It is important to keep the soil consistently moist while tomato seeds are germinating and establishing roots. However, you should also be careful not to overwater, as too much moisture can cause the seeds to rot before they have a chance to sprout.
A good rule of thumb is to water the seeds immediately after planting, and then water daily (or as needed) to keep the soil consistently moist but not waterlogged. Once the seedlings have emerged and are growing well, you can begin to reduce the frequency of watering, but still make sure to provide them with a deep and thorough watering once or twice a week, depending on the conditions in your garden.
It is important to remember that the amount of water your tomato seeds need will vary depending on factors such as temperature, humidity, and the size of your container or planting bed. In very hot or dry conditions, you may need to water more frequently, while in cooler or more humid conditions, you may need to water less. It is best to check the soil regularly and water as needed to keep it consistently moist, but not soaking wet.
