can assume that your seed is safe to use. However, if you do not see any of these words or stickers, you should not use the seed in any way, shape, or form.
Do sunflower seeds go bad?
Sunflower seeds do go bad and don’t last long in the pantry but remain great for a long time if you want to freeze them. The raw seeds are usually in the pantry for 3-6 months. It will take about a year in the fridge or freezer.
Can I grow sunflowers from last years seeds?
After a sunflower has flowered its seeds can be harvested for planting again the following year. A single seed planted in the spring can produce many seeds in the autumn and these can be taken from the seed head once a year to be used for the next year’s crop. Sunflowers can also be grown from seed, but this is not as easy as it sounds.
First, the seeds must be germinated. This is done by placing a small amount of water on the top of the plant and letting it sit for a few days. The seeds will then begin to sprout. Once the sprouts have sprouted, they will be removed and placed in a bag and allowed to dry for several days before being placed back into the soil.
They will continue to grow until they have reached a height of at least 1.5 metres (5 feet) and are ready to harvest. Harvesting is usually done in late summer or early autumn when the sun is at its highest point and the weather is warm enough to allow for good germination.
How do you store sunflower seeds for planting?
If you’re saving the seeds to re-plant, store them in an airtight container in a cool, dry place until you are ready to plant. The container should be labeled with the variety and the harvest date. The seed will last a long time if it is stored this way. Before planting the seeds should be dried for several hours or overnight.
Can you plant raw sunflower seeds?
Sunflower seeds in the shell are better for growing microgreens, but raw seeds, both hulled and unhulled, work just as well. Soybeans are a good source of protein, fiber, vitamins, minerals, and phytochemicals. However, soybeans contain a high amount of phytic acid, which can cause digestive problems in some people.
Soybean oil is also high in saturated fat and cholesterol, making it a poor choice for people with heart disease or high blood pressure. Avoid eating soybean products such as tofu, tempeh, natto, miso, edamame, or soy milk, as these products contain high amounts of soy protein isolate and soy lecithin.
Do you plant sunflower seeds point up or down?
Sunflower seeds will sprout best if you plant them with the narrow pointed seed-end facing down. It isn’t necessary to do this, but it does give the sunflowers the best chance of germinating. If you want to plant your sunflower seedlings in the ground, you’ll need to make sure that the soil is moist enough to allow the seedling to grow.
If it’s too dry, the seeds won’t be able to take root and the plant will wither and die. The best way to ensure that your soil has the right moisture content is to use a soil test kit. These kits can be purchased at most garden centers, or you can order them online from your local garden center.
