Throw your seeds into a small bowl or cup filled with warm water (just enough to cover the seeds). For thick-skinned seeds like peas, aim for 8 to 10 hours (or overnight, assuming you soak them right before bed and sow them first thing in the morning). For thin-skinned seeds like snap beans, soak for 2 to 4 hours.
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. Some seeds will naturally float, and some will stay below the surface.
Seeds absorb water when soaked. This makes them soft and big. Soaked seeds germinate faster. It is also easy to cook them.
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.
Too much soaking in water and a seed will drown. It is recommended that you only soak most seeds for 12 to 24 hours and no more than 48 hours. The seeds of some species of plants can survive longer soakings, but you should only do this if the specific instructions for this species recommend so.
Most of the seeds germinate best in dark environments. The presence of light tends to inhibit their growth. The light decomposes carbonic acid gas and expels oxygen which leads the seed to harden. These gases are key factors that promote germination.
Many seeds germinate much quicker in paper towels (versus seeds that are started in soil). The heat, moisture, and controlled conditions inside a plastic baggie help them germinate in only a few days (or less, depending on the seed).
The seeds you shouldn't soak include: carrots, lettuce, radish, celery, turnips, and spinach. Listen to Cathy Isom's This Land of Ours program here.
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.
Seeds need to be moderately moist to sprout. Seed germination is highly dependent on watering. Too dry and they won't get the message to sprout, too wet and they will rot in the dirt.
Not all seeds have the same light requirements. Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007).
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate.
Pre-Soaking.
This method could be the fastest way to germinate seeds. Place seeds in a shallow container in warm water and leave them for 16 to 24 hours (smaller for 16, bigger for 24). Remember not to expose seeds to temperatures higher than 80°F (26.6°C) and not to pre-soak seeds for more than 24 hours.
Will grass seed germinate on top of the soil? Yes; in fact, germination will suffer if too much soil is placed on top of the seeds. The experts at Jonathan Green recommend placing a thin layer of mulch or topsoil over them to help keep them moist and warm and promote growth.
One of the most popular ways to germinate seeds is the paper towel method.
The life cycle for Fast Plants is extremely short; under ideal growing conditions of continuous light, water and nutrition, plants will produce harvestable seeds approximately 40 days after planting. A day or two after planting and watering, the tiny seed germinates.
Some seeds like Allium 'Purple Sensation' and Eryngium giganteum need a long period of cold-moist stratification with alternating temperatures. These are the most difficult seeds to germinate.
While you can germinate certain seeds without soaking, your chances of success and the speed of germination can be greatly increased if you do. It can mean the difference between one or two seeds germinating or almost the whole batch when done correctly.
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.
You should observe seeds sprouting in about five to seven days. 6. The biggest drawback to the paper towel method is that the delicate, sprouted seeds must be transplanted manually to soil or another moisture-holding medium such as vermiculite. The main root is very delicate and should not be touched.
