Will outdated seeds germinate?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 long do seeds take to sprout?
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
How do you revive seeds?
Should I soak pumpkin seeds before planting?
Most giant pumpkin seeds have a very thick seed coat. You'll get better germination if you file the edges of the seed. After filing, soak seeds for an hour or two in hot water before planting. These steps help seedlings to emerge easily from within the hard seed coat. via
Should I soak nasturtium seeds before planting?
Some gardeners like to soak nasturtium seeds before planting to speed germination. If you do, remember to soak them no longer than eight hours to avoid losing your seed to rot. Nasturtiums like sandy, well-draining soil without too many nutrients, but they do like ample water. via
Should I soak spinach seeds before planting?
About a week before planting, soak spinach seeds in room temperature water for 24 hours. Shift the seeds to an airtight container, and keep in a cool place for up to a week. The primed seeds will retain enough moisture to complete the first two stages of germination. via
Are egg cartons good for starting seeds?
Egg cartons – Egg cartons work well for starting seeds, but you'll have to transplant them to larger containers as soon as they've sprouted. Old shoes, hats, baskets, etc. – Get creative! You can use anything that can hold soil, as long as it has drainage. via
How do you start seeds indoors?

Spinach seeds not germinating – If your seeds never germinated, then it was either too wet, too warm, or the seeds were old, and no longer viable. Always plant fresh spinach seeds in well draining, cool soil for best results. via
What causes seeds to germinate?
All seeds need water, oxygen, and proper temperature in order to germinate. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo's cells start to enlarge. via
Do seeds need sunlight to germinate?
All seedlings require sunlight. Seedlings will become leggy and fragile and will not produce to their potential if they do not have sufficient light. Table 1. Soil temperature conditions for vegetable crop germination. via
What is the longest lasting seed?
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. The ancient seed was found along with several others in the 1960s in the Masada fortress on the edge of the Dead Sea in Israel. via
How long do seeds last in packets?
Most vegetable seeds remain good for about two to three years, but some, such as onions, deteriorate within a year. Lettuce, on the other hand, can successfully sprout after five years. via
How do you know if a seed is viable?
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. via
How do you test for seed germination?
The Germination Test
First, take a paper towel and moisten it with a spray bottle. Place 10 of the seeds to be tested onto the paper towel, then carefully fold the wet paper towel over the seeds. Place the paper towel and seeds in a plastic bag, seal it, and label the bag with the variety and the date. via
What can I do with old seed packets?
