When and How to Plant Tomatoes
Tomatoes are warm-season vegetables. They do not tolerate cold weather well. They like the soil temperature to be around 70 degrees fahrenheit. Plant tomatoes after the threat of frost. There is a small window of time to transplant your tomatoes in Phoenix.
Plant tomato transplants between mid-February and March.
Early season varieties and transplant tomatoes work best in Phoenix. Tomatoes need room to grow and need a minimum of one foot apart.
For taller varieties provide a cage or trellis to support your tomato plants. We like to use bamboo sticks and flexible garden ties to support our tomato plants.

Types of Tomatoes- What Works Best in Phoenix
There are two types of tomato plants: determinate and indeterminate. Determinate tomato plants grow a few feet high and produce all of their tomatoes for one harvest. Indeterminate tomato plants grow tomatoes throughout the growing season.
Indeterminate Tomatoes
If you’re looking to grow tomatoes for your salads or burgers then an indeterminate plant is the best choice. Indeterminate tomato plants grow taller than determinate types. Stake indeterminate tomato plants.
Determinate Tomatoes
If you’re looking for a large harvest of tomatoes within a few weeks a determinate plant would be the best choice.
Tomato paste is often made with determinate tomatoes. Determinate tomato plants grow like a bush until it reaches a few feet.
Ideally if you plant both types you’ll have all of your favorite tomato varieties to pick from.
