|Are you supposed to use something for tomatoes to grow on like a vine?|
|Yes, definitely! This can be done with "tomato cages" which are commercially available, wire contraptions that offer the support your tomatoes will need. You can also accomplish the same thing by putting tall stakes in the ground and tying the tomato vines to them as they grow. This can be done with twine or even discarded panty hose. You want to avoid cutting the stems with the "ties".
Tomatoes are "staked" in order to keep them off the ground and exposed to as much sun as possible.
There are two types of tomatoes: determinate and indeterminate. Determinate tomatoes are those that grow to a certain height and then set blossoms. Usually the fruit ripens at the same time. These are good choices if you want to can or process your tomatoes. Indeterminate tomato plants put on new growth and new blossoms all season long. The tomatoes ripen at different times; good if you like fresh tomatoes all summer long.
