Do tomato seeds need to be soaked before planting?
Simply soak seeds in warm water the night before you’ll be planting them to soften the hull of the seeds and help the sprout break the seal. Tomato seeds do not usually need to be presoaked, but if you’ve had particular trouble with germination, it’s worth a try.
Should all seeds be soaked before planting?
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. I presoak just about everything except for the tiniest seeds. But I’m always careful not to presoak my seeds until the night before planting them in pots or in the garden.
