You need to get the plants used to outdoor conditions by moving them outside during the day and back indoors at night. Should you choose to grow your tomato plants in the ground, you will need to 'harden' them first. Once your plants have reached 2-4 inches in height and have sprung their first set of leaves, they’re ready for a new home. Note that you should plant 2-3 seeds per container because not all will successfully germinate. Seedlings can be germinated in seedling trays, such as the Growneer 120 Cells Peat Pots Seed Starter Trays ( $11.99, Amazon (opens in new tab)). And planting them in the ground at a young age puts them at risk, particularly if the temperature drops at night.įor this reason, tomatoes should be kept in containers at first. Tomato plants are vulnerable while small and developing - they require constant warmth and moisture. Unless you’re planting a mature and established tomato plant, it shouldn’t be placed directly in the ground.
