All seeds will eventually get "old", as it is actually a living organism. Sunflower seeds can successfully be used after they are more than 6 years old.
Can a 14 year old take fenugreek safely??
There's no specific shelf life for whole sunflower seeds. People have germinated sunflower seeds that are more than seven years old. Generally speaking, seeds that are less than two years old will have the greatest chance of viability.
You can make them into a necklace, for starters.
* Lettuce seeds will only germinate if given light and kept in 18-20 degrees * Seedless watermelons grow from seeds * A few thousand-year-old wheat seeds were found in the desert and germinated
Seeds may not germinate as expected due to factors like improper planting depth, poor soil quality, incorrect watering, inadequate sunlight, or old or low-quality seeds.
It is because the seed might be too old or you overfed the plant and that is why it did not germinate
99% of fresh seed will germinate; however, sometimes there are plants which either produce infertile seed which will not germinate. Alternatively the seed which has been sown is very old and has already died or has been damaged by insects or other storage pests.
Pepper seeds may not germinate due to factors like improper temperature, insufficient moisture, poor soil quality, or old seeds. It's important to ensure the seeds are planted at the right depth, kept consistently moist, and provided with adequate warmth for successful germination.
Almost all seeds will still be viable within one year if stored in cool, dry conditions free from pests. Seeds that last around one year are chives, parsnip, mint, rhubarb, and rosemary. On average, seeds will last 3-5 years. The longest lasting are pumpkin, squash, cucumber, silver beet, some beans and corn.

Not likely. Food poisoning usually is a result of: # The consequences of ingested enterotoxin # The consequences of ingested bacteria that produce toxins, but do not invade the mucosa, and are usually quickly cleared by the immune system Sunflower seeds do not contain any enterotoxins or compounds that can possibly degrade into enterotoxins in significant amounts, this rules out the possibility of #1. Since sunflower seeds are dry (and will likely dry further in the open), bacterial and fungal growth is nil even in the 10-year period, and this rules out the possibility of #2. Therefore, unless the sunflower seeds are in contact with a contaminated area or is in a very humid environment, they will likely cause no problems upon consumption (other than tasting stale).
