Soak tomato seeds in water for faster germination (2024)

Soak tomato seeds in water for faster germination? ›

The technique is proven by biological scientist. During the study the tomato seeds were soaked for 12, 24 and 36 hours, and the best results were achieved after a 24 hour soak. So if you have older seeds or you late with the sowings then you can just soak the tomato seeds in water for a day to speed up the germination.

Some seeds take a long time to germinate, and seed soaking can help to speed up the process. By soaking seeds in lukewarm water for 8-12 hours (some can go up to 24 hours, but never more than that), you help the seed to break dormancy and germinate faster.

Tomato seeds kept at warm room temperature and sprayed with water twice daily should sprout within a week. As soon as the seedlings break the surface, move them to bright light. A full-spectrum grow-light is ideal, but a sunny window will do provided the seedlings are watched closely to make sure they don't dry out.

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.

If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout. Question: Can the seeds that sink still be planted? Answer: Yes. Sow the seeds directly in the soil if it is the proper planting time or thoroughly dry seeds and plant when it is the appropriate time.

Warm temperatures (70-75 degrees F) help speed up seed germination; place your seed starting containers on a heat mat and cover with a humidity dome to get seeds started. Once seeds have germinated, shut off the heat mat and remove the humidity dome. seedlings grow best in cool room temperature, about 65 degrees F.

When starting seeds, the temperature indoors should be 70-80 degrees. The growing mix should be moist, but not wet, to aid germination. Seeds don't need light to germinate, although after germination, you should ideally give the seedlings 14 or more hours of light a day.

Soaking can accelerate germination and increase the proportion of seeds that successfully germinate. Seeds have evolved a protective coating around the embryo so the embryo can survive being dispersed by some means. The coating protects the seeds until they find themselves in a suitable place to grow into a new plant.

Which method germinated the seed the quickest? ›

Germinate seeds faster

The paper towel method creates prime conditions for seeds to germinate in less time. Depending on the type of seed, the controlled moisture and heat conditions within the bag can enable seeds to germinate in a few days. You'll have a home or garden filled with bright new leaves in no time!

Soaking seeds can certainly speed up germination, and encourage a batch of seeds to germinate at a more uniform pace. However, there's little evidence that soaking improves overall germination rates for most high-quality seeds.

Plant Your Tomato Seeds

Place 2 or 3 seeds in each container or cell, and use a seed starter mix such as Miracle-Gro® Seed Starting Potting Mix to encourage fast root growth. Fill your containers with the potting mix and then add water until it's the consistency of a wrung-out sponge.

When seeds are soaked in water, they begin to warm up and produce carbon dioxide. Seeds are dormant, or at least close to dormancy. When we provide them with warmth and moisture they start to grow.

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.

Water is considered the primary germination regulator, as germination begins with seed imbibition. Sufficient moisture must be present for germination to take place.

Take a paper towel and run it lightly under the tap. Make sure the paper towel is damp, but not soaking. If seeds get too wet, they may end up rotting before they're able to sprout.

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