Soaking Seeds Before Planting: Method That Worked Best for Us

Spread the Word!

There’s a lot of debate that revolves around whether seeds should be soaked before planting.

Many varieties of seeds do not need to be soaked before planting as they can absorb water from the soil. 

Soaking seeds before planting can speed up the germination process by introducing moisture into the seed, weakening its coating, and prompting the seedling to emerge. Seeds should be soaked between 12 hours and 4 days which can be done by either immersing them in a jar of water or covering them with a damp cloth.

Here’s my experience with soaking seeds and what I found that worked really well when preparing seeds for the upcoming planting season.

How to Soak Seed Before Planting

Soaking seeds before planting is a process that can be done in several ways.

The first method involves placing the seeds in a container of water for about 4 days. This will work with fully ripened-fruits and vegetables.

The good seeds will be at the bottom, dry them out on a washcloth and pack them away in a sandwich bag, and don’t forget to label them.

The second method is to place them on top of a dampened paper towel for more than 24 hours, remove them from the towel when there are signs of germination and root development and place them on top of potting soil in your desired container.

I use this Miracle-Gro Potting Mix from amazon, which ensures my plants stay healthy long after repotting. You can find it by clicking here.

This specially formulated blend of potting soil is designed to give your plants the perfect balance of nutrients, moisture, and aeration for vibrant plant growth.

The third method is to place them in cold water for about an hour, remove them from the water, and allow them to dry out. These methods are not mutually exclusive, so experiment with all three ways on your plantings this year.

Soaking the seed before planting is to make sure the seed is thoroughly hydrated. This process helps in preventing the seed from drying out and dying.

You can either soak the seeds in a cup of water for an hour or place them in a jar with water, cover them with a cloth, and leave them overnight. Alternatively, you can soak the seeds in boiling water for ten minutes.

Contrary to soaking seeds, we have also tried drying seeds out before planting, which works for certain types of seeds.

Why You Should Soak Some Seeds Before Planting

Seeds need water to sprout. You can’t just plant them in moist soil and hope for the best because there is a chance that they will dry out before they grow roots. Soaking them beforehand ensures they are ready to grow when you plant them.

It is vital to soak some seeds before planting. If you don’t, the seeds will take a long time to germinate or may not even germinate at all.

If you live in an area where it rains often, this shouldn’t be an issue because rainwater is enough for the seedlings’ needs.

If you live in an arid region and it doesn’t rain often, it’s essential to soak your seeds before planting to have enough moisture to survive until the next rainfall comes along.

Seeds need to be soaked in water for a few hours before planting. This helps them to absorb water and expand. However, some seeds, like onion and garlic, are best left to soak overnight.

After the soaking process, you can plant the seeds into the soil or a pot of soil mix.

However, this is only sometimes the case. Some seeds should not be soaked before planting because they are more likely to rot and die.

These seeds include tomato, pepper, and eggplant. Planting these seeds by just sprinkling them on the soil is best.

There are many good places to get seeds, but you just can’t beat this seed pack I got from Amazon. All seeds germinate quickly and grow into healthy, producing plants, and it’s very affordable.

What Seeds Should not be Soaked Before Planting

Types of Seeds to Soak before planting

Even though some plant seeds may need to be soaked in water, a few should not be soaked before planting.

Here are the seeds to avoid soaking before planting:

  • Seeds that need light to germinate, such as onion or lettuce.
  • Seeds with a hard outer coating, such as peas and beans.
  • Seeds need to be planted in the ground immediately.
  • Seeds with a hard outer shell, such as beans and peas. These need to be soaked in water to soften the outer shell, but they can still be planted without soaking.
  • Planting packets that contain a mix of different seeds. These packets should not be soaked before planting because they will not all require soaking.
  • Seeds that have been treated with pesticide or fungicide. Pesticides and fungicides protect plants from being attacked by insects or diseases; therefore, it is best to wait until after the seedlings appear so you can soak them for 20 minutes before planting them outdoors.

So, next time you soak the seeds, keep in mind this checklist and avoid soaking these seeds before planting.

I have had the best results with this seed starter kit from Amazon, which guaranteed the success of my seeds, whether they be vegetables, citrus, or flowers.

Do Soaked Seeds Burst Their Seed Coats

seed germination

The answer to this question is no; soaked seeds do not burst their seed coats. The seed coat protects the embryo from water or oxygen damage. The seed coat prevents the water from getting in, and it also prevents oxygen from getting in.

When seeds are soaked, they absorb water and grow. Therefore, soaked seeds are sometimes called “hydrated” seeds.

The seed coat is the outermost layer of the seed. It protects the embryo from damage and helps it to survive harsh weather, such as drought or frost. The seed coat is made of a tough material called “testa.”

The testa may burst if the seed absorbs too much water quickly or if it absorbs water at a temperature too high for its testa to withstand.

What Happens When Seeds are Soaked in Water Overnight?

This is a question that many people who are interested in gardening have asked. Seeds absorb the water and swell when they are soaked in water overnight. This allows the seed to grow.

Therefore, the answer to the question of what will happen when seeds are soaked in water overnight is that they will grow.

This is because the seeds absorb the water and swell, absorbing nutrients from the soil and air. Next, the seed’s cells divide and grow, eventually forming a root that sticks out of the seed’s bottom. This root absorbs nutrients from the soil, which help it grow into a plant.

When seeds are soaked in water for a long period, they can grow roots and eventually become plants.

The water the seeds are soaked in will start seeping through the seed’s hard outer shell and into its soft interior.

The water will dissolve and break down some of the natural chemicals (enzymes) found inside the seed. This process can help soften a seed, making it easier for it to germinate.

Pro Tips For Soaking Seeds Before Planting

Soaking seeds before planting is soaking them in water for a certain amount of time to help them germinate and become healthy seedlings. The process is simple, and you’ll reap the benefits of a healthy plant.

The following are some tips for soaking seeds before planting:

  • Soak your seeds in a container filled with water for about 12 hours.
  • Seeds need enough water to be fully submerged. So make sure you have enough water, and remember to add extra water if needed!
  • Ensure the container has enough room for your seedling roots to grow without cramps.
  • Keep the seeds at room temperature and away from direct sunlight or heat sources; this can cause them to dry out too quickly.
  • The water must be warm and hot enough. The temperature of the water should be between 60-70 degrees Fahrenheit.

Remember these best tips, plant your seed, and watch it grow!

The Takeaway

There are different opinions on whether seeds should be soaked before planting. While some believe the seeds don’t have to be soaked before planting because, ultimately, the seeds will absorb the water after it is planted, others believe it is of utmost necessity to soak the seeds before planting.

This is because it will help speed up the germination process and make the plant healthier and more robust.

However, one more important thing to understand is that not all seeds need to be soaked before planting.

Likewise, some seeds can be cleaned before planting. So, next time you plan to soak the seeds, check whether it requires soaking, and then go ahead with the entire process carefully!
