What determines the germination of seeds
Germination of tomato seeds depends on many factors, but, for the most part, it all depends on the person. Of course, you should never discount the fact that grains or soil can be of poor quality. Then no manipulations will help the seeds to sprout faster.
IMPORTANT! On average, tomato grains germinate within 5-7 days. This period increases or decreases, depending on a number of factors.
Among the main factors, ceteris paribus, affecting the rate of germination of tomato grains, the following can be noted:
- Preplant treatment of seed material;
- Variety of tomatoes;
- Air temperature;
- Air humidity;
- The quality of the seed.
How many raw tomato seeds sprout
If you picked up tomato seeds yourself, took it from neighbors or sow cheap purchased seeds, then you will have to wait 1.5 to 2 weeks for seedlings.
The fact is that tomato grains are covered with a sufficiently dense and rigid outer shell, so that sprouts appear, this shell needs to be punched. In addition, the composition of the grain includes special essential oils that inhibit the biting of the sprouts. This is a natural containment mechanism.
ON A NOTE. Of course, even untreated seeds can sprout earlier. But it is, rather, luck and coincidence.
How many treated seeds germinate
Seed processing can be of two types:
- Factory. When all the necessary procedures for preparing for sowing are carried out by the manufacturer;
- Home. When a summer resident prepares for planting grain. Typically, the procedure takes place in the form of soaking in a solution of the active substance.
Moreover, if the seed material has been processed at the plant, then an additional soaking procedure is not necessary.
Properly prepared planting material will give the first seedlings 5-7 days after sowing. And “fresh” and strong grains can germinate already on the 4th day.
NOTE! Data for seeds of the same quality are given. It may well happen that unprocessed "fresh" seeds will sprout faster than processed ones, but they have lain in your box for several years.
How differs germination depending on the variety
Another factor that can affect the timing of the first tomato shoots is the variety. There are three large groups of tomatoes depending on the fruiting period - early ripening (early), mid-ripening, late ripening (late).
These varieties differ not only in the rate of appearance and ripening of the fruits, but also in the rate of the main biological processes inside the plants. Late tomatoes develop a little slower. And this applies, including, the period of emergence of sprouts.
Of course, with a full pre-sowing preparation, the germination period of late varieties can be accelerated, but under equal conditions they will sprout a couple of days later.
BTW. That is why different varieties are advised to sow in different containers, so that the seedlings appear at the same time, and it was possible to carry out all the procedures with all plants at once, and not select one copy.
Read about the best varieties of tomatoes in our article "Varieties of tomatoes."
How temperature affects tomato seed similarity
Plants love heat. And tomatoes are no exception. In order for the seeds planted in the ground to grow, they need to provide a sufficiently high temperature.
The less degrees the thermometer shows, the slower the germination of the grains. The same goes for temperature differences. They adversely affect the speed of emergence of seedlings.
In an ordinary apartment with central heating, it is quite problematic to regulate the desired temperature level.
But, if you have such an opportunity, then provide crops with a temperature of 25 degrees. This is the optimal mode for the fastest germination of tomato grains. And the greatest effect will be if you create a greenhouse effect for crops. It is very simple to do this, you just need to cover the container with the planted grains with cling film or a plastic bag.
ON A NOTE. In an ordinary apartment, the best place for sowing tomatoes not yet sprouted is under the battery. But you must not forget to maintain the necessary level of humidity in the greenhouse.
How does light affect germination?
In general, tomatoes are considered dark-like plants. That is, light is not a decisive factor for their germination. Moreover, it is usually advised to put a container of seeded tomatoes in a dark place.
ON A NOTE. But overall, seeds love light more than shade. Consider this fact when growing seedlings.
How does the quality of the seed
In fact, the quality of the seed is a decisive factor. If the grains that you are going to plant are expired or of poor quality, then none of your actions will help them to ascend faster. On the other hand, healthy and genetically strong grains will sprout even under the most adverse conditions.
Unfortunately, the quality of purchased seeds cannot be guaranteed. There is always a chance to buy dummies, "sleeping" grains, etc. But a number of simple rules will help minimize the chance of buying low-quality seeds:
- Buy only proven seed from trusted manufacturers. So there is less chance to run into counterfeit products.
- Do not store seeds in the refrigerator. So you just hibernate them.
- Do not buy expired seeds. Duration of storage of seeds - 5 years. In rare cases, there are varieties that can retain their properties for up to one and a half decades, but this is usually written on the packaging. If there are no such notes, then the variety is standard with a standard shelf life.
ON A NOTE. That is why do not try to buy seeds for the future. Take as many packs as you can sow. Every year, the germination of the material is getting worse and worse. In addition, new varieties and hybrids with improved characteristics appear every year.
Seedlings grown from high-quality seed material better tolerate picking and transplanting and give the best harvest.
How to speed up germination?
Despite the fact that, by and large, the germination of tomato seeds is due to the characteristics of the variety and external factors, summer residents are skilled at influencing the speed of seed germination.
To do this, they use several procedures, the essence of which is the impact in a certain way (drug or physical process) on the seeds.
Is it necessary to stratify tomato seeds
In general, tomatoes do not need stratification. It is enough to soak. But, if you still decide to carry out this procedure, then use the cold stratification method.
What is bubbling, or why seeds of a tomato aquarium compressor
Bubbling is a way to “wake up” the seeds and process them before planting. For the procedure, you will need an aquarium compressor that will saturate the water with the seeds in the air. As a result, the outer shell will soften.
