The water test is a method to check for viability. Put the seeds in a container of water. The seeds need to sit for 15 minutes. If the seeds sink, they are still viable, but if they float, they probably won’t grow.
Another method is to soak the seedlings in water for a few hours. The seeds should float to the surface, but they should not be completely submerged. Seedlings that are soaked for long periods of time are more likely to die than those that were not soaked.

Will 20 year old tomato seeds grow?
If tomato seeds are appropriately fermented, dried, and stored, they can last up to 10 years with a germination rate of 50%. The rate will be even better if it is used within 4-7 years. Heirloom tomato pioneer Carolyn Male has re-awakened 22-year-old tomato seedlings that had been inactive for more than two decades.
Tomato seeds can be stored in a cool, dry place, such as an airtight container in the refrigerator or freezer. They can also be kept at room temperature for a few days before using.
Will 10 year old seeds germinate?
Even seeds that are thousands of years old can germinate. The older the seed, the less energy it has left in storage, and proper pre-treatment is essential. It’s difficult to grow seeds from annual plants because they aren’t designed to last many years. It depends on what you’re looking for.
If you want to know how old your seeds are, you can look at the date stamp on the package. This will tell you how long it’s been since the seeds were last stored. For example, if your package it was stored in the U.S.A. for one year, that means that it hasn’t been stored for more than a year.
You can also check the expiration date of your seed by looking at it under a magnifying glass. The date is usually printed on a small sticker that is affixed to the outside of the packet. Look for the word “expiration date.” If it “1 year” or “2 years,” then you’ve probably got a good one.
Should I throw away tomato seeds?
If you’re adding tomatoes to a salad, salsa, omelet or casserole, you should scoop out the seeds with a spoon. They can ruin the consistency of the rest of your meal by making your dish extra watery.
Can I use tomato seeds from last year?
Tomato seeds remain viable for years, even stored at room temperature. You can keep them in the refrigerator or freezer, but make sure they come to room temperature before opening the jar because you don’t want the seeds to get wet.
Are 20 year old seeds still good?
It’s true that seeds don’t expire. They lose their viability if they are not properly stored. If you keep the seeds in a cool, dark, well-ventilated area, they will keep for decades and will grow when replanted. The best way to store your seeds is to keep them in an airtight container with a tight fitting lid.
This will prevent the seeds from drying out, which can lead to mold and fungus growth. You can also place the container in the refrigerator for a few days to allow the moisture to evaporate. If you are storing seeds for longer periods of time, you may want to consider using a plastic bag to protect the seed from moisture.
Can I use seeds from 2 years ago?
For at least a year past the season for which they were packaged and may be good for several more years, seeds that have been stored in a cool, dry place are generally viable.
Should you soak tomato seeds before planting?
It’s not necessary to soak your tomato seeds before planting. It is possible that it is a way to speed up the process. If you want to make sure your seeds germinate as quickly as possible, you can soak them in water for a few hours.
You can also soak the seeds in a solution of 1 tablespoon of baking soda and 2 tablespoons of water. This will help to loosen the seed coat, which will make it easier for your seedlings to sprout.
