Seeds Not Sprouting Properly? Do a Germination Test
Planting any kind of seeds requires some effort, you hope the seed are viable and that they will germinate. Take the guess work out of seed germination, try this simple test to see if your seeds are still good before planting them in the garden…..
Just because the seeds look good and they have been stored properly doesn’t always mean they will germinate. Seeds will only germinate and be productive if they’re viable.
Seeds Not Sprouting Properly?
Read on as there is an easy seed germination test that you can do at home to determine viability. This type of test is especially helpful for tomato seeds. Since tomatoes are a huge garden crop so it is important to know your viable rate before starting your seeds either indoors or out.
This simple test will eliminate all the waiting and wondering after the seeds have been planted in the soil. All you need are some seeds, plastic baggies and paper towels to conduct this simple DIY germination test.
Germination Test
Conduct this seed germination test 4-6 weeks before planting season. That will allow plenty of time to start the new seeds indoors to see if they grow and then to replace them if they do not pass the test.
You will need paper toweling, sealable sandwich bags, a marker, and seeds for this DIY project. (Make sure to always read the seed package as they are usually full of great information.)
Easy seed viability test:
- Dampen 1 paper towel and spread it out on a flat surface.
- Place 2-4 seeds of the same plant variety on the damp paper towel.
- Depending on their size, separate them out and then fold the towel up, being sure the damp paper towel covers the seeds and that it is small enough to fit inside the small plastic bag.
- The damp paper towel allows water to permeate the seed coat which surrounds the seed embryo it kick off the germination process so they start growing.
- Write on the outside of the bag the date and type of seeds.
- Use a separate sandwich bag for each seed variety.
- Seal the plastic baggie, and place a warm area that is not exposed to direct sunlight.
Seeds that are viable will start to sprout within 2-14 days when kept at room temperature or a slightly higher temperature. Cold temperatures will delay germination. (if in doubt, you can always use a soil thermometer or regular thermometer to test the temperature.)
Wait 3 days and gently remove the paper towel from the bag and unfold it.
Check for Signs of Life:
Check the seeds for swelling of the seed coat or for any tiny sprouts. If you see visible signs of germination, the seeds are viable and are good for planting. You can actually go ahead and plant these little sprouted seeds! This will get a jump on planting for you.
If there’s no change in seeds, re-dampen the paper towel and re-seal it back inside the bag or covered dish and wait another 3 days. Continue to check at 3-day intervals for signs of germination.
If after 14 days the seeds have not germinated, it’s safe to assume they are not viable and should be discarded.
Viable seeds will vary in their germination time so be patient. Germination of beans and peas occurs within 2-3 days, whereas okra and carrots require the entire 14-day period for germination.
Germination Rates:
If you want to know the exact percentage for the germination rate, use 10 seeds per plant variety.
The math is easy to do, when one seed sprouts out of the 10, you have a 10 percent germination rate. If 5 of the 10 seeds sprout, you will have a 50 percent germination rate. To get a 100 percent germination rate, all your seeds must sprout! So, when you get 100% germination, you have a fantastic success rate!
The higher the germination rate, the better but anything over 50 percent is good. Under 50 percent is still okay to plant (as long as the rate is not 0), just plant extra seeds to ensure you get the desired harvest.
Variables in Your Test:
Several variables can hinder the seeds from germinating. The seeds may be too old although they usually only store well for 2-3 years. The seeds may have been stored improperly where it was too hot or too cold.
Additionally, the soil conditions may have been too low. It is also possible that there were pest issues pests with the seeds during storage or after planting.
Seed Saving
To save seeds from one season until the next. Start by allowing the flower or vegetable to remain on the plant until it has passed its prime.
Once the seeds, new seed heads or pods start to dry, collect the seeds and evenly spread them in a single layer in a warm, dry area for 7-10 days.
store dried seeds in envelopes:
Place dried seeds in a paper envelope and write the plant name on the outside of the envelope. Store in a cool dry location where the temperature will remain consistently above freezing and below 80F.
Seeds are truly amazing things. They have the power to grow into beautiful and productive plants, providing us with food, oxygen, and beauty.
However, sometimes despite our best efforts, seeds sometimes just fail to germinate.
So, by doing this simple yet helpful germination test will give you a head start in your planting season. Make sure to take notes……this is one of the reasons that keeping a garden journal is so helpful.
Reasons Why Some Seeds Fail to Germinate
Understanding the various reasons behind seed non-germination is crucial for achieving a thriving plant growth.
Here are some of the main issues when seeds do not sprouting and what can be done about it.
Why seed germination is important.
Seed germination is an essential process in plant growth and is crucial for the survival of all plant species that populate by flowers and seeds.
Germination occurs when a seed begins it life cycle. The seed is planted and then if conditions are favorable, the tiny embryo inside the seed starts to develop into a new plant.
Without this process, no new plants would grow, leading to an eventual decline in crop yields.
One of these reasons that seeds fail to germinate is planting the seeds were planting either too deeply or too shallow for proper germination to occur. Make sure to read the back of all your seed packet as there is wealth of information there on planting depths, soil conditions and timing.
