Follow the steps above, but be extra careful not to grow them in too shallow of containers. Transplanting tomato seedlings to containers is almost the same as in the ground.
How to Transplant Tomato Seedlings into Containers If you are concerned that your soil is not warm enough, try to cover it with black gardening plastic. Give them a good watering and you are set to go. You will want to space your seedlings out between 24 inches to 4 feet, depending on the variety you are growing and the size the plants will grow to. Gently pat them into place with a bit more soil. Gently place your seedlings into the ground. Gently remove the seedlings from the containers (or peel off the paper cups if this is how you grew them). Dig a hole that is about the size of the container you are growing your seedlings in. When your seedlings are approximately 3 to 4 inches in height they are ready to transplant. You’ll need 3 feet (1 m.) between the plants and 5 feet (1.5 m.) between the rows if you’re planting. Loosely tie the plants to their stakes as they grow, but set the stakes when you set the seedlings. Staking only requires about 2 feet (0.5 m.) between plants. Be sure not to plant them when there are still frosty nights ahead. Plants should be about 3 feet (1 m.) apart when tomato planting with cages. Tomatoes are from a semi tropical area so they do need warm temps day and night. Plant seedlings outdoors when the daytime temps are at least 60 degrees fahrenheit.

Each day, increase the time they are outside until you can leave them outdoors at night. To harden off, you will just take your tomato seedlings out to a semi-protected spot, such as your porch or balcony and allow them to sit outdoors for a few hours. The process isn’t hard and will just add about a week onto your time before you transplant them. Hardening off is a process that gets your seedlings ready for the outdoor elements and is a pretty important step so it should not be forgotten or skipped.
