5. Fertilize the soil

A water-soluble or liquid fertilizer can be a great boost for the seed or even the seedling stage. At the beginning of the growth phase, the tomato plants need a good amount of nutrients through the potting mix; giving some extra fertilizer after two weeks will help the seedlings grow healthy. The slow-release fertilizer is great for tomato plants.

6. Keep checking

Last but not the least, do check the pots regularly if the soil is getting too dry or staying wet for a long. The soil is getting drained well or not? The seedling is not showing any droopiness.
