A Guide On Soaking Green Beans Before Planting

Last Updated on October 28, 2022 by Cinthia

Soaking green beans before planting is possible and makes them fasten the germination process that is sometimes derailed by external factors.

Why pay more for green beans when you can grow your own. It is one of the easiest ways to save money if you have a garden. If you saved some seed from last year’s harvest, you don’t need to buy new seeds as you can use the same ones to plant a new crop.

One of the easiest ways to guarantee germination for your green beans is to germinate them in water. When kept moist for several days, the outer shell cracks open and began to sprout without having to push through any soil or planting matter in the process.

Soaking seeds in water increases your germination rate and reduces potential diseases that prevent the seeds from proper germination.

Which Seeds Are Appropriate For Soaking

Seeds with hard coats are the best for soaking. They include beans, peas, pumpkins, squash, corn, etc. Smaller seeds like carrots, lettuce, radishes, and the like are hard to soak and don’t need it at all.

But do you know you can soak your flower seeds before sowing -sunflower, sweetpea, lupine, nasturtium take soaking so well.

Which Seeds Are Appropriate For Soaking

How To Soak Green Beans Seeds Before Planting

This is an easy process. However, the three ways you can do it

  1. Option 1. Put the seeds in a shallow bowl and cover them with water. Leave them for several days, observing them daily until you see them sprouting. Once they are fully sprouted they are all ready for planting.
  2. Option 2. Soak in an acidic environment by adding a tablespoon of coffee or a few drops of kitchen vinegar. The idea is to create conditions where are the seeds first get warm and dump to germinate. The acidic environment creates the warmth that the seeds need to germinate quickly.
  3. Option 3. Use a wet paper towel or napkin for germinating your green bean seeds. Wet your paper towel with water but don’t make it too wet to the draining point. Lay the paper towel on a clean surface spread a single layer of seeds leaving enough room between them and around the edges. Fold the other half of the towel over or lay another towel on top of the seeds. Secure the borders to ensure no seed falls out and set them aside. Place the wrapped seeds into a Ziploc bag or a jar and tightly shut them to hold in moisture and keep them in a warm area out of direct sunlight. Check for sprouting after five days by opening the paper towels likely and peeking in without unwrapping all of the seeds. If they haven’t germinated yet, reseal the bag and leave them for a few more days.

How Long To Soak Bean Seeds Before Planting?

Soak your seeds long enough for them to swell but not too long that they begin to turn sour and rot. Overnight is a reasonable amount of time, although many sources recommend 8 to 12 hours and no more than 24 hours.

Too much soaking will cause the seeds to start decomposing. If you use boiling water, the soaking time decreases. Most people swear by using warm water and soaking at bedtime and removing them first thing in the morning. Hard seeds like beans benefit from scarification before soaking, but be careful not to puncture the seed completely.

Other Considerations When Soaking Green Beans Before Planting

Don’t soak your seeds the night before rain is expected but wait until the forecast promises a good planting season. This helps you be able to get into the garden and not compact the soil too much. You don’t want to hold onto seeds you already germinated; instead, you want to immediately get them in the ground.

Remember, just because you soaked your seeds doesn’t mean you will not need to water them as soon as you plant them. Your seeds will only hold the right amount of moisture around the seed, not around the soil. They will need more water around the soil to necessitate their growth.

For those who use damp paper towels for germinating the seeds be delicate with the seeds when moving them to the garden or the pot to avoid breaking the stem or root. Don’t worry if the shoot is on its side; gravity will help it find its way down or up.

Saving Green Bean Seeds

So to be able to plant your seeds, you will need to have saved them from the previous harvest. Saving green bean seeds is easy; all you have to do is follow a few steps.

Choose The Best Green Beans

Select a few healthy plants you would want to save the seeds from until the final harvest. Select the first plants to produce mature beans, tall and robust with dark green leaves with a high number of pods.

Mark The Seed Grown Plants And Wait

To ensure you don’t destroy your harvest early, you can make them by tying something around them. Let the pods grow to maturity before you harvest them.

Pick The Dried Out Pods

Wait until the pods turn completely brown before you harvest them.  There should be no green on them at all. You will know the seeds are ripe when you shake the pods and hear the rattle of beans moving around inside. Squeeze the pods, and they should be crunchy to the touch, then you know they are ready to pick.

Remove The Seeds From The Pods

Once you harvest the dry beans, remove them from the pods safely without damaging the seeds.  Examine every seed, saving only the perfect ones. Throw away any seed eaten by insects wrinkled or has a different color from the rest of them.

Place the seeds on a paper towel to air dry for several days and final store them in a clean, dry container that is labeled waiting for the next season to plant them.

Do green beans need to be soaked before planting?

Green beans are one of the easiest vegetables to grow, but they do have a few quirks. They require a long growing season, but if you have a greenhouse, or can plant them early in your garden, they will produce well.

Yes. Green beans must be soaked in a solution of water and potassium nitrate for at least 6 hours, up to 24 hours. Potassium nitrate is available at your local garden center. This step will help the bean seeds to germinate more quickly, as well as make them more resistant to disease. 

If the instructions say to soak them for 24 hours, then they are probably just referring to an old-fashioned method of planting.

Newer methods call for rinsing the beans to get rid of any excess dirt and sand, and then planting them right away. I don't think soaking for 24 hours is necessary. If you soak beans in a solution of water and salt, it helps prevent bean disease. There are two diseases that can affect beans. The most common is Fusarium wilt, which occurs when the soil is too wet and cool and the roots have no air circulation. Soaking the beans in a solution of water and salt is supposed to kill off any spores that might be on the beans when they are planted. The other type of bean disease is Phythophthora root rot. This occurs when the soil is too dry and hot, with no air circulation. Soaking beans in a solution of water and salt also kills off any spores that might be on the beans when they are planted.

How do you soak green beans?

Soaking beans is very easy. Just place the seeds in a bowl and cover them with water. Let the seeds soak for at least 8 hours or up to 12 hours depending on your beans. After they are soaked, drain the seeds and place them in a mesh bag (or paper towel) in a warm place where they will germinate. You want the temperature to be around 80 degrees Fahrenheit. The ideal temperature for germination is between 70-80 degrees.

The seeds need light but not direct sunlight. If you put the seeds in direct sunlight, they may get scorched. Keep the seeds out of the fridge or freezer because this can stop the germination process.

How do you dry green bean seeds for planting?

Depends on how much seed and the climate you live in. It is not necessary to dry them completely. They will germinate more easily if they are moist, but not soaking wet. If your seeds are damp or wet, you can place them on a cookie sheet and put it in an oven on the lowest setting, about 200 degrees F for an hour or two. This will dry them out just enough so they will sprout.

Final Thoughts

Besides soaking green beans before planting, you can also save yourself some good-quality seeds from your green beans. Don’t shy away from keeping your seeds, especially if you notice there’s variety your growing is excellent.
