Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.
How long do pea seeds stay good?
3 years
Seed Viability Chart

How do you identify good seeds?
Good seed is pure (of the chosen variety), full and uniform in size, viable (more than 80% germination with good seedling vigor), and free of weed seeds, seed-borne diseases, pathogens, insects or other matter. Seed should be properly labeled.
What are the 4 methods of testing the viability of seeds?
Indirect Tests of Viability
- Cutting test. The simplest viability testing method is direct eye inspection of seeds which have been cut open with a knife or scalpel.
- Topographical tetrazolium test.
- Excised embryo test.
- Radiographic methods.
- Hydrogen peroxide.
- Authenticity.
- Damage, health.
- Purity.
Will old pea seeds germinate?
Yes! Even seeds that are thousands of years old can germinate. But proper pre-treatment is essential, and the older the seed, the less energy it has left in storage. Seeds from annual plants aren’t often designed to last many years, part of what makes the germination process so tricky.
Are 20 year old seeds still good?
The truth is seeds don’t expire. They lose viability if stored improperly. While most seed companies will tell you to replace seeds every 2-3 years, those seeds will keep for decades and will germinate when planted if kept in a cool, dark, and dry place.
Why won’t my pea seeds germinate?
ANSWER: Bear in mind that pea seeds germinate quickest in warm soil, so if it’s a cool spring, your seeds may just need a little more time to sprout. If the soil is 38 degrees Fahrenheit, expect your seeds to take 21 to 30 days to sprout, whereas in soil that is 65 to 70 degrees, they’ll sprout in 7 to 14 days.
How do you tell the difference between a good seed and a bad seed?
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.
Do good seeds sink or float?
One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.
What does a healthy seed look like?
Healthy seeds boast a slight shimmer on their shells, as though growers have polished them with some wax. Unhealthy seeds look dull and matte in comparison. If you have the choice, opt for waxy seeds with a sheen to improve your results.
What is the truest indicator of seed viability?
The most accurate test of viability is the germination test and this will be described here. The germination test is made under controlled conditions to find out how many seeds will germinate and produce normal seedlings which could develop into normal reproductively mature plants.
What is the most common test used to determine seed viability?
quick germination test
Tetrazolim chloride seed testing: The Tetrazolium Chloride (TZ) test is often called the quick germination test. It’s a chemical test used to determine seed viability, and results are usually available within 24 to 48 hours.
What is the easiest method of seed testing?
A Simple Germination Test for Seeds
- Sow seeds onto moistened paper towels to monitor germination rates.
- Bag up your test seeds but check them regularly for signs of germination.
- 100% germination is nice, but not essential.
- Don’t waste your sprouted seeds – eat them!
Do pea seeds need soaking before planting?
Most of them have hard coats, and all benefit from soaking before planting. 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.
Should you soak pea seeds prior to planting?
Yes, soaking the amount of pea seed you wish to plant in your garden in a cup of lukewarm water overnight will help the seed to absorb water and shorten the amount of time they need to germinate.
Do pea seeds need warmth to germinate?
Peas Love Cool Weather. Plant Soon For A Spring Crop!
Optimum soil temperature for pea germination is 40 to 70° F. If the soil is too cold (below 40 degrees), seeds take much longer to germinate and may rot. If soil temperatures are too high, germination stops.
How do you know if seeds are rancid?
You can tell that your sunflower seeds are rancid when they start to taste bitter or sour, perhaps reminding you of rancid olive oil. The seeds might also give off a chemical smell similar to putty or nail polish remover, but that’s not always obvious.
How do you rejuvenate old seeds?
5 Tips For Germinating Old Seeds
- Dilute 10ml (roughly one tsp) of Fulvic acid per litre (33 oz) of water.
- Scuff the outer shell of the seed with some sand paper.
- Use a lightly carbonated water.
- Use a light enzyme or seed booster, Plagron Nutrients has a very good one.
Can seeds last for 2000 years?
Forget cryopreservation – hot and dry conditions might be all you need to awake far into the future. A date palm seed some 2000 years old – preserved by nothing more than storage in hot and dry conditions – has germinated, making it the oldest seed in the world to do so.
Do peas need darkness to germinate?
Light and Pea Seeds Germination
Plant the peas in a full sun location, according to the The National Gardening Association. Peas need at least 6 hours of direct sunlight once the seedlings emerge from the soil to encourage the pea plants to produce their own food through the process known as photosynthesis.
How long does it take peas to germinate from seed?
between 7 and 14 days
Space rows of peas at least 18 inches apart. Time to Germination: Typically germination occurs between 7 and 14 days.
