What is the reason for soaking seeds before planting?

Author: Joe Marvin  |  Last update: Saturday, August 19, 2023

Soaking seeds supplies your plants a jump start right at the beginning of their lives. The water both softens the seed shell and supplies water to the seed interior. Once soaked, seeds and the plants inside them use that moisture to grow and push out new growth.

Is it necessary to soak seeds before planting?

By soaking the seed, it enables the new growth from the inside to push through the hard shell and grow. The seeds that could benefit from a good soaking include: corn, pumpkin, beans, chard, beets, and peas. The seeds you shouldn't soak include: carrots, lettuce, radish, celery, turnips, and spinach.

What happens if you don't soak seeds?

Although seeds can germinate without soaking, it does greatly increase germination rates (depending on the plant). If you want more reliable results, this extra step is well worth the effort.

How long should you soak seeds before planting?

Examples of seeds that benefit from soaking include peas, beets, cucumber, corn, squash, pumpkin and beans. In a bowl, cover your seeds with warm water and leave to soak for 6-24 hours. Smaller seeds and those with thinner coats need the shorter time, and larger seeds with thicker coats need the longer period.

What happens to a seed when it is soaked in water overnight?

Seeds absorb water when soaked. This makes them soft and big. Soaked seeds germinate faster. It is also easy to cook them.

How long can you let seeds soak in water?

Place the seeds in water and let the pre-soaking process continue for 8-24 hours depending on the seed size. Try to use filtered water instead of tap water if it's available, and don't let them soak for more than 24 hours. Immediately after the seed soaking period is over, the seeds need to be planted out.

What are the benefits of soaking seeds?

By soaking the seeds, you can quickly boost the moisture content around the seeds, which signals to the seed that it is now safe to grow. And lastly, for some types of seeds, they actually contain germination inhibitors that are designed to prevent a seed from germinating inside the fruit.

Should you rinse seeds after soaking?

Make sure to strain and rinse the nuts or seeds after soaking to eliminate the residual water which contains the absorbed enzyme inhibitors and toxic substances. Once you have given them a good rinse, enjoy them immediately or store them in your refrigerator for later.

Do good seeds float or sink in water?

One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.

How do you know when seeds are done soaking?

Just long enough for the seeds to swell but not so long that they might begin to sour and rot. Overnight is usually good. Many sources recommend 8-12 hours and no more than 24 hours. Again, too much soaking and the seeds will start to decompose.

How do you dry seeds after soaking?

Keep it covered with a light cloth to keep out dust and bugs. Or, you can also use an oven between 115 to 150 degrees Fahrenheit to dehydrate nuts and seeds after soaking. Keep the nuts and seeds in the oven for 12 to 24 hours, stirring occasionally, until completely dry.

Can you germinate seeds in just water?

Speed sprouting by presoaking seeds

I pour hot tap water into a shallow container, empty a packet of seeds into the water, spread them out, and let them stand for up to 24 hours. Soak the seeds for any longer and they might rot. The seeds swell as water penetrates the seed coat and the embryo inside begins to plump up.

Why do some seeds float on water while others sink?

Seeds may float because they lack viable embryos or nutrient stores, making them less dense than “good” seeds that sink in water. Or, they may float because they have air pockets inside, which don't always affect seed vigor or viability.

How old can seeds be and still germinate?

All seeds will be viable for one to two years. After two or three years, germination rates will drop for many types of seeds and will eventually fall to zero. So, stocking up on seeds for an “emergency” isn't a good idea because they don't last forever. Download a free chart that tells you if your seeds are too old.

How do you know if seeds are good or bad?

Take your seeds and put them in a container of water. Let them sit for about 15 minutes. If the seeds sink, they are most likely still viable. If they float, they probably will not sprout.

How do you germinate seeds with vinegar?

Soaking your seeds in DYC vinegar in most cases speeds up seed germination. The acid in the vinegar helps to break down the seeds outer coating and the vinegar also helps to stop any external pathogens from settling on the seed. Mix 1 teaspoon of DYC vinegar into one cup of water.

Why add salt when soaking nuts?

Basically, you soak the nuts in salt water (salt is necessary to help neutralize the enzymes) and then you dry them. Be sure to fully dry your nuts or they could become moldy. You do not want to dry your nuts any higher than 150°F.

Why do you soak nuts overnight?

Benefits of soaking nuts

"Essential nutrients like iron, protein, calcium, and zinc are better absorbed by the body when you soak the nuts. The water removes the phytic acid present in acids which causes indigestion. So, soaking nuts helps in digesting them properly and reaping the benefits of these nutrients.

What should seeds be soaked with right?

Soaking is beneficial in two ways; it can soften a hard seed coat and also leach out any chemical inhibitors in the seed which may prevent germination. Anything from 1-3 hours in water which starts off hand hot is usually sufficient. If soaking for longer the water should be changed daily.

How many seeds do I plant in one hole?

Like most things in gardening, there are always exceptions to this rule of 2-3 seeds per hole. If you're planting large seeds like cucumbers, melons, or pumpkins, you should only use one seed per hole. However, you can still plant seeds close together and then thin them out once they've established themselves.
