During the date time when the temperature is about 70 to 80 degrees, it is best to transplant the seedlings outside. I will suggest you hard them first so that the plant is able to adjust to the other environment. For that, you need to place the seedlings in the outdoors for a few hours every day for 1 to 2 weeks. You need to keep the distance for about 2 to 3 feet and plant them about 5 to 6 inches deep in the soil so that they grow a strong root system.

Place Support for Your Plants:

Water Thoroughly:

To grow tomatoes you need to water them about 121.5 inches per week. I will suggest you to water them in the early morning so that they get a good amount of water throughout the day and the excess amount of the water will be evaporated easily
