You may have heard that it’s important to soak seeds before planting. This process works for many plants, but does it work for peanuts?

You should soak peanuts before planting because it speeds up the germination process. It’s best to soak the seeds in warm water for 12 to 24 hours, ideally overnight. Once you remove the seeds from the water, get ready to plant them right away. You should notice rapid plant growth this way.

The rest of this article will discuss soaking peanuts before planting in greater detail. So if you want to grow peanuts and looking for helpful information on germination, be sure to read on.

Why Should I Soak Peanuts Before Planting?

You should soak peanuts before planting because water gives the peanut seeds the metabolic functions needed for germination. That way, when you plant the peanuts, germination will occur rapidly. 

When seeds absorb water, it triggers a metabolic function. It gives the plant the energy to get ready for germination, so it’s great if you want to grow your peanuts as quickly as possible.

Peanut seeds need moisture to germinate. Putting them in water makes them think they’re in the ground already. So once you plant them, they’re instantly ready for germination. 

You can think of it like this: You’re tricking the peanuts into thinking they’re somewhere they’re not.

Soaking Peanuts Before Planting: The Process

Now that you know it’s a good idea to soak your peanuts before planting, I want to discuss how to do it. Thankfully, it’s a low-effort task.

Below are some helpful tips on soaking peanuts before planting.

Use Warm Water

The first thing to note is the importance of using warm water. When it comes to peanuts, the soil temperature needs to be above 68°F (20°C). So as you can imagine, it’s best to use water that’s also above 68°F (20°C).

You want the peanuts to think they’re in the ground, so using water of a warm temperature will help with that. That’s why cold water is a big no-no. Peanut plants don’t grow well in cold conditions, so you certainly shouldn’t use cold water to soak them!

Don’t Soak Your Peanut Seeds for More Than 24 Hours

The amount of time you leave the peanuts soaking is significant. Leaving them soaking for too long can damage the seeds, making them useless.

For peanuts, it’s best to soak them overnight. You don’t need to soak them for more than 12 hours, but you can if you want to. Just don’t go over 24 hours, as the seeds may drown at that point.

Plant the Peanut Seeds Right Away

After the peanuts have soaked for a few hours, you’ll want to plant them as soon as possible. If you don’t plant them right away, they’ll dry up. This may stop them from germinating, which you certainly don’t want.

Make sure the soil is prepared so that you can place the seeds directly from the water into the ground.

Is Soaking Peanuts Before Planting Necessary?

Soaking peanuts before planting isn’t necessary. However, it’s a good idea if you want to promote faster germination and growth. So if you have the time to do it, you should. But it won’t affect the end product if you don’t.

Plants have germinated and survived for thousands of years without the help of humans soaking the seeds in water. So your peanut plant will certainly survive without the help of a soak.

So although it’s not necessary, it’s a good idea. 

And it’s not just peanuts that benefit from being soaked before planting; there are many other types of seeds that benefit from it. Some of them include beans, cucumbers, peas, and pumpkins.

Other Ways To Promote Germination

Although soaking is one of the best ways to promote seed germination, there are other things you can do. The most critical factors for germination are water, oxygen, temperature, and light.

Of those factors, water is the most important for germination. However, it’s still important to pay attention to oxygen and temperature.

With that in mind, let’s look at other ways to promote germination in peanut seeds.

Avoid Overcrowding the Seeds

If you plant your peanut seeds too close together, they won’t be able to germinate and grow very much. Overcrowded seedlings won’t have enough access to oxygen and water, which are essential for germination.

Another issue that can arise from overcrowding is too much CO2 in the area. If your seeds are too close together, they will release CO2. This CO2 will then get trapped because of the lack of space, and the peanut plants may die.

Try to plant your peanuts approximately six inches apart to avoid these issues.

Water Your Peanut Seeds Once a Week

I’ve already discussed the importance of soaking peanuts in water before planting. However, it’s also important to continue watering them once they’re sown in the soil. 

Watering them after planting will give them more of what they need to germinate, so this is an important step.

Once you’ve planted your peanuts, it’s good to water them right away. Then, you should generally water them once a week or whenever the soil looks and feels dry.

Ensure the Soil Is at the Right Temperature

If the soil isn’t at the right temperature, the germination process may not go as planned. The best germination temperature depends on the type of seed you’re planting. For peanuts, it’s approximately 65°F (18.33°C).

But it’s not just cold temperatures that can inhibit germination. If the seeds dry out or drown, germination is unlikely to occur.


You should soak peanuts before planting because it promotes germination and can give your peanuts a good head start in the growing process. It takes around 12 hours of soaking, so it’s easy to do.

However, it’s important not to drown the seeds. Try not to leave them for more than 24 hours. If they stay in the water for too long, they could get permanently damaged. Additionally, be sure to use warm water because cold water won’t help with germination.
Other essential tips for germination include avoiding overcrowding and keeping the soil at 65°F (18.33°C) during germination.