Another factor that can inhibit germination is poor soil; soil that lacks nutrients or has high acidity levels can negatively affect the growth of seeds.
Furthermore, temperature plays a critical role in seed germination as some species require specific temperatures to initiate their growth processes.
Lastly, excessive watering or insufficient watering can also lead to unsuccessful seed germination because it affects the moisture uptake by seeds which are essential during the early stages of development.
Understanding how seeds germinate, and identifying factors that may hinder successful growth will help gardeners and farmers achieve higher yields while conserving resources such as water and energy.

Low quality seeds may not germinate.
Low-quality seeds have less of a chance of sprouting and growing into healthy plants.
Some factors that contribute to low-quality seeds include improper storage conditions, age, genetic instability, and poor breeding practices.
It is essential for gardeners and farmers alike to invest in high-quality seed varieties from reputable sources that guarantee strong genetics and proper storage conditions for optimal germination rates.
Overall, investing in high-quality seeds is essential for successful gardening. Better seed quality helps insure a better harvest.
Improper Storage:
Proper storage equals a better germination outcome; make sure to keep your seeds out of the sunlight and heat.
seeds not sprouting due to storage issues?
Seeds stored in a damp or humid environment have a high chance of rotting rot before being able to sprout.
Another factor to consider when storing seeds is their age. Seeds have a shelf life, after which they become less viable for germination. It’s crucial to know the approximate lifespan of different types of seeds and use them before they exceed their expiry date.
Keeping your seeds in a sealed container helps prevent any dampness or bugs from getting inside. You can also add some desiccant packets into the container as these help absorb any excess moisture present in the air and keep your seeds dry.
By following these basic principles of seed storage, you reduce your risk or mold or any type of fungal disease plus you’ll increase your chances of successful germination rates and healthy plant growth.

Seeds that aren’t stored correctly can die:
The main reason why seeds do not sprout is improper storage. Seeds that are not stored incorrectly can lose their ability to germinate.
- most seeds need cool, dry conditions to stay viable
- seeds are exposed to moisture or high temperatures, may start to rot or mold
- seeds stored in an area that is too cold, may freeze and become damaged
- store seeds in an airtight container with a silica gel packet
In addition to proper storage conditions, it’s also vital to use fresh seeds. As time passes, the viability rate of seeds is likely to decrease if they are saved for an extended period.
Watering Problems:
Maintaining proper watering practices is extremely important when sprouting and growing seeds.
Overwatering can cause waterlogging, which reduces oxygen levels in the soil and suffocates plant roots. On the other hand, underwatering can also be detrimental to seed germination as it leads to inadequate soil surface moisture levels, hindering seed growth and development.
To avoid watering problems when trying to grow young plants from seeds, it’s important to find a balance by monitoring soil moisture levels regularly. One way to do this is by using a moisture meter or testing the soil with your finger- if it feels dry about an inch down then you should water your seeds.
By giving them just enough water at regular intervals, you’ll provide optimal conditions for successful seed germination process and healthy plant growth. For best results, the growing medium or soil must be loamy and have a good structure that has good water retention.
Proper Temperature for Seed Germination:
Soil temperature is very important; moist, warm soil helps encourage seeds to start growing. Typically, to successful sprout and grown most vegetable seeds, the temperature range between 65-75 F (18-24 C) should be optimal.
There are certain cool weather crops, like peas and snow peas, that think the ideal conditions are cool temperatures like in the spring when the garden soil can first be worked. Peas like moist soil but not wet soil.
However, some plants such as peppers may require warmer temperatures up to 85°F (29°C).
Cool season crops such as snow peas, lettuce, spinach, broccoli and kale like cooler temperatures between 45-65°F (7-18°C). Seeds can be damaged or killed completely by extreme temperatures, whether it’s too hot or too cold.
Cold, damp soil can cause seeds to rot. It should be emphasized that temperature plays a crucial role in seed survival.
To ensure successful germination, it’s essential to maintain a consistent temperature throughout the entire germination period. This can be achieved by keeping seed trays indoors in a warm room or using heating mats and grow lights if necessary.
By providing seeds with optimal growing conditions including proper temperature range, you can effectively increase your chances of success in growing healthy plants.
Lack of Light Affects Seeds Not Germinating:
The process of germination is crucial for the growth and development of plants. However, several factors can hinder or delay seed germination, including a lack of light.
Seeds require light to initiate photosynthesis, which is necessary for the production of energy. Without sufficient energy, seeds cannot break out from their protective covering and grow properly.
Moreover, some seeds require specific photoperiods to germinate successfully. Photoperiod is the duration of time that a plant requires darkness or light to stimulate its growth processes.
For example, some plants prefer short days while others need long days to develop correctly. Thus, a lack of proper light exposure can cause delayed or inhibited germination in such plants.
Lastly, low-light environments often have low temperatures that negatively impact seed germination rates due to limited photosynthesis and energy production capacity.
In such cases, it helps to provide additional lighting sources such as fluorescent bulbs or LED lights specially designed for indoor gardening purposes so that the seeds get enough illumination they need for successful sprouting and healthy plant growth.