The disadvantage of the method, in addition to the need for a compressor, is its duration. Sparging should be carried out at intervals of 16 hours.
How to soak tomatoes?
Soaking tomatoes is very simple. You will need a shallow container, gauze (cotton pads) and a solution for soaking. Seeds are placed inside the gauze "envelope" and soaked in a solution of the active drug. After which the grain is left for a day, every 4 hours moisturizing a rag.
After 24 hours, the seeds are washed, dried and planted.
More information about seed soaking is presented in our article, “Soaking Seeds Before Planting, How to Soak Properly.”
How to choose only high-quality tomato seeds and reject bad material?
The easiest method is to sort using saline.
- Pour a teaspoon of salt without a cup into a cup of water and mix thoroughly.
- Pour the seeds into a cup and wait 10 minutes.
- Surfaced grain can be sent with a clear conscience to the bin. But those that sank to the bottom should be washed and sent to the soaking procedure.
How does shelf life affect germination?
As already mentioned, every year the seeds go into hibernation deeper and more difficult to germinate. It is much more efficient to use seeds purchased immediately before planting.
What is dragee
Dragee coating is a coating of grains with a special nutrient mixture to accelerate the germination, disinfection and stimulation of seedling growth.
The composition of the nutrient mixture includes peat, mineral components, humus, fungicides and an adhesive that attaches all this mass to the seed.
Seed pelleted mainly in factories, although experienced summer residents carry out the procedure at home.
IMPORTANT! Coated seeds do not need to be soaked!
Seed treatment before sowing
Important clarification. Seed material must be processed immediately before sowing. This means that you must land immediately after the soaking procedure (sparging, stratification, disinfection, etc.).
The only thing is to dry the seeds before sowing. But this will take no more than half an hour. That is, you need to plan all the procedures in such a way that, having finished one, you immediately began to conduct another. No need to leave the seeds lying half a day to no avail.
At what depth should tomato seeds be planted?
Depth of planting can adjust the sprouting period.
There is no need to plant tomato seeds too deep. On average, 1.5 cm will be enough. But very small grains can generally only be lightly sprinkled with earth mixed with sifted sand.
REFERENCE. Equally important is the quality of the soil. Buy light and nutritious soil for tomato seedlings or use peat tablets. On heavy soils, seeds germinate worse. “Undiluted” garden soil for germination is not recommended.
Why seeds did not germinate, common causes?
Sometimes it happens that in the expected time sprouts still do not appear. This phenomenon has 5 main reasons:
- Poor seed.
- Incorrect storage of seeds (too low or, conversely, too high temperatures).
- Incorrectly selected soil (too heavy ground).
- Presowing not done.
- Errors in planting (too deep) and in the care of seedlings (low temperature, low humidity).
What to do if the seeds do not sprout?
First, check seed temperature and soil moisture.
If all is well, then wait another 2-3 days. Perhaps you have planted too deep, and the seeds have not yet broken through the thickness of the earth.
If all the deadlines are long gone, and there are still no sprouts, you will have to reseed.
How to plant seeds
Tomatoes should be sown in light nutrient soil. Capacity for landing should be provided with a drainage system.
Seeds are placed at a distance of several centimeters from each other. Planting deep is not necessary. Enough holes with a depth of 1.5 cm are enough. After sowing, you need to carefully irrigate, cover the container with polyethylene or glass and put in a warm place until emergence.

How to choose a suitable landing time
Tomatoes need to be planted on the growing moon. This time is considered the most successful for the procedure. Planting on a dying moon is not advised, but, in extreme cases, you can sow these days. But in the full moon and new moon you can’t sow tomatoes.

Features of sowing in open ground
Sowing directly to open ground is not much different from sowing for seedlings. But there are still some nuances:
Firstlyneed to prepare the ground. In early spring, the earth is fertilized with organic matter. And you need to do this almost immediately after the snow melts. Also, do not forget about loosening the soil.
Secondly, immediately before planting, the soil must be decontaminated. It is best to use a solution based on Fitosporin-M.
ThirdlyThe landing is carried out in the second half of May. It’s pointless to plant seeds earlier, they still will not sprout before the soil warms up.
Fourth, after the emergence of seedlings until the fruit sets, seedlings need to be covered with spanbond or halves of plastic bottles at night.
ON A NOTE. When sowing tomatoes immediately into the soil for germination, it is necessary to lay a slightly longer period than usual.
Frequently Asked Questions
Do I need to soak the seeds before planting?
No, but this procedure will positively affect the time of emergence of seedlings. Soaked pelletized seeds are generally contraindicated! The liquid will destroy the entire layer with which such grains are coated.
Can I use old seeds?
Try, but be sure to soak them in a solution of hydrogen peroxide and follow the technology of planting and caring for the crops.
How many shoots will appear?
Properly sown tomato seeds germinate on the 5-7th day, plus or minus a couple of days.
How to plant seeds deeply?
Do not bury the seeds too much. 1.5 cm - optimal depth.
What to do with dragee seeds?
Just plant them for seedlings. This material has already been pre-sowed.
Sprouts appeared, what to do?
Rearrange the seedlings in a slightly cooler but brighter place for 3-4 days until all seedlings appear. Then containers with seedlings can be put on a permanent place.
Tomato seeds germinate about a week after planting. This process can either be accelerated or slowed down. Presowing preparation, following the lunar calendar and observing growing conditions significantly affect not only the speed of emergence of the first sprouts from the soil, but also the further development of seedlings.
