How Long Should You Soak Seeds Before Planting?


Have you ever wondered how long you should soak seeds before planting? Soaking seeds can help speed up the germination process and increase the chances of successful planting. However, not all seeds require soaking, and different seeds require different soaking times. In this article, we will answer the question, "How long should you soak seeds before planting?" and provide you with some useful tips and information.


The answer to the question of how long you should soak seeds before planting varies depending on the type of seed you are planting. Here are some general guidelines:

  • Small seeds like lettuce, spinach, and carrots should be soaked for about 12 hours.
  • Medium-sized seeds like beans, peas, and corn should be soaked for 24 hours.
  • Large seeds like pumpkin, squash, and watermelon should be soaked for 48 hours.

It’s important to note that not all seeds require soaking. Some seeds, like those of the tomato and pepper plants, don’t need to be soaked at all.

Things To Know

Here are some things to keep in mind when soaking seeds:

  • Use room temperature water for soaking.
  • Don’t soak seeds for too long, as this can cause them to rot.
  • After soaking, rinse the seeds thoroughly with fresh water before planting.
  • Some seeds like sunflowers and lupines have hard outer shells that need to be scarified (scratched or nicked) before soaking to help with germination.


Here are some tips to help ensure successful seed soaking and planting:

  • Use a bowl or jar that is large enough to allow the seeds to soak and expand without crowding.
  • Cover the seeds with a few inches of water to prevent them from drying out.
  • Label each jar or bowl with the type of seed and the date it was soaked.
  • Keep the soaking seeds out of direct sunlight and in a warm, but not hot, location.
