If your Nadeau African violet miniature seeds are not germinating, the problem is usually related to the growing mix, moisture, light, temperature, or sowing method. I am Ronn Nadeau, and I have been producing and selling African violet seeds since 1980. Over the years, I have tested different growing conditions to understand what helps African violet seeds germinate more reliably.
The first things I would check are moisture, growing mix, light, temperature, and how the seeds were placed. African violet seeds are extremely small, so small changes in their growing environment can matter.
On my own instructions page, I recommend using a peat moss based germination mix, keeping the mix moist, placing the seeds on the surface, and covering the container with a transparent bag. I also recommend good artificial light with the sowing surface about 9 to 12 inches below the light.
Yes. The growing mix can have a major effect on African violet seed germination.
In one of my germination experiments, I tested 10 commercially available mixes. The results were quite different even though several of the mixes looked very similar. Two mixes produced much better results than several others. One had an average germination rate of 43% after 24 days, while another reached 39%. Some of the other mixes were much lower.
That is one reason I recommend starting with a peat moss based germination mix rather than using ordinary garden soil. If you already have a different mix, you can test a small number of seeds in it instead of using your entire packet.
The growing medium needs enough moisture for the seeds to sprout, but it should not stay soaked. When I prepare the mix, I moisten it with tap water or reverse osmosis water. If the mixture becomes too wet, I add some dry mix to correct it. I then place about one inch of the moist mix into a small container.
A covered container helps keep the moisture from disappearing. If there is no condensation inside the transparent cover after a day or two, the starting mix may not have been moist enough.
African violet seeds should not be buried under the growing mix. The seeds are very small, so I place them on the surface. I use a sheet of paper and gently tap the seeds onto the surface so they spread out instead of landing in one pile. If you have covered your seeds with a noticeable layer of soil or mix, that could be one reason they are not appearing.
Follow these simple steps:
This approach creates a suitable surface for the small seeds to start developing.
Good light is important for African violet seedlings. I recommend a white LED or fluorescent light rather than relying on weak window light.
On my growing instructions, I recommend keeping the sowing surface about 9 to 12 inches below the light and using a 12-hours-on, 12-hours-off schedule.
University of Minnesota Extension also notes that fluorescent and LED lights can be used for African violets and indoor plants. A dark corner of the room may not provide the consistent light that young seedlings need.
Temperature can affect early African violet growth. I recommend avoiding temperatures above 85°F during germination and the first several weeks after the seedlings appear.
In my research, I observed that tiny African violet seedlings did not grow well at temperatures higher than 85°F during this early period. Once the young plants grow stronger, they can handle warmer conditions better. This is especially important if you are growing seeds in a warm room, greenhouse, or during a hot summer.
You may see tiny African violet sprouts at around 14 days, but this is not a strict deadline. My instructions state that sprouts generally begin appearing around 14 days, plus or minus a few days depending on light and temperature. Poor growing conditions can make the process take longer. So, do not throw away the container simply because you do not see seedlings after exactly two weeks.
Uneven germination does not always mean something is wrong with the entire packet. African violet seeds can have different germination rates. In my research, even fresh African violet seeds did not consistently approach 70% germination, and one older batch used in testing had a best observed rate of about 50%. I account for expected germination when determining the number of seeds included in packets.
This is also why I recommend giving the remaining seeds time instead of assuming that every seed should sprout at exactly the same time.
If your seeds have not germinated, check these conditions before starting over:
| What to Check | What I Recommend |
| Growing mix | Use a peat moss based germination mix |
| Moisture | Keep the mix moist, not soaking wet |
| Seed placement | Keep seeds on the surface |
| Cover | Use a transparent bag or cover |
| Light | Use white LED or fluorescent light |
| Light distance | About 9 to 12 inches above the surface |
| Light schedule | 12 hours on and 12 hours off |
| Temperature | Keep early growth below 85°F |
| Time | Allow more than 14 days if conditions are not ideal |
These points come directly from my growing instructions and germination research.
Once seedlings appear, continue keeping their environment stable. I recommend leaving them covered until they become large enough to transplant.
My instructions explain that seedlings may reach about 1/4 to 1/2 inch after several more weeks, although poor conditions can make this take longer. At that point, they can be moved into small pots.
I also recommend labeling the seedlings because plants grown from seed are genetically different from one another. This makes it easier to keep track of individual plants as they develop.
Yes. You do not need a greenhouse or complicated equipment to start African violets from seed. A suitable germination mix, consistent moisture, good artificial light, and a stable temperature can provide a practical home setup.
African violets also grow well indoors under suitable light and temperature conditions, according to University of Minnesota Extension.
If you are ready to try again, take a close look at your growing mix, moisture, light, temperature, and sowing method before assuming the seeds are the problem. I have spent many years testing African violet seed growing conditions, and my goal is to give growers clear instructions that make the process easier to understand.
At Nadeau African Violet Seeds, I offer rare African violet seeds for growers who want to grow unique plants from seed. You can also follow my detailed sowing instructions when you begin your next batch.
Tiny sprouts often begin appearing around 14 days, but the exact timing can vary with temperature and light. Some seeds may take longer, so patience is important.
No. I recommend placing the seeds on the surface of the germination mix rather than burying them.
I recommend white LED or fluorescent light, with the sowing surface about 9 to 12 inches below the light and a 12-hours-on, 12-hours-off schedule.
Not every mix performs the same way. My research found significant differences among 10 commercial germination mixes, so I recommend using a suitable peat moss based mix and testing an unfamiliar mix with a small portion of seeds first.
Yes. I recommend keeping temperatures no higher than 85°F during germination and the first several weeks of seedling growth.
Yes. Growing African violets from seed is well suited to indoor growing when you can provide steady moisture, suitable light, and a stable temperature.
