What Is The Average Time For The Seeds To Sprout ?

This article uncovers the average time for every type of seed to sprout, what you should know more about germination and the factors that affect the germination process.

Do you know when your seeds will sprout?

One of the most exciting phases of growing plants is to see the very first sprout in your seeds. Fascinating, isn’t it? It just only shows that, perhaps, you have done the right process of growing your plants. However, there might be times where the germination of the seeds don’t take place all at once – some have already started sprouting while the others haven’t yet. Could there be anything wrong with the process?


Don’t skip a heartbeat yet. Well, I, too, got worried about it when I started growing a variety of vegetables in my yard. But, it is definitely normal if that ever occurred in your mind. Something might have gone wrong with the process or maybe, you just need to do more research about the germination of your seeds.

What You Should Know about Germination ?

When the sprouting of a seedling becomes visible, grows and develops, that process is called germination. However, the outcome of this process is not constant for all types of seeds, such as angiosperms (flowering plants) or gymnosperms (seed-producing plants). The germination of the seeds alters under different environmental conditions. Insufficient or irregular provision of the prime necessities of the seeds such as water and oxygen can also delay the process.

At this point, you may expect that some of the seeds may not sprout on the day you expect them to. There could be just a delay with the process or they might not germinate at all.

Here are the major factors that can affect the days of development of your seeds.

  • Temperature
  • It can refer to air or soil temperature. When the temperature changes, the days of the germination could also alter. Every type of seed has its designated level of temperature it depends on.

    There are a lot of seeds that usually germinate between the temperatures of 16 to 24-degree Celsius. Some can take colder than that or even up to a freezing temperature. When it comes to the soil temperature, some seeds respond to -2 to -4-degree Celsius or when the soil is warm at 24 to 32-degree Celsius.

    The changes in the temperature enormously affect the sprouting of the seeds. We cannot alter the way the temperature goes but there is definitely something that we could do. We can route to different procedures – scarification and stratification.

  • Water
  • Water is absolutely vital to the germination process. When the seeds mature, they often get dry thus need more water to moisten them. That is why every seed should be supplied with enough water to prevent dormancy. It helps the seed grow, develop and break down all the nutrients it needs.

  • Oxygen
  • If oxygen is a significant factor for all the human beings, it is for seeds as well. The precise intake of the seeds of oxygen depends on how deep it is planted within the soil or what type of seeds you are planting.

    Some seeds delay the germination process or would not germinate at all when they are planted too deeply within the soil. It suffocates the seeds.

    On the other hand, some seeds have special type of coats which are seemingly locked and sealed. This do not let the oxygen get in which results to dormancy or delay in sprouting.

  • Exposure to Light or Darkness
  • Another factor that affects the development of the seeds is the exposure to light or darkness. Some seeds do not actually respond to this, but others have shown impressive progress to their growth.

  • ​Type of Crop
  • There are tons of variations of crops so if you’ve decided to grow your own, you should know that every type of crop has its own germination date. However, as what was mentioned before, the days it takes before they sprout can still alter under environmental conditions.

    So, what type of crop are you planning to grow? Do you want to when these seeds sprout? Take a look at the chart below

    NOTE: The average number of days listed in the chart is according to the optimal air temperature. Remember, the results may still vary when any changes in the environmental condition occur.


How long does it really take for the seeds to sprout? There’s no certain figure. The number of days always depends on what type of seeds or crop you’re planning to grow, what kind of environmental condition there is, and how you provide the vital nutrients your seeds need.

So if you haven’t seen one sprout yet, fret not! Chill and wait for some time until they are ready. You just need to supply what these seeds need and keep on providing the proper care.

What if you’ve got seeds but still not yet prepared to grow them? Save the seeds! But, how? Do you know how to properly store them? If you still don’t know what to do, this article will help you.
