How do you test old seeds for germination?
There are two easy tests you can take to check to see if there is life left in your old seeds. Water test: Take your seeds and put them in a container of water. Let them sit for about 15 minutes. Then if the seeds sink, they are still viable; if they float, they most likely will not sprout. via

How do you test for seed viability?
If you have large seeds like peas, beans and corn left over from last year, an easy way to test for their viability is to fill a shallow pan with water and pour the seeds in. If they sink, they're fine. If they float, toss them. via
Will 10 year old seeds germinate?
Do seeds go bad with time, or can you plant them no matter how old they are? The answer is, yes, seeds will eventually go bad and no longer germinate, but it can take quite a long time. There is a good chance that those old seed packets will have a high percentage of seeds that will germinate just fine. via
Should I soak old seeds before planting?
It is recommended that you only soak most seeds for 12 to 24 hours and no more than 48 hours. After soaking your seeds, they can be planted as directed. The benefit of soaking seeds before planting is that your germination time will be reduced, which means you can have happy, growing plants faster. via

What is seed testing method?
Seed testing is determining the standards of a seed lot viz., physical purity, moisture, germination and ODV and thereby enabling the farming community to get quality seeds. The Seed Testing Laboratory is the hub of seed quality control. via
How do you know if seeds are germinating at home?
Why is my seeds not germinating?
The primary reasons for failed germination are: Seeds get eaten – mice, voles, birds, and wireworms all eat seeds. Check to see that the seed is still in the soil. Seeds rot – planted too deeply, over-watered, or in cold weather, our untreated seeds may simply rot. via
Do seeds need light or dark to germinate?
Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007). Don't confuse seed light requirements with what seedlings need. All seedlings require sunlight. via

Accuracy
How Old Can seeds be and still germinate?
But there are a couple of factors that play into the viability of your seeds: Age — All seeds are viable for at least a year, with many others viable for definitely two years. After that, the seeds germination rate may start to drop off. via
How long does it take for seeds to germinate?
Germination speed mainly depends on the temperature of your room. The warmer the environment, the faster the germination. The best average temperature to grow your plants is 18 to 24'C (64 to 75'F). Usually it takes 1 to 2 weeks to germinate. via
Can old seeds germinate?
Seeds that are only a year old, or slightly older but whose packets are still unopened, generally germinate nicely. If they're several years old, the packs were opened and/or the seeds were stored in less than ideal conditions, subject them to a germination test. Viable seeds should sprout by day ten. via
Do old seeds grow slower?
Old seeds will result in lower rates of germination - meaning that fewer will sprout. But as for those that do sprout, generally speaking no, they do not grow smaller or slower. via
How do you speed up pea germination?
Soak them overnight in warm water. This will expedite the germination process. Each pea variety is in its own plastic container filled half full with water, so the peas are well covered. Only soak seeds for about eight to 12-hours and no more than 24-hours. via
