The jury is still out on whether soaking seeds helps germination. Some studies have shown that soaking can indeed help, while others have found no benefit. If you're interested in trying it, there's no harm in doing so – just be sure to use sterile water and let the seeds soak for the recommended amount of time. (Usually 12-24 hours.) Keep in mind, though, that not all seeds need to be soaked; some will actually do better if they're left dry. So if you're unsure, it's always best to check with a gardening expert before soaking your seeds.
