Determinate tomato plants grow to a predetermined size, usually 3 to 4 feet tall, and produce their fruits all at once.
Indeterminate tomatoes, on the other hand, can grow 8 to 10 feet tall (or more!) in a home garden and require caging, staking, or trellising to handle their heavy, fruit-laden vines.
It’s best to start your tomato seeds indoors about four to six weeks before your last expected frost date, repot the seedlings to increase the root mass, and give them time to harden off properly to ensure strong, healthy plants.
The plants have tiny, fuzzy bumps on their stems (called adventitious roots, root initials, or tomato stem primordia) that are essentially the beginnings of new root nodes.
Sunlight is free, and it’s one of the most important aspects of growing tomatoes. For a good harvest, allow at least 8 hours of full to filtered sunlight per day for your plants.
